he congestion pricing plan for New York City has been on, off, on and off again over several years, but has finally gone ahead in 2025. Approval was given for the pricing plan by the Federal Highway Administration (FHWA). The Metropolitan Transportation Authority (MTA) introduced the toll at US$9/day, down from the previous rate set at $15/day. The money raised by the congestion pricing scheme will be invested in the city’s transit system, providing it with a much-needed financial boost.

New York City differs greatly from other major centres of population in the US. It is one of the few US cities with a public transport system approaching anything like as extensive as seen in many (or most) European cities. Crammed into a comparatively small area, New York City is more densely populated than the majority of US cities, so it is less suited to heavy concentrations of motor vehicle traffic. Parking a car in New York City can be very problematic. And it is worth noting that a far lower percentage of New York City inhabitants own a personal motor vehicle than is the norm for US cities.

The need for congestion pricing in New York City is without question though, particularly given the high population density.

According to the MTA, “Congestion Pricing will dramatically reduce traffic in the Congestion Relief Zone, transforming the area from gridlocked to unlocked. Less traffic means cleaner air, safer streets, and better transit.”

The MTA says that the city's inhabitants lose 117 hours on average sitting in traffic every year, costing them nearly $2,000 in lost productivity and wasted time. And more traffic also means more air pollution and associated health impacts.

The system will operate in part of Manhattan only. Vehicles entering the Congestion Relief Zone in Manhattan, in local streets and avenues at or below 60th Street, will be charged. The MTA says that introducing the toll will result in at least 80,000 fewer vehicles/ day entering the zone, relieving congestion in what has been the most congested district in the US. For drivers, the system will reduce traffic and make it easier to drive in the Congestion Relief Zone as it will result in fewer cars on the road. Those who still need to drive will have faster trips and spend less time in traffic. End

The $2 billion maintenance and repair project for the George Washington Bridge linking New York and New Jersey in the US is now more than 50% complete

A

ccording to the Port Authority of New York and New Jersey, the replacement of the 592 steel suspender ropes on the George Washington Bridge is nearly finished.

The replacement of the 592 ropes that suspend from the bridge’s four main cables and hold up the bridge’s two roadway levels is the largest part of the project to rehabilitate, repair or replace major components of the world’s busiest vehicular bridge. The replacement of every suspender rope and the rehabilitation of the bridge’s four main cables are essential. As the New York and New Jersey region’s primary Hudson River crossing for large commercial trucks, the bridge is a crucial link in the

06

interstate highway network.

The suspender rope replacement project, scheduled to be completed by the end of 2026, includes the construction of a newly-built sidewalk on the bridge’s south side to improve safety and accessibility while increasing capacity for path users by separating pedestrians on the south sidewalk and cyclists on the existing north sidewalk.

Morocco will invest $765 million in expanding its motorway network between 2025 and 2027. By 2030, Morocco intends to have a motorway network extending 3,000km in total, compared with 2,000km at present.

The motorway network is managed by Société nationale des autoroutes du Maroc (ADM), which has set out the expansion plans. According to ADM, traffic volumes on the network increased by 8% for 2023 compared to 2022 and are continuing to grow.

Once complete the RabatCasablanca Continental Motorway will run between the Tamesna Junction on the Rabat Bypass and the Casablanca South Ring Road at Tit Mellil.

$2 BILLION ROAD PROJECTS FOR COLOMBIA

Four road projects worth nearly $2 billion are now under construction in Colombia, with the necessary financing packages in place. These form part of Colombia’s 5G infrastructure programme, with a further two projects expected to commence in the first six months of 2025.

Colombia’s National Infrastructure Agency (ANI) says that the other two projects are now at the pre-construction phase.

Australia’s costly $16 billion East Link Project Australia’s tolled East Link project in Victoria has increased in cost significantly since it was first planned. The project was originally expected to come with a pricetag of $6.25 billion (A$10 billion) but now looks as if could cost as much as $16.24 billion (A$26 billion).

This massive jump in the price has been attributed to a series of factors. Materials and labour have become far

more expensive, particularly in the wake of the COVID-19 pandemic. Environmental legislation has also been a factor in the increased cost.

Webuild is part of Spark consortium working on the project. Webuild will design and build twin three-lane tunnels 6.5km-long, among other works. Once completed, it will be the longest road tunnel in Victoria.

FUNDING FOR INDONESIA’S NEW CAPITAL

CHALLENGING HIGHWAY BRIDGE REPLACEMENT Work is being carried out efficiently with the help of LEAN Construction

C

ontractors PORR and STRABAG are teaming up to carry out a challenging bridge replacement project in Austria for client ASFINAG. The two

firms will demolish the Lueg Bridge in Austria’s Tyrol region, replacing it with a new and improved structure.

The 1.8km Lueg Bridge forms part of the busy A13 Brenner

Highway. Carrying around 32,000 vehicles/day, the bridge is now 55 years old and this complex structure is no longer able to cope with present-day traffic volumes.

The necessary funding is being secured for the construction of Indonesia’s new purpose-built capital, Nusantara. The Indonesian Government plans to spend $3 trillion to develop the second phase of Nusantara’s construction programme. This is around half of the budget set aside for the first phase of the project, which was carried out between 2022 and 2024.

Construction is being carried out under a series of PPPs, managed by the Nusantara Capital Authority. Six road projects are included amongst the PPPs, as well as a series of infrastructure works for utilities and power supply.

CONSTRUCTION TECHNOLOGY The Smart Construction Edge solution is now available across key markets

Smart solutions for drone surveys Earthmoving solution expert, Komatsu, has combined Artificial Intelligence (AI) to modernise its Smart Construction Edge solution, in partnership with Sony as part of the EarthBrain jointventure across Komatsu, NTT Communications, Sony Semiconductor and Nomura Research Institute, to champion digitalisation and advancement in drone surveying processes.

The innovative Edge solution enables experts and beginners to perform accurate drone surveys and process drone

flights into point clouds. The EarthBrain partnership works to optimise the construction processes through digital transformation to maximise productivity, improve worksite safety and environmental sustainability.

With its latest Edge evolution, Komatsu Smart Construction now offers a terrain mapping tool utilising AI to remove obstacles, such as machinery and buildings, from drone surveys. This reduces the need for manual amendments once the data has been captured.

When the main surveyor of medium-sized Belgian earthmoving company, CROES VS, went on maternity leave, the company faced challenges to maintain its surveying capabilities making it difficult to carry out its projects with the same level of precision and efficiency.

CROES VS implemented the revised Edge technology and the workload gap was filled without the requirement of additional training or recruitment. The solution allows various team members,

including the marketing manager, to take on drone surveying tasks and capture survey-grade earthmoving progress, identifying challenges and opportunities within seconds.

Komatsu Smart Construction experts utilise digital tools to assist clients in earthmoving and quarrying by finding the optimum way of using resources for better productivity, quicker project completion, cost savings, improved safety, and reduced CO2 emissions.

construction and infrastructure industries, this solution helps minimise the risks associated with land and structure instability by enabling faster and more cost-effective deployment for a greater range of project types.

The new monitoring solution will connect a GNSS Meter, powered by Worldsensing, with Trimble T4D monitoring software to automatically transform data into actionable insights.

The GNSS Meter is a sensor featuring real-time kinematic (RTK) technology and the ability to process data directly on the device, providing precise and automated measurement of 3D surface movements once placed onsite. The sensors then transmit movement data to T4D for real-time analysis and if exceeding established thresholds, to automatically alarm stakeholders.

Advantages of this new

solution include ease of use with a user-friendly set-up and intuitive interface allowing rapid deployment of tens, hundreds or even thousands of sensors possible with minimal training. This reduces the time and cost associated with traditional GNSS-based movement monitoring systems while ensuring longterm sensor reliability. This solution leverages wireless IoT technology to minimise infrastructure costs, eliminating the need for extensive cabling and reducing maintenance expenses. It also reduces the number of components and accessories needed when compared to traditional systems. The GNSS Meter’s RTK technology and edge processing achieves reliable, millimetric precision, enabling deployment across a range of project types and environments.

IRF launches international registry for road safety auditors The International Road Federation (IRF) has launched an International Registry for Road Safety Auditors, establishing a global benchmark for training and certifying road safety auditors. Unveiled during the IRF World Congress 2024 in Istanbul, this initiative - supported by TotalEnergies aims to enhance the quality and consistency of road safety audits worldwide.

With over seven decades of leadership in road safety, the IRF has been instrumental in supporting governments and organisations to train and certify auditors. This registry responds to the rising demand for highquality audits, particularly for infrastructure projects financed by multilateral development banks (MDBs). By providing an accessible, transparent, and digital platform, the registry ensures that stakeholders can easily identify and verify the credentials of qualified auditors, thereby enhancing transparency

and audit quality globally.

Accessible via the IRF website at www.irfofficial.org, the registry is managed by the IRF and operates as a comprehensive platform. Auditors can apply through a straightforward process that screens, verifies, and records their qualifications, certifications, and experience before granting listing. MDBs, governments, and other stakeholders can use the registry to ensure that selected auditors meet international standards and strict professional qualifications.

“This registry is a game-changer for global road safety,” said Dimitris Mandalozis, president of the IRF “By setting clear international certification criteria, we are not only improving the quality of audits but also providing a vital resource for governments and organisations committed to safer

roads.”

The registry is part of a broader three-year project supported by TotalEnergies.

It includes training and certification programmes, which have already taken place in Tanzania and Uganda, with further training scheduled in India. The initiative aims to accredit 450 auditors by the end of the project and foster the creation of national accreditation bodies, particularly in low- and middleincome countries.

“Our commitment to road safety is unwavering and that is why we are pleased to support this initiative. We believe that a true spirit of collaboration, of innovation, and proactive measures, are the recipe that will allow us to significantly reduce road traffic deaths and injuries," said Jacques-Emmanuel Saulnier, general delegate of the TotalEnergies Corporate Foundation, speaking at the launch event.

Peru’s capital, Lima, is to benefit from a massive new international airport, which will be one of the largest in Latin America

S

The new terminal for Lima’s Jorge Chavez Airport will boost passenger capacity significantly

Global Highways Magazine for industry related discussion

ophisticated construction technology solutions have been playing key roles in the delivery of Peru’s massive Jorge Chavez Lima International Airport project.

The contract to build the new facility was awarded to the Inti Punku consortium, which comprises Spanish firm SACYR and Peruvian company Cumbra, to construct the US$2 billion airport project for Lima, capital of Peru.

Lima’s upgraded international airport will be one of the largest in Latin America and SACYR has a 51% controlling stake in the construction project, with Cumbra holding the remaining 49%. Meanwhile, the Spanish engineering firm Cemosa provided much of the design work for the project. The airport authority, Lima Airport Partners (LAP), has a 40-year concession to operate the facility. LAP is part of the Fraport Group, which operates over 30 airports around the world, with an 80.01% stake, and the International Finance Corporation, part of the World Bank Group with 19.99% stake.

The airport first opened in 1960 and is already one of the largest and best-connected in Latin America, while the upgrade work will further boost its presence in the aviation sector. Named after Peru’s famous pioneering aviator, Jorge Chavez, the airport sits on a massive site. At its peak, up to 7,000 people have been working on the upgrade project. One innovative feature of the new facility will be the novel seismic isolation system for the airport terminal, which covers an area of 270,000m2, has five levels and will have the capacity to handle around 40 million passengers/year when complete. This isolation system will ensure protection of the structure in the event of an earthquake, a necessary feature as Lima is in a zone known for seismic events.

Third-party investment for the construction of the Airport City will exceed $400 million in the first phase, in addition to the $2 billion that LAP is investing in the Expansion Project overall.

Carrying out the project has brought advances to Peru’s construction sector, with the implementation of various new technologies. The project team has been utilising modern building information model (BIM) systems and advanced surveying, grade control and coordination systems. The scope of the project covers the earthwork, infrastructure and building construction for the new airport facilities, including a large parking lot and taxiways, asphalt paving in terminal and commercial areas, and the installation of underground utilities.

AIRPORT UPGRADE

A key feature of the new airport is the new runway that measures 3,841m in length, long enough to be used by the largest commercial aircraft, and which also benefits from the latest lighting systems.

The runway has been paved with an asphalt surface 40cm thick, paved in three layers. To ensure optimum quality, the firm used two pavers working in echelon.

This helped deliver a quality surface with a hot-to-hot joint, eliminating the risk of future water ingress and ensuring that there will be no future problems from freeze-thawing. Special grades of asphalt suitable for aviation purposes were selected for the project, meeting the US P401 and P403 standards. Similarly, aviation grade concrete meeting US standards was also used for the aircraft parking areas, which total around 70,000m2.

Carlos Ruiz Miranda from SACYR has been acting as chief surveyor for the project. He said, “One of the main concerns was synchronising design data and information flow between the field and office to facilitate the execution of the project.”

He said that to further ensure a quality paved surface, the firm utilised Trimble’s PCS900 3D control technology on the asphalt pavers. This has been a significant step and commented, “This is the first time we’ve used it in Peru.”

In addition, the PCS900 3D system has also been used on the concrete pavers carrying out the concrete surfacing work. Because this was the first time sophisticated 3D technology has been used in Peru, Trimble provided the training and support needed for the paving crew.

Building the new runway has been a complex process. He commented, “It took two years for all the earthmoving work and to complete the asphalt.”

In addition to being used for the new runway and the aircraft parking areas, 3D technology has also been utilised to deliver 10km of internal roads within

the facility allowing for ground traffic around the site.

Ruiz explained that the use of 3D technology was not part of the original plan for the airport. He said, “They started with conventional techniques and then realised they could do it a better way.”

However, using this technology for the project has delivered distinct advantages for the construction partners. Ruiz said, “We increased production and reduced human error as well as cost.” He continued, “The levelling of the concrete is perfect.”

Data was delivered directly to the asphalt paving equipment as well as the concrete paver from the project team’s BIM Department, using Trimble Connect. Ruiz said, “We sent data to the machines and then recovered as-built data to our computers.”

In addition, Ruiz explained that utilising 3D systems meant that the construction team was also able to complete both the concrete paving and asphalt paving components of the project ahead of schedule.

The project was designed to the latest BIM standards, with around 2,700 active BIM models and including more than 80km of utilities that will be constructed by multiple contractors.

“With this many BIM models, trying to ensure that everyone in the field was working to the latest model or geometric modification, even just managing survey control, stakeouts and grade checking, was proving to be a challenge,” said Ruiz. “We needed a way to better share data.”

The engineering team utilised design review and cloud-based collaboration software to coordinate design. However, these tools do not have the features that connect the field and office, according to Ruiz.

field-to-office-to-field digital workflow that has improved coordination and productivity across departments, while most importantly, keeping the project on track.

The first step in his plan was to implement a cloudbased common data environment (CDE). He opted for Trimble Connect. Ruiz explained, “This technology provides us with a centralised collaboration platform.

It synchronises the right information at the right time, providing automatic interference reviews while supporting CAD analysis. The construction crew and field surveyors have everything synchronised in that platform. Information is automatically available in near real time.”

This CDE became a central hub for managing data from field solutions that might include laser scanners, uncrewed aerial vehicles (UAVs), grade control systems, total stations and GNSS systems that gather positional data to centimetre accuracy, and a range of heavy equipment from excavators to paving systems, Global Highways Magazine for industry related discussion

which were equipped with machine control systems.

A critical part of the terminal expansion is for the new aircraft parking areas that surround it. The team employed the Trimble GCS900 Grade Control System guided by a Trimble Universal Total Station (UTS) on a Cat 140K motor grader to meet the strict tolerances on subbase and base layers and the Trimble PCS900 Paving Control System on an asphalt paver for improved accuracy and quality control.

Trimble WorksManager has been used for the transfer of data from the office to the machines at the jobsite. This ensures that current models were loaded on the machines and that the as-built conditions met the tight specifications defined by the owner. Trimble WorksOS Software tracked jobsite productivity.

“The combined paving and grading systems allowed us to work in large areas with efficiency and accuracy,” said Ruiz. “We’ve seen a significant reduction in rework because the deviations from design grades are minimised. I showed the WorksOS layout report from GLOBAL HIGHWAYS 2025 VOL. 1

the PCS900 to my manager. It showed that our crews are paving to 10mm accuracy, well below the 18mm requirements. If there were issues, the near real-time data collection and reporting tools allowed us to identify and resolve them quickly.”

With so many pieces to this project in the terminal and surrounding areas, the SACYR survey team found that an essential technology allowing office-to-field data workflow has been augmented reality (AR).

“Initially, we tried using paper printouts to manually check for issues in the field; we tried Google Earth, but that was not satisfactory,” said Ruiz.

Instead, SACYR turned to Trimble SiteVision augmented reality software to collaborate and manage tasks between all the different groups and departments of the project with real-time visualisation of data to support decision-making and provide

insight into potential issues.

“Using Trimble SiteVision on infrastructure projects offers significant advantages,” said Ruiz. “It facilitates accurate, real-time visualisation of data, improving decision-making and planning and allows effective communication between teams, reducing errors and costs. In addition, it improves efficiency and precision in project execution, which translates into a higher quality result and shorter deadlines. In short, Trimble SiteVision is a valuable tool for optimising the management and execution of infrastructure projects.”

Tasks can be assigned and statuses tracked to help coordinate work across teams. He found that any issues or anomalies detected during construction can be more easily communicated and addressed. It helps synchronise inspection/quality check processes to ensure all parties are using the latest information.

“On this project, it is an important tool for managing the many moving parts and stakeholders,” said Ruiz. “The visual interface provides a terrific oversight of project progress.”

Ruiz added, “The use of technology on this project has helped us manage all the many pieces of this massive effort in a more collaborative manner.

There’s better organisation of the information in general, which has reduced human error and greatly improved access. Bottom line, the entire team is just better connected.”

With the completion of the new runway, the existing runway is being closed for resurfacing with asphalt as well as the installation of new lighting. “To meet the new standards,” Carlos Ruiz commented. This paving work for the existing runway is scheduled to commence in June 2025.

When the upgrade of the existing runway is complete, the airport will have two runways that will be able to handle flights simultaneously and which will feature the latest aviation technology, boosting capacity as well as safety for travellers.

The geology of the site has not posed issues for the project team. However, Ruiz said, “The biggest challenge came from the dimensions of the airport, which required a lot of work and a lot of documents.”

Design changes would have posed challenges given the size of the project but the project team used Trimble Connect to upload design changes and ensure that these could be implemented quickly to all partners.

INTERVIEW: TOPCON

TOPCON: INNOVATION LEGACY DRIVES DEMOCRATISATION

Topcon has a legacy of innovation with positioning technologies, and is now translating these groundbreaking inventions into affordable solutions - the democratisation of technology - to meet the needs of clients today.

Ray O'Connor, formerly the CEO and President of Topcon Positioning Systems, is now Chairman. He and Ivan Di Federico, who is now President and CEO, explain what it takes to create a future built on a strong heritage.

David Arminas reports.

GH: You both have years of experience in the industry and the sector and seen many changes.

What might be the top strategic priorities for Topcon Positioning Systems going ahead in this particular age of fast-moving technology?

Ivan: It's always been at the heart of our strategies to look at the market and what our customers need. This is our top priority and is certainly something that we will continue to do. We pay a lot of attention to how the market is evolving and where the customers feel the most pain in their workflows, in what they do, day by day.

Ray: We have to figure out how we can drive the cost of this new technology to a lower price point. And focus on the training and the capability of people to use this equipment and make it easier for them to use it. This is critical for the success of the business overall.

There's not going to be any machines that don't have automation attached to them. So, as we go forward, we need to get the price and the training to where we need it to be. Every machine needs measurement equipment on it. Every machine. You need to know where the machine is all the time and what is the workload that the machine is doing.

22

GLOBAL HIGHWAYS 2025 VOL. 1

Ivan: This will enable what we call the democratisation of the technology. Make it simple, make it at a cost for the customer that is affordable so that each and every vehicle can have one piece of technology. And for every company to have the services that come with it in their cloud environment.

This democratisation of technology is making technology much more accessible to companies and to individuals who become much more efficient in their processes.

GH: How would you describe the culture you've helped create at Topcon Positioning Systems to move forward these technological products and advances?

INTERVIEW: TOPCON measurement and all the new technologies that have come out in the past 10-15 years. And allowing that to drive price down. A big part of it is training and teaching people how to use the technology.

Ivan: You can see the precise results obtained by automating operations of machinery. This is really the strong element of our culture. To live a dream, to transmit this dream through engineering, through testing the parts, to the sales and marketing of these parts and then eventually to our customers and to the market in general. All in order to change the world.

"A customer will feel a pain. It's up to us to really understand what that pain is"

Ray: I would also say we’re a little bit unique from a cultural standpoint. We grew this business up in Livermore, California, but we have a Japanese parent company with a lot of entrepreneurialism which is very helpful for us. We didn't have to get a return on investment in the first week or the first month or the first year. We were investing for the long term of the business. I think that stands us in good stead here at Topcon and helped create the culture that we have inside the business.

GH: What are these market changes that you've seen over the years?

Ivan: A customer will feel a pain. It's up to us to really

BELOW Thermal MapperDocument and view asphalt temperatures in real-time

understand what that pain is. We will consider what is redundant in what the customer is doing. What could be done better? The vast majority of the market tends to use what already exists to solve problems but they still feel the pain and they don't actually know how to fix it. They realise that they are doing something in a certain way and see how difficult it is.

And we have to pick that up that and work with our product management team, with our engineers. This

GLOBAL HIGHWAYS 2025 VOL. 1

is something we have done very effectively: invented products that have really revolutionised a field because the products have been used to change the way customers do things. The litmus test of success is that if after they first buy and use that product, they continue to buy it. If customers never revert to the old technology, then this is a sign that we really interpreted what was their pain point.

GH: Do you see new market threats, new competitors entering the sector, disruptive technologies?

Ray: Oh, absolutely. We create this new technology, move it out into the marketplace and other companies see that it creates more business. There's always going to be followers. That's just a natural part of doing business. And we're very proud of staying on top of the technology. So, I think we're in great shape, even with more competition. To me, it's really good for the market and good for us as a business. It makes us stay sharp, but we have to be open enough to recognise and understand that we're not inventing every single solution. We see what competition is doing and we compete.

GH: How will you drive innovation and new ideas moving forward to meet these changing market trends and needs by the customer?

Ivan: We have an advanced research team and we have several activities inside the company that bring us innovation, flashes of what the future can be. At this moment we have more than 5,000 patents, of which around 2,600 are probably active and we continue to generate patents at a very high rate, like ten or so a month. That's an indicator of our high level of R&D.

INTERVIEW: TOPCON

GH: What are two of the biggest obstacles facing Topcon Positioning Systems right now and how will you overcome them?

Ray: One of the biggest obstacles for us is getting people who really understand the business and the installation rates of technology, how fast we can get equipment on machines, that sort of thing, to show the benefits of our technology. If we had a hundred more dealers with the expertise to do just that, it would really speed up our adoption rate. But this takes time and we are building this model as we go forward.

Ivan: Yes, that's probably the single biggest bottleneck for our business. But another barrier to market product acceptance can come from regulations. Right now, regulations about things such as communication standards and so forth are old. So, while the regulations may speak about how to transmit the radio waves, they don’t talk about standardisation for the sector now that we have moved forward with video and stuff like that. Every time we have a standard, it opens up a much larger market and makes it possible for us and for others to try harder to innovate. More attention also should be paid by governments to enable the use of more open platforms.

GH: What's the coolest bit of technology that you've seen come out of Topcon Positioning Systems? What has been something that you think is extremely innovative?

Ray: Oh, wow! I can list a hundred components and technologies. I'd say one of the biggest is the IMUs, Inertial Measurement Units. When we first started in the business, one IMU from Honeywell, I think, that Global Highways Magazine for industry related discussion

you'd put on a motor grader, cost $26,000. Today, we’re building those sensors for about $300. You're not going to sell a lot of motor graders if the cost of one component is $26,000 and the system is $100,000 to manufacture and you’ll then have to sell it for $200,000 or $300,000. You might sell a few but certainly not a lot.

Fortunately, Topcon Positioning Systems is located on the edge of Silicon Valley [in California] and we are very much in touch with companies that are inventing and developing products and technology. You can even talk to the engineers that invented it. That's the benefit of having a location close to Silicon Valley. But Ivan is the engineer so from a technology standpoint this conversation could go on for four or five hours probably.

Ivan: You know, I've been part of this, our history and technologies, for such a long time. I tend to have feelings probably like a mother for each and every one of our inventions. I'm very jealous and it’s very difficult for me to see who's the best kid because there is none, I can’t choose! I love them all. If I have to summarise this in one word, the best technology is always the next one that I'm working on! There's a lot of love put into these products and we know them so intimately and once something is released, I'm always thinking of the next generation. And even two generations ahead.

That's the beauty of this company. Topcon Positioning Systems allows me to do this.

KEY EQUIPMENT LAUNCH

VOLVO CE’S NEW ADT RANGE Volvo Construction Equipment is looking to cement its position in the articulated dump truck (ADT) market with the launch of its new seven-model range

H

igh performance coupled with increased driveline efficiency helps to cut cycle times as well as fuel consumption and the firm is bullish for sales success. “This is the biggest articulated truck launch ever,” said the firm’s president, Melker Jernberg. Volvo CE says that these new ADTs offer a range of major gains over the models being replaced.

And the new range also includes an all-new size class, the 45tonne capacity A50, which slots into the range between the proven A45 and A60 models. “It’s a brand new size class for us,” Jernberg commented.

The new transmissions help to reduce fuel consumption by up to 15% and coupled with the faster cycle times, this should help lower the cost/tonne for customers according to the firm.

The sophisticated hydraulic suspension is fitted as standard on the larger machines in the range and available as an option on the smaller models. This provides a smoother ride for the operator, as well as reducing wear and tear on the machine.

Operator safety is always a high priority for Volvo CE and there are several improvements for the new generation trucks. These include a bigger cab entrance for the operator, new hand rails, additional lighting around the machine and better camera systems. This last is a key feature, with a camera that shows forward view if the speed drops below 10km/h. In addition, the smart camera system shows the way ahead on the incab display automatically when the truck is climbing a steep slope and also switches automatically to a

rear view when the operator starts reversing. Another camera shows the articulation joint so that the operator can see if anyone is in the danger spot.

This new launch follows in the wake of others from the firm, which has upgraded 35% of its range in recent months. Special models will be available as options in the future, including a 4x4 variant and low height cab models for use in tunnelling applications. To highlight the green credentials of these new models it's noted that the range is made from steel produced with a low carbon profile, as well as featuring a high percentage of recycled steel.

Volvo CE produces 3,500 trucks/year and Jernberg commented, ”We are the world market leader in articulated haulers. The great thing about the articulated hauler is that it is versatile.”

He added that global demand for ADTs has grown in the last decade, with the US commanding the biggest slice of the market and with Indonesia and South Africa also accounting for high sales volumes.

Market demand for ADTs has changed over the years with the 36-41tonne capacity models dominating, compared with the 23tonne capacity machines that were favoured in the earlier years of the ADT. Jernberg commented, “The A40 and A45 form the backbone of Volvo CE’s market.”

The new generation A40, A45 and A50 models are available now, with the A25, A30, A35 and A60 starting in production and available later in 2025.

As with other Volvo CE construction machines, build quality is optimised, with checks being made on the ADTs throughout assembly and again once the models are complete. Tina Taylor, head of quality commented, “At the test track we test every ADT we produce before we ship.”

For the moment, the ADTs all use conventional diesel power but the firm has been researching a prototype fuel cell machine. With a full range of allelectric machines planned by Volvo CE, an electric ADT will be available at some point, with a diesel electric hybrid also a future possibility. A variant with an internal combustion engine but fuelled by hydrogen is likely at some point also, although a hydrogen fuel cell model looks somewhat further in the future. Jernberg said, “We are investing more than ever in research and development.” End www.volvoce.com Global Highways Magazine for industry related discussion

ROAD MARKINGS

DRIVING TOWARD VISION ZERO: A UNIFIED EFFORT FOR SAFER ROADS Eliminating road fatalities across Europe demands a collective commitment from the entire road marking sector - both public and private. Collaboration and innovation are essential to building safer, more sustainable, and more efficient road networks, from major highways to local bike lanes. As a global leader in road markings, Geveko Markings is dedicated to this mission, actively supporting Vision Zero and striving for even greater road safety advancements

A

s a leading manufacturer and supplier of road marking materials, Geveko Markings has spent the past 100 years enhancing road safety with products designed to meet the highest standards of quality and durability - and they are committed to continuing this vital mission. With a clear focus on the future, sustainability and inclusive infrastructure, Geveko Markings continues its journey towards making the roads safer.

“At Geveko Markings, road markings are more than lines on asphalt. They are lifesavers that increase safety and provide direction,” says Per Nielsen, business unit director for northern and central Europe. “While developing durable, high-performing materials is a complex process, our aspiration is simple. We are driven by a vision to create high-quality marking materials that guide, inspire and protect millions of people every day.”

Global commitment The Vision Zero initiative has transformed the approach to road safety. It emphasises shared responsibility among governments, manufacturers and individuals. The European Union has adopted this ambitious initiative, aiming to eliminate road fatalities by 2050 through different strategies. These include lowering speed limits, creating pedestrian-friendly infrastructure and incorporating advanced safety technologies.

Road markings are a fundamental part of bringing these strategies to life as they maintain the orderly flow of traffic, helping reduce congestion and accidents.

They provide crucial visibility at night and during adverse weather, ensuring safety even in challenging conditions. With the rise of advanced driver assistance

systems (ADAS), the durability and visibility of road markings are becoming even more essential, serving as guides not just for human drivers but also for autonomous vehicles.

Henrik Nielsen-Thorup, regional sales manager for the Nordic region, explains how Geveko Markings’ products exemplify this. “Our Type II markings deliver exceptional visibility in wet or dark conditions, ensuring safer navigation for both humans and ADASequipped vehicles. For example, we have developed a hot-applied thermoplastic which is applied in a unique droplet-shaped pattern and used with great success on Danish highways. This future-proof solution enhances safety in two ways. It provides high visibility in challenging conditions and delivers audible rumble noise and noticeable vibration when crossed to alert drivers.”

With advanced road marking solutions like these, Geveko Markings demonstrates how infrastructure improvements can play a critical role in advancing Vision Zero’s objectives for safer roads.

Sustainability: A road forward As the EU places increasing emphasis on sustainable transport, Geveko Markings is committed to developing more environmentally friendly solutions.

The company is actively focusing on creating materials designed to reduce carbon footprints, aligning with the EU’s Green Deal objectives.

Road markings are essential for promoting sustainable transport modes such as cycling and micromobility. Geveko Markings’ products help create dedicated lanes and safe zones for bicycles

and e-scooters, making streets more inclusive and accessible. By supporting these sustainable transport modes, these markings contribute to healthier, lowercarbon urban environments and encourage the shift towards greener cities.

Clearly defined spaces encourage people to choose sustainable transportation options, directly supporting Vision Zero’s twin goals of safety and sustainability, notes Arnaud Derasse, Benelux region manager. “This approach highlights Geveko Markings’ commitment to innovating for a greener future while balancing road safety and encouraging a shift away from car dependency, lowering emissions and fostering more accessible urban spaces.”

Certified quality Geveko Markings ensures rigorous testing and validation, including practical road trials, to establish quality and performance of all its products, explains Moritz Bähr, head of product management for Europe.

“Certification is our promise of quality. It guarantees that our materials meet all technical requirements, providing safer traffic flow for everyone,” says Bähr.

“By developing and continuously fine-tuning solutions like preformed markings, hot-applied thermoplastic and plural-component systems, we make sure that our product portfolio ensures the right fit for diverse traffic and environmental demands.”

The European Union's focus on smart and selfexplanatory roads aligns closely with Geveko Markings’ goals. As the EU’s Expert Group on Road Infrastructure Safety (EGRIS) works toward standardised markings, companies including Geveko Markings play a critical role in translating these policies into practice.

Uniting for safer roads But in the pursuit of safer, more sustainable and efficient mobility, it is imperative for the road marking industry to unite and embark on a collective mission.

This will also involve engaging politicians, civil servants and specifiers to elevate the importance of road marking materials and enhance the performance and testing of these products. Achieving the ambitious aim of eliminating fatalities on our roads necessitates a deeper collaboration within the road industry to overcome existing barriers, such as funding and procurement challenges that hinder swift adoption of innovative solutions.

Surveys conducted by the Local Council Roads Innovation Group in the UK show that local councils often lack the necessary resources and expertise to implement cutting-edge road marking solutions.

Therefore, fostering collaboration across the supply chain and forming strategic partnerships with local authorities is crucial.

Geveko Markings exemplifies the power of such partnerships, showcasing how private companies can support public authorities in realising ambitious objectives such as Vision Zero. “Our collaboration with lobbyist associations is vital to us,” says David Bryant, director and country manager for the UK and Ireland.

“It focuses on increasing attention to road marking materials and the performance and testing of road marking products to continuously enhance road safety.”

By working together, the road marking industry can make significant strides toward achieving a safer and more sustainable transportation environment for all.

Safety for everyone Cities worldwide face an urgent need to update their infrastructure to accommodate increasing city centre traffic. One effective solution is to encourage a shift from cars to smaller, eco-friendly transport modes micromobility. For micromobility options to become reliable alternatives to traditional transportation, safety is essential. People need to feel secure when using them. This starts with well-designed spaces and dedicated lanes designed to accommodate a clearly defined traffic separation with safe zones for vulnerable road users such as pedestrians and cyclists.

“Whether it be coloured areas, safe parking or clearly marked bike lanes, our markings allow vulnerable road users to ride safely at their own speed,” explains Alexander Sezer, country manager for Germany, Austria and Switzerland. “This creates fewer risks of accidents without affecting the flow of road traffic.”

Journey continues The integration of ADAS, the push for net-zero transportation and Vision Zero commitments are the future of road infrastructure. Geveko Markings is poised to take part in this transformation to a safer and more sustainable tomorrow. “When we talk about our passion for road markings, it is not just about lines on the road,” concludes Nielsen. “It is a passion for futureproofing traffic with ADAS. A passion for sustainable development with micromobility. And a passion for ensuring that all road users feel safe in traffic.” End • Produced in association with Geveko Markings

ROAD SAFETY

WEIGHING UP WIM Despite the benefits, including safer highways and possibility of automated legal weight enforcement, obstacles remain for faster uptake of weigh-in-motion, WiM, systems. David Arminas reports on the manufacturers’ perspective.

V

astly improving weigh-in-motion (WiM) technology can help combat overloaded vehicles and improve the safety of the world’s highways. They can help road and bridge designers and also aid highway agencies and owners with enforcement of road weight restrictions.

The market is increasing for these systems but obstacles remain. “Most tenders tend to rely on parameters that were in the distant past,” says Florian Weiss, chief executive and owner of Traffic Data Systems in Hamburg. “The issue is really that the people writing the tenders are not familiar with the technology and they might use a consultant to write it.” This is the situation in Germany at least, where, he says, the market is at a virtual standstill.

“The Q-Free Infomobility team is seeing significant growth for WiM systems globally,” says Oliver Bain, managing director of Q-Free UK and vice president of Q-Free Infomobility, the group being based in Trondheim, Norway. “Road authorities increasingly recognise the social and financial benefits, anything from statistical reporting to direct [law] enforcement.”

He says that fully automated enforcement systems are being adopted in more countries. “New operating models, such as data-as-a-service and the decreasing cost of obtaining WiM data and acting on it are making WiM systems more accessible to both local and central government departments.”

Infrastructure preservation and road safety are primary reasons for implementing high-accuracy WiM, explains Leonardo Guerson, WiM product manager and application engineer with Intercomp, headquartered in the US state of Minnesota. “These reasons are central to road enforcement efforts worldwide and WiM applications are prioritised in such contexts,” he says.

Global Highways Magazine for industry related discussion

Another significant application that has gained momentum in recent years is the use of WiM data for pavement design and management. “Advanced pavement design methods, such as the United States (WiM) technology site-specific load data into their algorithms,” says Guerson. “High-quality WiM data is essential for accurate calculations and ensuring a road service life that meets design expectations.”

“The field has witnessed notable advancements in sensor, hardware and software capabilities,” says Roy Czinku, vice president of ITS solutions and maintenance services at Quarterhill, headquartered in the city of Saskatoon in the Canadian province of Saskatchewan. “Thanks to these improvements, WiM systems provide more accurate, reliable and repeatable measurements than ever before. We've also have seen improvements in how WiM handles vehicle dynamics and temperature variations.

Improvements to connectivity have significantly expanded the scope of what WiM systems can achieve, particularly in terms of data accessibility and sharing.”

Václav Blahnik, product manager of WiM technology at Cross, based in the Czech Republic, believes the primary reason for WiM adoption is the cost savings on road repairs. “These costs can be quantified and then presented to state authorities and the public, thus justifying the investment in the acquisition of WiM systems,” he says. “Increased safety is also a decisive factor but its demonstration is problematic because it is not easily quantified and is rather subjective in nature, involving many difficultto-grasp variables.”

Suppliers and manufacturers of WiM systems have believed, says Traffic Data Systems’ Weiss, that dynamic low-speed WiM as a legal weight direct enforcement tool would drive the market. But regulations covering their use are slow in coming.

“You can use such systems in Germany, but not for legal enforcement, which is the key. To allow for this, rules, regulations and laws have to be changed. This is something that can take 10 to 15 years.

“You can use dynamic weighing for collecting statistics and preselection of vehicles to be statically weighed. But dynamic weighing for legal enforcement is where the systems can make money. We do not have the legislation to operate them.” Weiss says that Germany is not unique among European countries.

Blahnik, from Cross, believes that for collaboration or cooperation there must be a legislative framework, especially for direct enforcement, where departments of transport set the rules. “In connection with it, the metrological authority must define clear metrological requirements and conditions under which such a WiM system can be operated,” he says.

Some form of collaboration between the private sector, departments of transport and local government authorities in WiM applications has always been important and is likely to remain so, says Guerson from Intercomp. “This is because of a trend toward performance-based WiM contracts. WiM data collection is delivered as a service and all aspects of implementation are managed by a single company or a consortium of companies.”

Guerson believes that this model has proven effective globally, as the success of WiM applications depends on various factors, including site selection, installation, calibration, operation and maintenance.

“Consolidating responsibility within one party and managing these contracts based on performance typically results in improved uptime and higher data quality.”

Quarterhill’s Czinku agrees. “Historically, government entities such as highway and motor vehicle enforcement agencies have been instrumental in running and authorising traffic data and weight compliance programmes. However, as we witness more roadways operating with private investment, toll authorities also

GLOBAL HIGHWAYS 2025 VOL. 1

have an interest in critical enforcement and safety data.”

Czinku says there has been “an evolutionary shift in the funding model” for WiM systems. “For example, an as-a-service model offers various levels of engagement ranging from purchasing full systems and managing them independently to adopting a hybrid approach or fully subscribing to a managed service.”

Advancements in technology, including tyre anomaly detection and vehicle-to-everything (V2X) communications, are enriching the WiM data ecosystem. This benefits planners, road operators, drivers and safety and enforcement agencies.

With the capacity for real-time data growing and technologies evolving to create interoperable networks, collaboration across jurisdictions and with a multiplicity of stakeholders are not just advantageous, but becoming necessary for overall system efficiency gains.

Because WiM systems are getting more sophisticated and their data more accurate, it makes sense for the supplier and manufacturer to get much more involved in their use and performance.

Wang Ping, WiM chief technical officer of Vanjee Technology, based in Beijing, already sees a move away from the original contract type where departments of transport and local authorities fund construction and operation of a WiM system. The trend, he says, is for the private sector to build the WiM system and then help the departments and highway authorities to operate them.

While the financial pressure on DoTs may be reduced, it also means that private sector companies - unless they are very good at similar services in other areas - will now be under a lot of performance pressure in terms of product and service quality, as well as funding, says Ping.

General financial constraints are also being felt more and more by infrastructure planners, roads operators and maintenance staff. It is something of a perfect storm for them. At the other end, they see road damage on the rise due to the increasing weight of personal and commercial vehicles. Payloads are up and heavy batteries are boosting the weight of the increasing number of electric passenger vehicles. In fact, this has inflated vehicle weights by around 25% in recent years, estimates Bain, from Q-Free.

Even with some push-back from the public sector which has concerns over the cost, there are enough forward-looking authorities and agencies to make the market look favourable for suppliers and makers of WiM systems. Bain believes that the arguments for the installation of more WiM systems are inescapable.

While the reasons for implementing WiM vary, more authorities and departments with different priorities are recognising its value. WiM is becoming more commonplace and used by a diverse range of customers to improve safety, reduce costs and make more informed infrastructure decisions.

LOW CARBON PAVING IN THE UK

Tarmac and National Highways deliver groundbreaking carbon savings in strategic road network resurfacing trial

A

cutting-edge trial on the A64 has delivered the UK’s lowest carbon resurfacing scheme on the strategic road network without using carbon offsetting. Tarmac, a CRH Company, and National Highways, together with supply chain partners, successfully reduced carbon emissions on the project by 75% compared to a traditional maintenance project of a similar scale, with over 260tonnes of carbon savings delivered.

The trial – the first of its kind on the strategic network – was delivered on a 2.5km section of the A64 eastbound carriageway at junction 44 near Bramham in North Yorkshire.

Over a seven-day period the team, including HW Martin, Premier Roadmarkings, Kier and Mway Comms, combined an extensive range of innovative low carbon materials, use of innovative paving technology and plant equipment to deliver significant carbon savings.

Overall, 41.3% of the project’s carbon reduction total was delivered using low carbon raw materials, 14.7% from the transport of materials and the paving process, Global Highways Magazine for industry related discussion

including the use of electric plant equipment, and 44% from employing sustainable manufacturing techniques.

A warm mix asphalt was used together with a pioneering ‘carbon sink’ bio-component binder from Shell, which locks carbon into the road. The lower layer of the pavement used 40% recycled asphalt planings (RAP) with a further 20% in the surface course to help reduce the need for primary materials.

Several zero emissions plant vehicles and prototypes were used including electric and hybrid road rollers and an electric bond coat sprayer, minimising noise and further reducing tailpipe emissions and CO2.

Tarmac’s Cross Green asphalt plant in Leeds, which supplied materials used on the project, used a combination of biofuel and electricity.

Other construction methods delivered benefits including better pavement life and a high-performance, smooth pavement. This was achieved through continuous echelon paving, with asphalt laid across the entire road surface.

Patching paving with Roadmaster A novel road patching system from Roadmaster is proving its worth at repairing roads in Iceland.

The Icelandic Road and Coastal Administration (IRCA, or Vegagerðin) recently took delivery of the country’s first Roadmaster spray patcher. The machine’s novel in-place aggregate and road surface preparation technology is said to deliver an optimal curing environment for repairs. This allows patching to be carried out below the temperature range usually considered for the spray injection patching technique.

With conventional systems, the drop in

ABOVE Using the novel Roadmaster machine for pothole patching has allowed repairs to be carried out in Iceland later than previously possible

temperatures across Iceland means that surface dressing emulsion can only be used until July, after which the colder conditions prevent curing. Instead, maintenance operators switch to a binder with added ethyl ester, which lowers the viscosity of the mixture so that it can be applied at lower temperatures. However, this modified binder is prone to bleeding, which can require repairs, increasing maintenance needs.

Iceland’s northerly location presents challenges for road maintenance. The IRCA is responsible for the maintenance of 13,000km of roads across Iceland. The road system is modern but increases in heavy traffic have resulted in rising maintenance requirements and problems with bearing capacity.

Vegagerðin maintenance management leader Jon Helgi Helgason said that the new Roadmaster machine will extend the use of emulsion later in the year.

GLOBAL HIGHWAYS 2025 VOL. 1

ASPHALT PAVING “There is a lack of knowledge of emulsion in Iceland”, he said. “Roadmaster will allow us to explore and test slowly. We will be able to use emulsion longer into the season.”

This is useful for the IRCA, which faces challenges each year to repair potholes caused by the repeated freeze thaw cycle during the winter months. According to Helgason, the prolonged seasonal use of emulsion offered by the Roadmaster machine offers additional benefits.

“The Roadmaster allows us to make the aggregate wet in the hopper for better binding, and this also reduces the amount of emulsion needed,” he said.

The sophisticated material delivery system also reduces wear on machine components while the circular surface heating technology is powered by recycling exhaust fumes. This provides a more sustainable option to alternative patching machines, which typically use a front-mounted gas burner to heat the road surface.

“We are impressed with the way material moves through the Roadmaster machine, it allows us to run the truck longer without maintenance,” said Helgason, who hopes to add another of the advanced spray patchers to his fleet in the future. End www.archwayroadmaster.co.uk/

COMPACTING WARM MIX ASPHALT Warm mix asphalts are becoming increasingly important in road construction and offer potential for saving energy and cutting CO2 emissions.

The lower levels of vapour and aerosol are also beneficial in terms of health and safety. However, compacting these types of asphalt means a shorter time frame in which to achieve optimum results.

This is where the latest technology comes in with solutions to support the operator and ensure highquality surfaces.

An effective method for compacting warm mix asphalt is with the proven oscillation system. As the oscillation drum remains in constant contact with the substrate, the compaction rate can be faster. As well as being gentler on materials than the vibration method, oscillation ensures that surface damage is avoided when compacting at lower asphalt temperatures. For compacting asphalt joints, oscillation also prevents damage to areas that have already cooled. Using oscillation increases the time available for compaction before asphalt rigidity increases and becomes difficult to work with.

According to Hamm, another solution for effective compaction of warm mix materials is the firm’s Smart Compact compaction assistant, which controls the compaction energy and compaction modes in both drums on tandem rollers in the HX

series. The system continuously monitors asphalt cooling as well as rigidity values. Smart Compact determines whether compaction should be static, use vibration or oscillation, and also selects the necessary compaction energy. This is said to prevent over-compaction, minimise surface damage and reduce the number of double passes. This increases compaction efficiency and optimises productivity, which adds value for use with warm mix asphalt.

Showing the information from compaction also helps to make effective use of time. Hamm says that its Smart Doc digital solution shows operators compaction values, the number of double passes, asphalt temperatures, and other compaction parameters. Providing comprehensive compaction data allows operators to compact warm mix asphalts more easily, reducing unnecessary double passes, further boosting productivity. Smart Doc can be downloaded free of charge from the Google Play Store.

The firm’s HD 10e and HD 12e battery-powered electric tandem rollers can also be used to compact warm mix asphalts and the company offers variants with an oscillation drum and tyres. These can also be fitted with thermal aprons, which stop the tyres from cooling down. www.hamm.eu

CO2 for asphalt pavements. Improved construction practices can also extend the life of asphalt pavements, while better smoothness reduces vehicle fuel consumption and better scheduling reduces emissions from work zone congestion.

The report offers guidance on implementing pavement design considerations, specifications, and maintenance practices that prioritise sustainability.

These include incentivising the use of materials with lower embodied carbon while allowing contractors to innovate and prioritise maintenance to deliver pavement smoothness and reduce vehicle fuel consumption.

Authors summarise tools available to industry and agencies, such as environmental product declarations (EPDs) and life cycle assessment (LCA) software, that can help quantify GHG emissions and improved decision-making.

“This report details actions asphalt mix producers and laydown contractors can take to reduce the carbon footprint of the pavements we construct while making our businesses better,” said Ron Sines, PE, vice president for Sustainability & Decarbonization at CRH Americas Materials. “It highlights the need to collaborate with owners on project designs and specifications to ensure innovations in materials and processes are employed quickly, maximising their benefits. Most importantly, the report stresses the need to consider the entire asphalt pavement life cycle to ensure the best decisions are made.”

The report’s authors – Director of Sustainable Pavements Joseph Shacat; vice president of Engineering, Research, & Technology Richard Willis, PhD; and WAP Sustainability Director of LCA Technology Ben Ciavola, PhD – emphasise the importance of collaboration between industry, agencies, and academia to advance these strategies.

They also highlight the need for further research to quantify and reduce emissions from asphalt pavements.

APA’s new report, The Carbon Footprint of Asphalt Pavements: A Reference Document for Decarbonization (SIP 109), takes a proactive roadmap for industry and agencies. This can help leverage federal funding in the Infrastructure, Investment, and Jobs Act (IIJA) of 2021, the Inflation Reduction Act (IRA) of 2022, and other programs to reduce greenhouse gas (GHG) emissions.

Heather Dylla, PhD, vice president of Sustainability and Innovation at Construction Partners said: “Coinciding with the recent launch of the FHWA’s Low Carbon Transportation Materials Program Grants, this report emerges as a critical resource for agency engineers and asphalt mix producers. It holds the potential to foster vital discussions and collaborations across the industry, propelling us toward collective sustainability goals.”

With the ambitious goal of achieving net zero GHG emissions by 2050 (articulated in the industry’s The Road Forward initiative), one objective of the report is to identify technologies and practices that can be adopted or expanded to reduce GHG emissions associated with asphalt pavements. Average use of reclaimed asphalt pavement (RAP) in the US remains around 22%, according to data published by NAPA and FHWA. But a mix with 50% RAP can reduce cradle-togate emissions by 29% compared to a mix without any.

The report focuses on actions companies and agencies can take to reduce GHG emissions. The intended audience includes pavement engineers, asphalt mix producers, paving contractors, policymakers, and other stakeholders keen to lower embodied carbon emissions associated with asphalt pavements.

Authors identify major sources of GHG emissions throughout the life cycle of asphalt pavements, including raw material manufacturing, transportation, asphalt mixture production, pavement construction, use of pavements, maintenance and rehabilitation, and end of life.

The report outlines opportunities for asphalt mix producers and paving contractors to reduce GHG emissions. Actions to reduce emissions from asphalt mix production include improving energy efficiency, using cleaner fuels, employing recycled materials and the use of biobased materials that capture and store

ENERGY SAVING WARM MIX

Warm asphalt delivers energy savings and emissions reduction

E

nergy saving is one of the most important drivers for the growing importance of reducedtemperature asphalt in road construction.

Reduced-temperature asphalts are mixes produced at temperatures of 110-130°C. In contrast, conventional hot-mixed asphalts are produced at 140-180°C, typically with hot bitumen at a temperature of 160°C as a binding agent.

Lower energy consumption means fewer emissions, CO2 in particular. According to the German Asphalt Association, a temperature reduction of just 30°C allows a saving of 0.9litres of heating oil/tonne of asphalt. At a daily production rate of 2,000tonnes of mix/day, this can save 1,800litres of oil and reduce CO2 emissions by 6tonnes. Savings achieved in the real world can be higher as the reduction in temperature is often 50°C or more.

The major contribution to energy saving and the reduction of emissions lies in asphalt production. The reduction of bitumen viscosity is a basic requirement for the production of asphalt at lower temperatures.

Benninghoven has developed various solutions to temporarily reduce this viscosity. These include precise metering systems for the addition of liquid and solid additives and the foamed bitumen module.

Mixing hot bitumen with water increases its volume many times over. Due to the surface energy released, the binding agent coats the aggregate efficiently during mixing. Benninghoven’s foamed bitumen module

can be installed as an extension to the weighing and mixing section. It consists of a bitumen pump, an expansion chamber, pipework, injection bars and a water metering system and the module can also be retrofitted to existing plants.

The advantages throughout paving begin before paving work begins. The use of mobile feeders is essential when working with reduced-temperature asphalts due to their ability to offload an entire truckload of mix quickly. With an extra material hopper, it is possible to bunker up to 45tonnes of material on the paver. This enables non-stop paving and allows the broad time window needed when compacting reduced temperature asphalt. Effective conveyor heating also maintains the right temperature of the asphalt mix during transportation to the paver.

In addition, the components of the screed that handles the material are also electrically heated. The use of high-compaction screed technology is another benefit during paving, providing pre-compaction even before the rollers start work. In addition, Vögele has developed the WITOS Paving Plus and RoadScan technologies that assist in the processing of reducedtemperature asphalts.

Site logistics plays an important role for reducedtemperature mixes. Reduced-temperature asphalts in particular become resistant to compaction as viscosity increases, so it is essential to complete the process at the highest possible material temperature.

Lintec plant for Tanzania An asphalt plant from Lintec is being used to supply materials for an important airport project in Tanzania, East Africa. A Chinese contractor, Power Construction Corporation of China (POWERCHINA), selected a Lintec plant for the New Dodoma Msalato International Airport.

POWERCHINA opted for the proven Lintec CSD2500B Containerised Asphalt Mixing Plant for the airport project.

The firm is working on the construction of the new airport for Dodoma, intended to improve connectivity for Tanzania's capital and the wider East African region. The work includes the construction of a 3.6km-long by 60m-wide runway, as well as taxiways, and auxiliary airport roads.

The plant began production in September 2023 at the new airport site in the Masarato district, around 15km from the city centre. The plant is helping to supply materials for key facilities such as a new apron, taxiway, runway, and auxiliary roads. On September 13, 2021, the Tanzanian Government signed a contract to construct the airport investing US$54.74 million into the project, further supported by a $329.47 million loan from the African Development Bank (AfDB).

Construction is taking place in two phases, with the first phase focusing on the runway and terminal. The second phase will be implemented based on demand and once fully operational, the airport will accommodate 1.5 million

passengers/year. The project is on track for completion by April 2025.

A spokesperson from POWERCHINA, said: “Several factors drove our decision to invest in the Lintec CSD2500B Containerised Asphalt Mixing Plant. Firstly, we prioritise safety and reliability in all our operations, and with Lintec & Linnhoff’s German-engineered equipment, we are confident in the highest standards of performance and quality. In addition, the Lintec CSD2500B’s containerised design ensures uninterrupted operations despite Tanzania’s challenging rainy seasons, while its modular construction delivers cost efficiency through low transport expenses and easy installation.”

The Lintec CSD2500B

Containerised Asphalt Mixing Plant is well suited for airport infrastructure construction and the units have featured on other projects including Yap Island International Airport in Micronesia, and Sihanouk International Airport in Cambodia.

Built in ISO certified sea containers, the Lintec Containerised Asphalt Mixing Plants are the first of their kind in the industry, featuring a modular construction that allows for easy transportation and convenient installation. The Lintec CSD2500B model has a capacity of 160tonnes/hour and a batch size of 1650/1600kg.

Additionally, the Lintec Containerised Asphalt Mixing Plants prioritise sustainability with pollution control units and optional recycling systems. The plants are easier to commission due to pre-assembly and testing at the factory. The modular design meanwhile ensures low shipping costs and transportation. In addition, Lintec’s novel double screen drum technology eliminates the need for hot elevator and vibrating screens while reducing the need for maintenance. Combining the heating and screening of the minerals in a single process unit offers the advantage of delivering energy savings.

NEW LOWER CARBON BINDERS DRIVE FURTHER TO NET ZERO Estonian company Fibenol launches its Lignova lignin and Tarmac achieves the lowest carbon resurfacing project yet for National Highways in the UK – Kristina Smith reports

C

leantech company Fibenol has commercially launched its Lignova lignin, produced in a specially designed biorefinery. Lignin – an organic polymer found in plants - can be used to replace a portion of the bitumen in asphalt, reducing its carbon footprint and potentially improving its performance.

Lignova, which is extracted from wood, has already been deployed in trial pavement projects from parking lots to highways in eight countries between 2022 and 2024: Estonia, Latvia, UK, Sweden, Finland, Norway, Ireland and Japan. Fibenol hopes to announce its first ever commercial highways project later this year.

“As most roads are procured by the public sector, the topic of how to reduce carbon and move to net zero is an important one,” said Reet Nõmmoja, sustainable solutions business development manager at Fibenol. “The use of biobinders in asphalt goes hand in hand with the transition away from fossil fuels and chemicals.”

The various trials have replaced between 5% and 25% of bitumen in the asphalt mixes with Lignova, although up to 30% replacement has been achieved in laboratory trials. Lignova is supplied in powder form and added to the mixer at an asphalt plant.

Research by Tallinn University of Technology has shown that for an AC 16 surface course asphalt,

"We convert over 90% of residual wood to Lignova lignin, wood sugars and speciality cellulose - for chemicals and materials industries" Reet Nõmmoja Sustainable solutions business development manager at Fibenol

replacing 10% of the bitumen in the mix with Lignova would lead to a 33% reduction in related carbon emissions up to the point of laying. A 30% replacement would create a carbon negative asphalt mix, with -0.6% of the emissions of a regular AC 16 mix.

Asphalt producers and paving contractors have been experimenting with the use of lignin as a partial bitumen replacement for several years. A test section of road was laid in Zeeland in the Netherlands in 2015 and more recently there have been multiple trials in Finland and in Sweden.

Research has suggested that the addition of lignin could improve the performance of asphalt by increasing its rutting resistance at high temperatures, reducing moisture-induced asphalt degradation and slowing down bitumen ageing due to oxidisation. This is being monitored in real life applications.

Recent trials of Lignova include a section of motorway in Stockholm, Sweden, laid by Svevia as part of its maintenance contract for the Swedish Transport Administration. And Peab Asfalt, which has been carrying out trials with lignin since 2020, laid a 500m test section on a heavily trafficked road in Vantaa, Finland in October last year using Lignova.

Fibenol, in collaboration with research institutions, hopes to conduct research this year which will show that asphalt containing Lignova can be recycled at end

of life. “The circular economy is very important, so we are working with universities and public authorities to show that this can be done,” says Nõmmoja.

Lignova has been successfully used with asphalt mixes containing recycled asphalt planings (RAP).

Other commercially available lignin comes as a by-product of pulp and paper production. Fibenol’s patented biorefining technology, Sunburst, creates lignin which maintains its native lignin structure so that asphalt containing Lignova has no sulfur smell, and instead comes with a natural wood scent, says Nõmmoja .

The Sunburst process takes woodchips made from residual and lower-quality hardwood and converts them to a slurry in just 20 seconds by applying mechanical force, pressure and heat. Enzymes are then used to separate out the lignin, along with hemicellulose (wood sugar) and cellulose. “We convert over 90% of residual wood to Lignova lignin, wood sugars and speciality cellulose - for chemicals and materials industries,” says Nõmmoja.

Fibenol has around 15 research and development projects underway with research institutes, universities and industrial partners, all at different stages. Lignin for asphalt is the most advanced, followed by lignin for resins to be used in plywood and bioplastics.

Other applications under development include the use of wood sugars in insulation and bioplastics, and specialty cellulose - a wood cream or paste - for use in packaging, paints and energy storage.

BITUMEN TECHNOLOGY

Tarmac combines technologies to reach all-time carbon low for National Highways A 2.4km (1.5mile) trial resurfacing project for National Highways on the A64 in Branham, North Yorkshire in the UK (pictured), has reduced its carbon footprint by 75% compared to standard practice by combining lower carbon materials, production technologies and plant.

National Highways says that this is the lowest carbon resurfacing it has achieved to date, without using offsetting.

Tarmac supplied warm mix asphalt from its Cross Green plant in Leeds, which is powered by a combination of biofuel and clean electricity.

The bitumen used in the asphalt mix was supplied by Shell, combining its AgeSafe and Carbon Sink technologies.

The asphalt mixes also

contained recycled asphalt planings (RAP): 37% in the lower layer and 20% in the surface layer. Tarmac deploys shelters to cover its RAP at the asphalt plant, preventing it from getting wet so that less energy is required to dry it out and get it up to the right temperature.

AgeSafe is a polymer modified bitumen (PMB) which contains additives including antioxidants and dispersants designed to inhibit the uptake of oxygen by the binder – which causes the bitumen to harden and become more susceptible to cracking. Carbon Sink sees the addition of a small amount of bio-based binder, which reduces the carbon footprint of asphalt since the plants used sequester carbon as they grow.

Global Highways Magazine for industry related discussion

Carbon Sink 375, which contains 50% more bio binder than the original Carbon Sink C250, was used for this project. Shell developed this next-generation version for Tarmac to use on projects for Hartlepool and Stocktonon-Tees councils in 2023, where Tarmac reports that its combination of low-carbon measures cut carbon emissions

by 80%. Overall, 41.3% of the A64 project’s carbon emissions reduction came from using low carbon raw materials, 14.7% from the transport of materials and the paving process using lower carbon plant, and 44% from manufacturing techniques. Among the plant used were electric and hybrid rollers and an electric bond coat sprayer.

MUON TECHNOLOGY FOR BRIDGES Once the project’s initial research phase is complete, Lynkeos - a spinout from the University of Glasgow in 2016 - will work to bring the updated technology to market for bridges

A

research project using cosmic rays to measure structural integrity of the UK’s transport infrastructure has received a big cash injection from a research council.

David Mahon, a lecturer in nuclear and hadron physics in the University of Glasgow’s School of Physics and Astronomy, has been granted around US$584,000 from the government’s Science and Technology Facilities Council to support the project.

The aim is to reduce the cost and environmental impact of repairs to road and rail bridges by enabling earlier detection of structural problems.

The project is based around Mahon’s work in muography, a technique to measure cosmic rays in order to create detailed 3D images of the interiors of structures.

When the rays collide with the nuclei of the gases found in the planet’s atmosphere, the impact releases particles known as muons. Muons striking objects on earth are deflected very slightly from their course.

The amount of deflection depends on the chemical composition of the object they hit, with heavier elements causing greater deflection.

Measuring the deflection patterns over time, paired with sophisticated computer analysis, allows researchers to build up images of structures. Such images are impossible to produce using other nondestructive techniques including X-rays.

Lynkeos Technology, a spinout from the University of Glasgow in 2016, is already using muography techniques developed by Mahon and his colleagues to help the nuclear industry map the locations of pieces of radioactive waste stored in concrete-filled containers at some of the UK’s nuclear power plants.

Once the project’s initial research phase is complete,

Lynkeos will work to bring the updated technology to market.

Over the next two years, Mahon will work on reducing the size and improving the scanning speed of its muon detector technology to make it more portable and practical for real-world conditions. In partnership with Transport Scotland, the detectors will be tested at a series of bridges across the city of Glasgow.

Mahon said there are more than 74,000 road and rail bridges across the UK, most of which are made from reinforced concrete. Many of which were built between 50 and 60 years ago and so are close to the end of their intended lifespan.

“Current inspection methods often require exposing steel substructure, which can lead to rust and further weakening when exposed to rain, so non-destructive testing methods which allows maintenance crews to see inside,” he said.

“Muography is a technique that’s already proven its worth in the nuclear industry and it seems ideally placed to enable non-destructive testing in transport infrastructure. This grant from the STFC will enable us to build on our previous achievements and build new, more portable test kits that can identify fatigue or defects at a much earlier stage than is currently possible,” he said. “Being aware of problems earlier, before they cause significant damage or disruption, could help bring the overall cost of repairs down.”

In addition to making the muon-detector technology more portable and power-efficient, the project will also find new ways to harness the power of machine learning to speed up the process of taking cosmic ray measurements. End www.lynkeos.co.uk

Vemaventuri, core sensing team up The German companies Vemaventuri and core sensing have entered into a partnership to drive digitalisation on the construction site.

Vemaventuri and core sensing will pool their expertise and jointly develop new products for the digitalisation of the construction site. By combining the strengths of both companies, innovative solutions will be created that will change the construction industry in the long term.

Vemaventuri, a wholly owned subsidiary of Peri, also based in Germany, specialises in solutions for monitoring and optimising concreting processes and increasing the efficiency of construction site workflows. By integrating sensor technology, the company said it can enable precise data acquisition and evaluation. This ensures greater safety and control on the construction site and makes a significant contribution to increasing efficiency.

Meanwhile, core sensing said it transforms mechanical components into intelligent, wireless sensor systems. With its intelligent and integrated sensor solutions, the company said that it is setting new standards in Industry 4.0, a term used to describe the current era of embedded connectivity, the ubiquity of technology in society that changes the ways humans experience and know the world around them.

In close partnership with customers from the construction, mining and production machinery sectors, among others, core sensing offers full-stack solutions. Full-stack development is the process of developing both the frontend (user-facing) and backend (database and logic) of applications. Its solutions make it possible to use real time data from machines and systems to increase efficiency in terms of condition monitoring, reduce maintenance costs and develop new digital business models.

“We are very pleased about the partnership with core sensing,” said Michel Seeger, managing director of Vemaventuri.

“Together, we can significantly advance digitalisation on construction sites and offer our customers innovative solutions for greater efficiency and safety.”

“The collaboration with Vemaventuri gives us the opportunity to use our sensor technologies in a new field of application,” said Christoph Miks, director of customer solutions at core sensing. “Together, we have already reached important milestones and I am convinced that we will develop forwardlooking and sustainable solutions that will set new standards in the industry and decisively advance digitalisation on construction sites.”

Vemaventuri and core sensing will be presenting their jointly developed solution at bauma, the international construction equipment show in Munich, Germany, April 7-13.

istler said that when the installation is completed, the smallest state in the US will have the largest digital weigh-in-motion (WiM) site in the world, with 40 Lineas digital quartz sensors covering 10 traffic lanes.

Providence is one of the few cities in the US that is proactively using advanced technology. The north span of the Washington Bridge is being removed and a new span is planned. To keep traffic moving during the north span restoration, two traffic lanes were added to the south span.

The load rating on the south span is adequate, with the installation of structural health monitoring solutions from Kistler, the department of transportation can evaluate the health of the south span in real-time to assess any potential adverse impact from the additional traffic load and enable proactive mitigation of variations in its structural health.

Comprehensive sensor-based structural health solutions from Kistler offer real-time data for bridge structural condition monitoring to enable the Rhode Island DoT to perform predictive analyses and more timely preventative maintenance. Included is a customised Kistler digital WiM system to provide real-time evaluation and monitoring of precise bridge traffic load, as that information impacts the structural health of each bridge.

GLOBAL HIGHWAYS 2025 VOL. 1

Kistler will outfit the bridge with measuring equipment - accelerometers, strain gauges, temperature sensors, inclinometers and a meteorology station - to measure, collect and interpret bridge health data. A WiM system will monitor specific load conditions.

For the structural health monitoring system, all hardware will be installed on the bridge based on engineers’ assessment of structures most likely to experience strain.

For example, while a bridge was built to vibrate and move, accelerometers can measure just how much and whether the movements are within the normal range specified for that structure. If undue stress is detected by the sensors in real time, the department of transport team can implement measures to preserve the bridge’s structural integrity and health.

The WiM system includes Lineas digital quartz sensors from Kistler placed just under the surface of the bridge’s roadway as well as charge amplifiers to condition electrical signals from the sensors and data loggers to process data in real time. LPR (licence plate recognition) cameras are positioned to identify trucks by their class size and monitor for overweight wheel, axle and gross vehicle weight (GVW) loads.

Importantly, the Kistler monitoring and WiM systems are connected to share critical data and paint a picture of the bridge’s overall structural health in real time. With this integrated data, bridge engineers and analysts can work with data on exact loads, axle weights and truck class to monitor the weight of trucks going across the bridge, as well as multiple measurements that assess the loads on the bridge structure to assess predictive maintenance requirements or be alerted to the need for emergency repairs.

HYDROGEN POWER

Hydrogen as a fuel for internal combustion engines is coming closer for the off-highway machinery sector

T

his clean fuel may well be used for applications where emissions have to be strictly controlled.

But it may be some time before hydrogen is at a price where it can be used more widely for construction rather than specific duties.

Various firms have been working on internal combustion engines able to run on hydrogen. Progress has been rapid in the sector.

Cummins is working on the UK Governmentfunded Project Unity in partnership with Holtex and the University of Manchester. The project is developing sophisticated digital technology that will enable optimised design of componentry for hydrogenfuelled engines.

Cummins is leading the project, which has £2.4 million of backing from the UK Government from a facility at Huddersfield in the UK. The aim of the project is to utilise machine-learning tools to analyse how key components will perform in use under load and over a long period, determining when or how they could fail. The use of machine learning will reduce the amount of physical testing needing to be carried out, speeding the development of reliable components.

Data will be collected on the performance of components such as turbochargers and bearings operating under high loads and at high speeds.

The sophisticated simulations can then provide information to optimise component specifications. The programme will investigate components used in both internal combustion engines and fuel cell stacks.

The Advanced Propulsion Centre UK (APC)’s Collaborative Research and Development funding round, APC25 provided the funding in partnership with Innovate UK, a part of UK Research & Innovation.

The UK Government has invested in a series of Global Highways Magazine for industry related discussion

ABOVE JCB has been awarded approval for its hydrogen engines to be used in construction machines BELOW Cummins is investing in research into clean power technologies for the future

technologies that will boost the development of green transport and power solutions.

This development represents a marked change from the conventional process of using actual testing to determine component durability and reliability over time. The machine learning will focus on failure modes such as hydrogen effects, water droplet erosion, and structural integrity.

This project will help speed the transition from diesel ICE to hydrogen powertrains in both onhighway and off-highway applications.

Meanwhile, JCB has secured a ruling from licensing authorities allowing its hydrogen-fuelled engine to be used commercially in machines. The company says that 11 licensing authorities across Europe have given permission for the hydrogen engine to be sold across Europe, with authorities in other countries set to follow suit.

The Netherlands’ Vehicle Authority RDW was first to provide certification. Other European bodies followed, including Great Britain, Northern Ireland, Germany, France, Spain, Belgium, Poland, Finland, Switzerland and Lichtenstein.

This makes JCB well placed to win orders for off-highway machines fuelled by hydrogen for use on sites where there are restrictions on emissions. The Lower Thames Crossing project in the UK has specified that there will be no diesel machines onsite and that mobile equipment will have to be electric or hydrogen-fuelled.

JCB has produced over 130 hydrogen evaluation engines which are powering backhoe loaders, telehandlers and generators, with testing on customer sites at an advanced stage. End www.cummins.com www.jcb.com GLOBAL HIGHWAYS 2025 VOL. 1

ICY WEATHER

Seatbelt use is banned on safety grounds for drivers using Europe’s longest ice road stretches 27km and is in Estonia, linking the port of Rohuküla on the Baltic Coast with Hiiumaa Island. This seasonal road is used in winter by cars and trucks to access the island, with seatbelt used banned in the event of people having to get out of their vehicles quickly should the ice give way. Drivers are told to travel either at speeds below 25km/h or at speeds from 4068km/h, to prevent resonances that could break the ice. The speed limits are enforced very strictly for safety purposes

QUICK THINKING

A child managed to take control of the family car when his grandfather fell into a diabetic coma while driving along I-75 in the US state of Georgia. The 10-year-old child managed to grab the wheel and bring the car, which was towing a boat, to a safe halt in the hard shoulder. The child then called the emergency services for assistance, saying his grandfather was in a diabetic

coma. Police and paramedics rushed to the scene and were able to give the man an IV to stabilise him, while officers were able to move the vehicle, and the boy's mother was able to collect him and take him home.

Although the man usually wore a device on his wrist to alert him when his blood sugar levels fell too low, this had broken and he had called his doctor to provide a new one. Officers were so impressed with the boy’s response that they provided him with an award for his smart thinking.

SEND HELP

A British woman resorted to appealing on social media for help after her husband and son decided to play a prank on her.

They set up a function on her Tesla car so that it would make a farting noise every time she left the vehicle and the self-locking mechanism activated. She did not know how to change the setting. The husband and son meanwhile were highly amused and refused to disable the setting resulting in the woman having to seek assistance elsewhere.

A CLOSE CALL

A woman in Australia had a lucky escape recently when the car she was travelling in crashed.

The car was being driven very quickly, with the driver swerving around other vehicles on a stretch of highway. However, the driver lost control and rammed into the barrier wall. The woman was not wearing a seatbelt and was flung from the vehicle by the force of the impact. Incredibly, she suffered only minor injuries.

DRUNK AT THE WHEEL

A man in Scotland was caught by police with a blood alcohol level almost seven times the legal limit. He had fallen asleep at the wheel of his car after

consuming a bottle of gin when he was discovered by police, which resulted in the A9 road having to be closed temporarily.

However, when he appeared in court on the charge of drinkdriving he appealed against the mandatory ban, saying that he has health issues and because it is 1.5km to the nearest bus stop, the usual mandatory ban for the offence would be difficult to cope with.

WHO ATE ALL THE PIES?

A truck containing pies was stolen in the UK recently.

After a search by police, the missing vehicle was located and recovered. However the pies were missing. It is not clear if police have been looking for thieves suffering from indigestion.

To those thinking electric cars are new, think again. In fact, the first six World Land Speed Records set by cars were all made by electric vehicles in the short period between 1898 and 1899, the last of these being made (most famously) by Camille Jenatzy when his torpedoshaped vehicle managed to top 105km/h. The next speed record was set by a steam-powered car and it was not until 1902 that a Mors car with an internal combustion engine and driven by William Vanderbilt was able to seize the eighth World Land Speed Record at 120km/h.

Efficient recycling A new mobile impact crusher. MOBIREX MR 100i NEO from Kleeman, is being used

by E+F Recycling at a site in Nordhorn in Germany for recycling concrete and rubble.

The unit is said to feature a robust design and versatility as well as a compact design that means it can also be used in tight spaces. A new feature of the plant is ‘Lock & Turn Quick Access’. This system enables the quick and tool-free opening of the crusher housing. Opening and closing only takes 30 seconds and simplifies access for maintenance, when jams need to be cleared or impact bars replaced. Safety and efficiency during operation are also improved.

Another highlight of the MR 100i NEO is the fully hydraulic gap adjustment and overload system. The gap adjustment as well as the zero point determination can be set accurately from the control panel.

This means that manual measurement, loosening screws and the ultimate positioning are not necessary.

DEVELON ADT ADDITION Cross Civils & Construction Services, based in Aberfeldy in Perthshire, Scotland has purchased a new Develon DA30-7 articulated dump truck (ADT). The new ADT is the first from Develon at the company and was supplied by Castle Douglas-based James Gordon (Gordons), the new Authorised Dealer for the whole of Scotland for Develon, formerly Doosan Construction Equipment.

Kevin Cross, the owner of Cross Civils & Construction Services, commented: “David Moir at Gordons, who I’ve known for a long time invited me over to try out the Develon DA30-7 ADT as a possible replacement for one of the machines in our fleet. David and Gordons showed impressive attention to detail and understanding of our business needs, to ensure a very quick turnaround from placing the order to delivery of the new machine.

“I was convinced about the DA30-7 right from the start. It has a shorter turning circle and is very stable, with a lower centre of gravity compared to other

machines of its size on the market. The permanent six-wheel contact and drive offers excellent performance on all the surfaces we have to work on, such as soft ground, uneven surfaces, steep slopes, tight turns or a combination of all of these difficult conditions.

“Due to work demands, the Develon DA30-7 became an addition rather than a replacement and brings the number of different brands in our fleet to four".

The overload system ensures that the machine is protected against damage from uncrushable material such as tramp metal.

When triggered, the pressure plate breaks so that the rocker arm can get out of the way. This protects the rotor, the rocker arm and the crusher housing. The pressure plate can be replaced by the operator onsite, which is cheaper than damaging the rocker arm or crusher.

The operation of the plant is userfriendly due to sophisticated functions such as the crushing gap setting and troubleshooting tools. In the future, the system will allow production data from the belt weigher to be viewed remotely.

www.wirtgen-group.com

"We utilise the DA30-7 in every part of our business, from our civils and housing development projects to working in our own quarry, where we produce sand and gravel.”

“Without doubt, the DA30-7 has proved itself to be the best machine we have and this is strongly supported by the two drivers who normally operate the machine between them.“ eu.develon-ce.com/en/

RECYCLING

RECYCLING FOR CARBON SAVING

A new approach to procurement for road construction is driving a change to recycled materials and allowing savings on carbon emissions as well as cost. The partnership between Huyton Asphalt and Tarmac is delivering new solutions for clients in the UK

A

ccording to Liam Brown, commercial director at Huyton Asphalt, the road sector is seeing a growth in sustainability across the industry: “Price and quality are still part of procurement criteria but the importance of carbon saving and the ability to provide customers with new innovation and data-led guidance about materials is on the rise.”

In 2008 Huyton Asphalt formed a partnership with Tarmac that has become peer-to-peer collaboration focused on material innovation and data-led reporting.

Megan Thompson, technical product support manager at Tarmac said: “Being able to identify and offer clients value-added solutions that move beyond a ‘tick-box’ criteria for sustainability has underpinned the partnership between Tarmac and Huyton Asphalt.

Huyton Asphalt has rolled out its Innovation Halo range of low carbon materials for its customers, which have been developed by Tarmac and include warm mix asphalt and surfacing products that use rubber from recycled tyres.

For one project, Huyton Asphalt delivered a major surfacing project in Deeside, North Wales involving over 17,000m2 of carriageway resurfacing. Over 9,000tonnes of Halo warm mix and 1,600tonnes of Halo Rubberpave was installed, including more than 2,600tonnes of recycled asphalt pavement (RAP).

Using these materials, the team delivered a carbon saving of 57.3tonnes – a 13% reduction in emissions.

James Blennerhassett, managing director at Huyton Asphalt said: “Requiring less energy for production and application, warm mix asphalt reduces carbon emissions whilst maintaining quality and durability.

It is typically produced at 20-40˚C lower than hot asphalt, reducing the embodied carbon of the material by 8-12%.

"Being able to identify and offer clients valueadded solutions that move beyond a ‘tick-box’ criteria for sustainability has underpinned the partnership between Tarmac and Huyton Asphalt"

Warm mix has become a default product for Huyton Asphalt’s customers, but the technology is also being applied to other new innovations and environmentally sustainable asphalts. The company’s BBA approved Halo RubberPave material is helping to repurpose and recycle the rubber from end-oflife tyres (ELT) into the UK’s roads, contributing to a circular economy.

When combined with warm mix technology, it has been calculated to deliver an average saving of 3.5kg of CO2e/tonne compared to conventional asphalt.

Thompson commented: “For every kilometre of highway surfaced, rubber asphalt can reuse the

RECYCLING rubber of up to 750 waste tyres, helping to reduce the 120,000tonnes of rubber waste, including 500,000 tyres, that are exported from the UK annually.

“The end material is a durable, high-performance asphalt using SMA technology that’s suitable for most locations.”

The partners are now looking to understand how new materials can bring opportunities to build carbon sinks into roads. Developed by Tarmac and championed by Huyton Asphalt, biogenic asphalt binder technology locks away carbon absorbed during the growth of the biomass element, turning the road into a carbon sink.

Since the asphalt can be recycled at the end of the pavement life, most of this carbon will not re-enter the atmosphere. According to available data, biogenic asphalt technology could reduce the carbon footprint of an asphalt mix by up to 40%.

Ian Carr, regional technical manager at Tarmac said: “Our close collaboration has also allowed us to look beyond asphalt too. Low carbon concrete is increasingly popular due to its sustainability credentials – in this instance it has achieved a 49.1% reduction in carbon emissions while maintaining the durability, strength and resilience of traditional concrete.”

THE HIGH LIFE FROM HILIGHTS Atlas Copco says the second generation of its solar light towers, the HiLight MS 4 and MS 5, significantly reduce carbon footprint

T

he recently launched new models of the HiLight MS series are more compact than the first generation of Atlas Copco solar light towers due to the solar panel design, explained Eric Tomin, product marketing manager for Atlas Copco’s Power and Flow division. They are brighter thanks to the SMD High Lumen LED technology and offers more autonomy and reliability with solar panels in parallel. If one panel has an issue, the battery continues to be recharged by the others. Each solar panel is equipped with one Maximum Power Point Tracking (MPPT) for efficiency and the units are protected by a robust HardHat canopy.

The loading capacity is optimised to fit nine units in a 40-foot High Cube container.

Atlas Copco’s HiLight MS 4 and MS 5 offer light coverage of up to 3,846m² and 5,278m² at an average of 20 lux, with surfacemounted device (SMD) High Lumen LED lights providing 87,750 lumens from the MS 4 and 117,000 lumens from the MS 5.

With an increase in light coverage by 20% compared to traditional chip-on-board (COB) LED types, the superior lumen per watt ratio achieved by these light towers means that they offer greater lighting distribution and efficiency. Moreover, a 5kWh lithium battery contributes to up to 85 hours of autonomy with a dimming function and ECO mode that with a dedicated control

cubicle. The lithium batteries and solar panels deliver a minimum of 11 hours of autonomy, with recharging times as low as four hours for the MS 4 (with one battery) and five hours for the MS 5.

Recharging time can be significantly reduced to up to 2 hours and 36 minutes if the recharging is by solar panel with full sunshine, depending on the model.

Moreover, both models feature remote monitoring capabilities to help contribute to increased safety and productivity. They can operate in extreme temperatures, ranging from -20°C to 45°C. Safety and convenience are enhanced with features such as an E-winch, Earth Leakage Relay, E-stop and Photocell and AutoStart. Additional options include EU Road Homologation, AUS undercarriage version, and C5M painting.

Portable Power and Flow is a division within the Power Technique business of the Atlas Copco Group, and part of the Power Technique Business Area. Its mobile generators, energy storage systems, light towers and portable and industrial pumps, serve a wide range of industries such as construction, mining, wastewater and biogas.

VERSATILE COMPACT MACHINES FROM WACKER NEUSON Wacker Neuson is now offering new additions to its range of compact construction machines. The new compact WL250 and WL750 wheeled loaders are claimed to offer more efficiency and comfort.

These are the first models with the new nomenclature for the firm’s wheeled loaders. The bucket size can be determined by the product designation, with WL250 referring to a volume of 0.25m3.

The WL250 wheeled loader has an operating weight of around 2tonnes and has an overall height of less than 2m, suiting it for construction applications in restricted spaces. The machine is said to feature a robust design and a low centre of gravity for stability when carrying heavy loads. The WL250 features direct hydrostatic drive for all four wheels.

Rear visibility is said to be good due to the panoramic rear windshield, which increases safety. The machine has an electronically-governed drive system with several operating modes to suit a range of duties.

The new TH625 is a compact telehandler said to offer high efficiency in use, featuring a high payload for its class at 2.5tonnes, combined with a lifting height of 6m. It is offered with a choice of engines delivering 45kW or 55kW, as well as featuring fast and high material handling.

Due to its compact dimensions and good manoeuvrability, it can also be used in confined spaces. The cabin is

ergonomically designed and offers good all-round visibility for safety and efficiency.

The electronically-governed drive system benefits from several operating modes to suit an array of working duties.

Like all Wacker Neuson telehandlers, the TH625 is also equipped with the driver assistance system Vertical Lift System (VLS).

The system prevents the machine from tipping in the longitudinal direction due to overload, boosting operating safety even with high payloads. It ensures greater safety on the construction site and also greater efficiency and ease of use. www.wackerneuson.com

The new WL750 wheeled loader has an operating weight of around 4tonnes and is said to be highly manoeuvrable.

Versatility is optimised due to the quick-change plate, which also maximises visibility. The WL750 benefits from a new cab with wider access, more legroom and ergonomic controls.

More efficient pile cropping National Pile Cropper (NPC) is introducing an upgrade to its Heavy Duty CFA Links to cope with the most demanding of projects.

This has been developed following customer feedback. For dealing with augured (round) piles, NPC developed the CFA & HD range, which cuts circular augured concrete piles ranging from 300mm to 2,000mm in diameter.

Specifically in response to meet customer demands, the latest version of the NPC Heavy Duty CFA Links have a new and improved design to help achieve minimal downtime for working to demanding timescales, in challenging conditions. Since their introduction, they have become the go-to option for the reduction of larger diameter piles, being able to crop piles up to and above 2m in diameter. The firm says that the NPC Heavy Duty CFA Links are larger than other croppers available. They provide more of

the desired cropping power customers now require. This means that they are able to reduce piles of 2m in diameter, such as those found on large highways projects.

The firm says it also offers segmental adjustment links to help provide a closer proximity to the pile.

This enables the shape tuned chisels to penetrate and provide the necessary break.

The units are modular in design, which is said to ensure versatility and allows them to be adjusted to suit required pile sizes with adjustments of 100mm at a time without any hydraulic interference. In addition, by using the provided lifting frame, restrictions are minimised.
