Embrace Technology or Fall Behind

W

ith innovations like telematics, robotics, automation and drones, along with data to improve design and project management, the construction industry would seem to be the perfect storm for propelling a technological revolution forward.

However, a 2017 survey conducted by KPMG found that while 72% of the engineering and construction executives surveyed stated technological innovation played a role in their company vision, less than half had a clear strategy in place to integrate those advancements.

In addition to a lack of vision, only 5% of respondents considered themselves on the forefront of embracing these advancements with the majority of people indicating they were industry followers instead of leaders.

Throughout the past few years, we’ve covered technology advancements in the industry and are always looking to show contractors how embracing this technology can help them improve their business and their bottom line.

Still respondents of that same survey indicated the construction industry will need more than five years to fully embrace technology. Why the continual resistance to change?

Just last month we covered variable depth paving and how embracing this technology saves both time and money. We even had the data to prove it, referencing a company that was going to incur liquidated damage costs of $240,000 for every day they went over on an airport project. Had they not used 3D, they would have missed the deadline by 10 days, costing them over $2.4 million. Ouch.

With the technology, they were actually able to finish three days early and since they knew exactly the amount of material they were going to be placing, they used 1,000 tons less material and put all those production and material cost saving right back in their pocket.

MILLENNIAL MINDSET Along with helping to save you money and improve your business, embracing technology has been a proven way to attract the younger generation of workers to the industry.

They have grown up with apps and solutions to solve just about any system problem that arises. As the industry ages, we will have to embrace more innovation in order to entice and appeal to younger workers.

Embracing the Millennial mindset is another way we can attract the younger generation to work in construction as they want to add value, make an impact and find meaning in what they're doing. What’s more rewarding than turning piles of dirt into roads?

Check out the technology special report in this issue to see some of the emerging technologies that Millennials appear to be comfortable with. We do a deep dive on using drones for aggregate management but some other ideas of products/services you might consider implementing on the jobsite could include smartphone apps, tablets, wearables and more.

We are always working to investigate ways contractors can leverage new technology to improve their business and are continually looking to work with contractors on new articles. As always, please contact me at jlombardo@acbusinessmedia.com if you have had success implementing technology on the jobsite and are willing to share your story.

Don’t fall behind your competition.

Embrace the change now or risk losing your next bid to a company that can guarantee job completion on time and on budget with their tried and true technology.

DRONES Improve Aggregate Management

Asphalt plants can benefit from investing in these tools to help measure stockpiles and more

their plant operations and beyond. At the asphalt plant, drones are primarily used for quantities measurement, site preparation and inspections and using them can help save contractors an exceptional amount of time and money.

U

MATERIAL MONITORING As plant owners know, the various materials and aggregate in asphalt are considered inventory that have a monetary value attached to them.

Measuring the volume of stockpiles accurately is key in determining the value of the material. A drone can be used to fly over the stockpiles to collect aerial

imagery from which accurate quantities can be measured.

“Accurate material inventory allows asphalt companies to properly serve their customer orders, as well as improve a steady state for production level-based demand,” Jason Nichols, product marketing manager at Kespry says.

“Traditional survey methods used to measure inventory are often inaccurate, time-consuming and dangerous. Drone technology is up to 80% more accurate than traditional survey methods and removes workers form active and dangerous environments. Using an end-to-end commercial drone solution,

done in a half hour in the file, then the measurements taken in the office from a computer.”

Nichols says surveying with a drone is a fairly straightforward process that has three main steps. First is mission planning, which is typically completed on an iPad where the area to be surveyed is outlined by drawing a polygon. Second is automated flight and data upload.

The drone flies to complete the mission outlined in the first step and then automatically transfers the data to the cloud. The last step is data processing and analysis. Once the data has been automatically processed, customers are able to perform a complete inventory analysis within hours of the flight.

“A typical site of approximately 30 acres can be flown in less than 30 minutes,” Nichols says. “This same site using traditional methods could take an entire day or more. The hours of labor saved can be an accumulation of both time saved in the field as well as time saved not processing raw data.

companies are flying as often as needed, reducing labor costs and ensuring annual write downs are reduced by 95%.”

Currently, there are several traditional survey methods used to measure stockpiles each of these methods involve a substantial amount of labor hours to physically walk the site and use the equipment to measure each pile.

“Quarry and stockpile management are done today by all sorts of methods including flyovers by manned aircraft, GPS topo surveys, laser scanners and perhaps the most common – stepping it off,” Chase Fly, geospatial product manager with Delair says. “Each method has its tradeoff whether it be too expensive, time-consuming, dangerous, or inaccurate. A groundbased survey may take several hours or even days, while a drone could be

more frequently than a manual process allowing companies to see real-time changes in inventories and balance them to production levels, giving operation and sales teams the ability to better fill orders and forecast. Kespry customers have found an 84% reduction in labor costs when measuring stockpiles across multiple sites.”

Reduced labor costs aren’t the only reason to invest in a drone.

“Using a drone also keeps your people safer since they do not have to be on piles or out on site around heavy machinery,” Fly adds. “Cost savings can also be significant, even thousands

DRONE DECISION MAKING Deciding which drone to buy can be a daunting task. Make sure you do your research to see what model will best suit your needs.

of dollars per survey. And the accuracy can improve as well since a drone survey provides a much higher density of points than traditional ground based surveys.”

Once the area is surveyed, the data gets uploaded to the computer for accurate mapping.

"Photos are taken throughout the flight and these photos are later imported into a computer program where they will be “stitched” together to create one big aerial map of the entire site," Fly says. "Layers generally consist of a digital surface model (DSM), a point cloud and an orthophoto. The DSM or point cloud can then be used to measure the volume by simply drawing a polygon around the base of the pile."

"There are key questions to ask before making a purchase," Nichols says. "Is the drone made for it the harsh nature of an asphalt plant environment?

How often would you like to perform inventories? What data packages are available for daily flights? Can you grow with the drone and software technology?

Are you confident it will evolve to meet your needs?"

"A contractor in this industry really needs a drone that is optimized for mapping and aerial survey," Fly adds. "Multirotor drones will serve some needs such as visual or video inspections of equipment and surveys of small sites, while a professional fixed wing mapping drone will cover more

Get Legal Once you’ve bought your drone, you need to take the necessary steps to operate it legally and that means obtaining the required permits and registrations.

“First steps to start using a drone on a site depends on the type of drone solution that’s chosen,” Nichols with Kespry says. “Regardless of the platform, each drone will have to be registered with the FAA under the Part 107 rule and the person who will perform the flight needs to be obtain a Part 107 remote pilot airman certificate.

Aviation liability insurance is recommended and can be obtained through specialized insurance carriers.

Complete drone solutions provide aviation liability insurance as part of the subscription and will register each drone for the customer, as well as provide all the necessary training material and lessons to prepare them for the Part 107 test.”

“There exist many other rules such as not flying higher than 400 feet above ground, only flying in approved airspace, keeping the drone within visual line of sight at all times, and not flying at night or over people, to name a few,” Fly with Delair adds. “Waivers may be requested and are reviewed by the FAA on a case by case basis. In addition, there may be state or local laws that regulate where and how drones can be used, especially as it relates to privacy and operating around the public.”

ground in less time and integrate PPK GNSS technology for high-accuracy measurements that are repeatable."

"There are a lot of choices these days. It’s best to know what you’re trying to achieve with a drone solution," Nichols says. "Several factors should be considered when conducting research, including levels of accuracy, ease of use, customer support and data analysis and integration. Several packages are available on the market and can come in a variety of options."

OTHER USES FOR DRONES In addition to mapping your stockpiles, drones can also be useful to safely monitor problems at your asphalt plant.

"Drones are capable of detecting temperature changes, gas leaks or damage using a combination of specialized sensors and artificial intelligence to

detect and identify potential plant problems," Nichols says. "The technology is becoming more readily available in the commercial drone space and will be more common as demand drives this next phase of development."

"An aerial view of an asphalt plant can give a site manager a way to monitor what is happening on site from a perspective he would not have otherwise," Fly adds. "Photos and videos from a drone can be used not only to do quick visual inspections, but to create 3D models of a site and all the infrastructure on it for closer inspection, hazard analysis and more."

Having a drone can also help you with site management as well.

"An asphalt plant may need to do some earth work to prepare a site for stocking, loading, or hauling material," Fly says. "Drones can be used to conduct an accurate survey of the ground to help determine the

most efficient way to prepare the surface for inventory or construction of machinery."

A drone can help an asphalt plant be more efficient, accurate and safe in their stockpile measurements and site surveys. In addition, it can also provide a more thorough inspection of plant facilities which will enable problems to be caught sooner and maintenance to be done more effectively.

Regardless of what drone you choose, make sure you work with an authorized distributor partner to make sure you get the necessary training, certifications (see “Get Legal” sidebar) and support you need to successfully operate your drone.

New Construction Technologies Pose NEW RISKS While technologies like the Internet of Things and wearable devices can improve construction activities, they also pose cyber risks to protecting these “borderless” job sites

T

echnology has expanded the way we work. We can now share data instantaneously, which both improves our productivity and expands the challenges we deal with daily.

With the steady progression of the Internet of Things (IoT) and other technologies, job practices such as virtual design and the virtual sharing of plans are becoming the norm. As construction companies increasingly incorporate and rely on new technology, job site risks are expanding.

This means there are risks that can’t be seen at the physical location — such as cyber risks — hence the term borderless job site.

With these new challenges, it’s more important than ever for risk managers to broaden their thinking around risks and develop a plan that protects both its physical and digital presence.

UNSEEN RISKS Where has technology infiltrated your jobsite? That is what contractors need to think about when investigating potential cyber risks.

Virtual design and project mapping is allowing more collaboration in a faster way. Using technology, partners can conveniently work together from any location on the design elements for a project long before construction begins.

However, because information is stored digitally, it can be vulnerable to hackers.

18

“To help contractors protect sensitive information, we suggest limiting the number of employees and partners who can access the material, making sure passwords are strong and secure, implementing a multitier sign-on process and establishing a backup kept at a different location that tracks changes to documents,” Bob Kreuzer, vice president, risk control at Travelers Insurance says Many job sites and buildings also have technology that enables off-site users to turn on lights, control temperatures and utilize water sensors and alarm systems.

This can pose potential threats as well.

“During the construction phase, there are many people coming in and out of the site, which could create an opportunity for tampering (for example, disabling smoke alarms or heating systems),” Kreuzer says. “These technologies may also be vulnerable to hacking after completion of a project.”

THREATS FROM WEARABLE TECH When used properly, wearable technology can help improve the quality of work and the safety of employees on

construction sites, but if a company is investigating wearable technology, there are additional risks to consider.

“We are starting to see contractors test different types of devices like smart glasses or proximity sensors,” Kreuzer says.

“Before using any of these new wearable tools, it’s important to train everyone who may be using them so they understand how these tools work, how they can benefit them and how to avoid problems that can arise while they are in use.

“In some cases, there might be a less experienced employee on-site wearing this technology and doing the work with a more experienced person in an office watching remotely and providing recommendations and instructions. While this is certainly convenient, the person in the

SPECIAL REPORT: TECHNOLOGY office isn’t experiencing the tasks with all senses, which might make giving advice or direction riskier.

“And like other forms of technology, wearable devices can also be vulnerable to hacking or malfunctions. We are working with our construction customers to test a variety of wearable devices, and with that work, we hope to not only identify wearable devices that can reduce the risk of injury but also better understand the settings where they could have the greatest impact on safety.”

While all of the potential risks associated with using wearables on the job site are still largely unknown, they could involve risk of a cyber-attack, creating a false sense of security leading to bodily injury or the technology may not be able to sustain certain construction environment challenges.

“In regards to cyber risks, if information is not properly secured and a breach occurs, sensitive information may be in jeopardy,” Kreuzer adds. “It is important to keep virtually stored information safe and protected.

It’s also a good idea for businesses to make sure they are working with someone that has cyber expertise to help implement other controls as well.”

PREVENTING A BREACH It is clear there are many risks associated with technology, so how can a construction contractor counteract these potential risks?

Business decision-makers need a strong understanding of what their cyber risks are and how they can be managed. This will allow them to communicate dangers with employees and fully integrate the company and its employees in behaviors that help limit risks.

Every company is different, but members of a business’s leadership team are typically involved in creating these steps.

20

Involve the IT department in the decision-making on how to help protect the company and in planning business strategies to protect from potential cyberattacks, but do not leave decisionmaking solely to them.

“Knowing what steps to follow after a breach is crucial and can help minimize the damage,” Tim Francis, enterprise cyber lead at Travelers Insurance says. “Having a plan in place before an incident occurs, and updating that plan as needed, is key. However, that plan won’t be any good if employees aren’t aware of the risks and informed of safety protocols, so educating them is just as critical.”

Creating the proper safeguards — such as the use of firewalls, antivirus technology and intrusion detection systems — can help prevent an attack from happening, but breaches can occur even with preventive measures in place. Companies would benefit from also having systems in place in the event something does happen. This can include insurance policies to manage financial risks and a crisis communications plan for internal and external parties.

While technology can be a great thing, it also has the potential to be detrimental to a business. Maybe now is a good time to talk to an insurance agent or someone who offers risk management services about your company’s potential exposures and how to best address them.

For more tips on how to prevent cyber attacks, visit ForConstructionPros. com/21004396.

Don’t Forget Traditional Risks While cyber risks are a new concern for contractors, it’s important to remember that more traditional risks — public safety, fire, water and theft — are still a major threat for businesses.

“In our view, those will likely always be at the top of the list to consider when it comes to keeping the job site safe and secure,” Kreuzer says. “We still see losses resulting from fire, water and theft around the country. Because many of these issues can be prevented if proper safety precautions are taken, it’s critical for managers to provide new employees with an overview of physical work site threats, as well as the proper protocol for addressing them.”

Buildings under construction face a higher risk of fire, such as from hot work or allowing smoking within the building, and many of these buildings do not have the full fire-suppression systems (sprinkler systems) in place. Other causes of fire include the use of torches for cutting, soldering, roof work, blazing and welding.

A written plan that includes operations management and fire protocols should be implemented and strictly enforced.

“Recently, we have seen contractors activate the fire-suppression systems as the building progresses, providing increased fire protection earlier in the construction sequence,” Kreuzer says. “This type of proactive approach can set contractors apart from those that are following more traditional, and what I would call basic, protections.”

When it comes to water damage, conducting regular quality-control testing and periodic inspections of the work and the materials will help reduce the likelihood of an incident, such as a burst pipe.

Lastly, theft, vandalism and unauthorized physical entry are still major risks on the job.

Thieves often target sites with materials they can quickly sell. Establishing barriers to prevent access to the job site is one common defense. This can be done by installing full-perimeter fencing, locked gates and interior/exterior lighting. Intrusion detection systems, such as motion detectors at gates and other points of entry, are great tools to help businesses stay aware of what’s happening on-site.

S.T. Wooten Invests in

Upgrades

Henderson plant location installed a new drum, updated its dust collector and added a third silo to boost productivity

F

ounded in 1952, S.T. Wooten serves North Carolina in the asphalt materials and ready-mix concrete markets, as well as with heavy highway, design-build and commercial site work.

With over 900 employees, the company knows the value of investing in their people and facilities in order to remain competitive. For the past few years, much of the asphalt being produced at their Henderson, NC plant has gone to the Interstate 85 project. The project involves paving a 20-mile section of the interstate to improve road conditions from Vance County to the Virginia state line.

In order to boost production at this facility and keep up with mix demand, last winter S.T. Wooten installed a new

drum, updated its dust collector and added a third silo to boost productivity.

“The updates have allowed us to save time and boost productivity at the plant, which helps us get product to project sites quickly and drive results on behalf of our customers,” Brian Gurganus, vice president of asphalt at S.T. Wooten says.

“In fact, with the installation of our new drum alone, we can produce 33 percent more tons of asphalt per hour.”

SWITCHING TO A UNIFIED DRUM The increase in production can be attributed to the installation of a Dillman UniDrum as opposed to the previous double barrel drum system they were using.

PRODUCTION NOTES collection and recycling process more efficient,” Gurganus says. “The dust collector is now larger with more cubic feet of air. More air means it can catch larger materials before reaching the bag house."

The upgrades changed the existing Cyclone to an Inertial Separator built by Astec. S.T. Wooten says the main reason for the conversion was to decrease duct work, thereby reducing the maintenance costs of the existing dust control system.

“The new dust collector has allowed us to capture more dust particles and fines, recycling portions of the dust back into the asphalt mix, allowing us to increase efficiency, while also eliminating waste by recycling,” Gurganus says.

“We’ve installed a new insulated drum to replace the double-drummed system at the plant,” Gurganus says.

“The old drum used an elevator, which moved material between barrels during production. This would dry materials in the first drum before moving to the mixing drum.

“Our new drum is a “continuous mix” drum, which will handle the entire process by itself. This new drum will give us the same great results, while saving resources and making the process more efficient.”

With the installation of the new drum alone, S.T. Wooten can produce 33% more tons of asphalt per hour.

With an extra-long drum, the Dillman UniDrum mixer is uniquely capable of producing quality hot mix at a high production rate of 300 tph with a high percentage of recycled content if the company chooses. The extra-long drum length maximizes mixing and drying times to reduce fuel consumption and provide superior mixing.

While the Henderson plant mainly produces hot mix, warm mix and specialty mixes for airports and other facilities, they are capable of utilizing RAP as well as RAS in their mix designs.

KEEP THE DUST DOWN Asphalt plant mix facilities know that one way to be a good neighbor is to keep the dust down at their locations and that always means using a dust collection system. When S.T. Wooten made their plant upgrades, they decided it was time to update their dust collector system as well.

“One interesting aspect surrounding the recent plant upgrades has been the installation of a new inertial separator, which has helped make the dust

ADDITIONAL UPGRADES BOOST PRODUCTIVITY In addition to upgrading the drum and dust collector at the plant, S.T. Wooten also installed an additional silo.

“Like the other enhancements, this third silo was added to help us increase efficiency and productivity,” Gurganus says. “The additional silo has increased our storage by 50 percent at the plant, increasing the ability hold the asphalt until it’s ready to be moved to project sites. Adding the additional silo also means we will have a lot less waste on projects like I-85 where we have to change mixes a lot.”

The plant had two 200-ton silos and they added one additional 200-ton silo.

"This not only aids us with the additional storage capacity, but more importantly, helps us with the multiple mix changes that are necessary for this project on a daily basis," Gurganus says.

S.T. Wooten says these plant upgrades will help them support 650,000-ton paving projects like that of Interstate 85. The project was accelerated and over 300,000 tons were placed on the project last year.

To assist them in reaching their goal, we must help them with a number of choices they need to make in order get the best equipment to fit their

Helping with the equipment is a fairly easy and straight forward process. We use a series of questions to establish what the client needs as opposed to what they want. For instance, most clients want as big a plant as they can get, but are stunned to learn that the cost difference between a 250 ton per hour plant and

PRODUCTION NOTES Once we get these things sorted, the next thing that comes up is the question of ‘who would be a good plant operator?’

It always amuses me how much weight management assigns to computer skills. With today’s computerized control systems almost all operations are menu driven. If a person can operate a mouse, the computer operations are relatively simple. I assign a much higher value to mechanical skills. After all, if the plant is broken down, what good is the computer? In my experience people who tend to focus on computers and high-tech gadgetry seldom possess an equally keen interest in mechanical things.

The most valuable skill around the asphalt plant is the ability to keep it running. For this reason I recommend finding a reasonably intelligent person with a mechanical background. A person from the company's shop is a good choice. These people normally have an interest in mechanical things and are less likely to be intimidated by the noisy environment of an asphalt plant.

We often end up operating our client’s plant for a period of time while we train their personnel to staff their plant. If at all possible, we feel that the plant operator candidate should first be

32

assigned to the asphalt plant as groundman. Care should be taken at this time to fully explain each and every question the person asks. The answers these people receive at this point in their training bear heavily on their success later on.

We are convinced that the most important aspect of plant operations to teach a prospective operator is the repair and maintenance phase. Anyone can pick-up the fundamentals of the control room in relatively short order, it's simply a matter of pressing the right buttons in the correct sequence, given a certain set of circumstances.

What separates exceptional asphalt plant operators from the rest is the ability to address problems before they mushroom into a crisis that causes your company major downtime. To do this, the operator must be intimately familiar with the machine to be operated. Familiarity only comes from hands on experience.

This is why we want them on the ground around the plant for a period of time.

PROPER TRAINING IS KEY As with any training program, success is directly proportional to the amount of time the trainee spends in that environment. I've encountered situations where companies have streamlined this ‘outside’ phase of the operator's training. They think a few days is sufficient to teach some very complex operations. I disagree with this premise. Gaps in training could surface in costly manifestations of shattered parts which cost money to repair.

More importantly, a plant fails to make money while it's idle.

We closely watch the trainee, and once they begin to demonstrate an understanding of the hot mix processes and the function of the different plant components, we move them into the control room for short stints in the driver's seat. During this time, we think that it is essential to cement in the trainee's mind the fact that if things don't work outside, there's no need for anyone to occupy the operator's chair in the air-conditioned comfort of the control room.

We also find it advantageous to insulate the trainee from the worry of mix designs or specifications at this time.

Most companies have a member of

for what they are learning. It also allows them to see what their product is used for and the reasons why the pavers sometimes call for hotter/cooler temperatures or courser/finer mixes under certain conditions. The best plant operators have a certain amount of empathy for the crews who are using their mix. Remember, experience is an unparalleled instructor.

The Libra Self-Service Kiosks allow material suppliers to increase revenue by handling more truck traffic without increasing the number of operators. The kiosks increase customer satisfaction by reducing in-yard times, and by allowing the extension of site operating hours.

Benefits include: • Increases truck throughput without increasing costs • Allows operating hours to be extended for less cost • Frees scale house operators to handle other responsibilities • Significantly reduces data entry & ticket errors • Reduces in-yard times • Improves customer satisfaction • Quickly and automatically identifies trucks • Controls truck flow

The skill that will take the most effort to acquire is the ability to troubleshoot the plant. Most times, mechanical problems are self explanatory: It's not hard to see why the dryer won't turn when the drive belts are lying on the ground under the gearbox. Electronic troubleshooting is different story.

Repair companies specializing in electronics abound for good reason. In recent years, advances in computerized AC plant controls have simplified plant operations immeasurably. But in doing so, those systems have become so complicated that only the most experienced plant operators have the exposure needed to demonstrate any kind of diagnostic skills in contemporary electronics.

It must be remembered that an AC plant is a complex facility, which is probably why not everyone can operate one. To train a good plant operator requires consummate patience and a willingness to risk a certain amount of money. Very few plant operators can say that, early in their career, they didn't make mistakes which resulted in wasted time and product. This is to be expected. But the more thorough a person's primary training, the less likely it is that that person will experience a catastrophic problem of their own making.

AUSTIN MATERIALS Focuses on Paving Accuracy and Improved Safety on Airport Project Contractor saves $6,000 on Georgetown Municipal Airport resurfacing project with minimal staking or grade checking using a 3D paving system

A

ustin Materials provides high quality service for all asphalt paving, asphalt repair and concrete and aggregate services across Austin, San Antonio and surrounding areas in Central Texas. The company has several asphalt plants and aggregate plant locations, along with a fleet of paving sets, haul trucks and a material delivery department.

Austin Materials was selected for a runway resurfacing project for the Georgetown Municipal airport, which is located about 20 miles north of Austin. The regional airport has two active runways, including one that is 5,000 feet and another that is 3,800 feet.

Looking to save time and material on the job, Austin Materials made the decision to equip its asphalt paver with the Trimble PCS900 Paving Control System.

Working with SITECH Tejas, the local Trimble dealer, the team also adopted the Trimble SPS930 Universal Total Station, Trimble rovers and the Trimble GCS900 Grade Control System for site measurement, stakeout and earthwork.

The SPS930 was also selected to be used for survey, layout and topography survey tasks. The Trimble PCS900 system references the Trimble SPS930 Universal

Total Station and the Trimble MT900 Machine Target, using on-board software to compare the actual screed position and slope with the 3D digital design.

Phil Foley, vice president of operations for Austin Materials and Industrial Asphalt & Aggregates LLC., explains that the team selected the Trimble paving control system because it automatically guides the screed to lay exactly the right material thickness and slope by referencing the design files and surface levels.

Instead of manually having to spot check measurements, the machine measures the elevations and tolerances automatically, and it displays those values to the machine operator inside the cab.

TRAINING IS KEY Foley worked with Jason Royster, his local SITECH representative, to train

Austin Materials repaved the Georgetown Municipal airport runways laying down 8,200 tons of P401 of material in just seven paving shifts, meeting tolerances of +/- 1 millimeter

the operators how to use the 3D paving system. Royster and his team set up the Trimble SPS930 Universal Total Station and worked through the slope sensor setup and the initial calibration of the system. With the local SITECH team’s support, multiple Austin Materials employees were able to learn and operate the system from the onsite crew, job superintendent and the area general superintendent.

“As our industry has grown and the technology being used in the construction field continues to go up, it’s more important than ever to train

our operators and keep them up-to-date on new technology and best paving practices,” Foley says. “I can remember when I first started paving, we were using drag skis and string line, and today we have touchless skis. At Austin Materials, we get this and know the key to success and growth is safety, delivering a high-quality service and training our staff to be up on the latest equipment that makes them even better.”

PUTTING TECHNOLOGY TO WORK To start, Austin Materials received the airport runway design from the project owner, which included specifications for resurfacing and replacing runway lights, electrical and some utilities. Austin Materials referenced the project site measurements using a Trimble total station. Referencing

ACON0618_46-49_JobsiteAustin_J.indd 47

the 3D plan in Business Center, the team could compare and verify the elevations listed in the plan with the existing subgrade. Foley points out this was significant because if any variations are not identified early, before work begins, Austin Materials is ultimately responsible for any additional costs; missing completion deadlines or mistakes could result in non-payment or full removal and replacement of the surface.

“With Business Center—HCE, we can more accurately estimate materials and minimize the use of more expensive material,” Foley says. “This is important because if we’re off on those measurements, it can make the difference between whether the project is profitable and whether we lose money on it. The Trimble total station also allows us to control the jobsite better, which improves safety because there are fewer moving

Following the initial meeting, the team developed a strategic paving plan, working with the general contractor and business owner. The goal was to maximize safety on the jobsite and minimize any impacts to the existing runway and business. Then, Austin Materials laid down and compacted each layer of asphalt to the appropriate depth and density levels. Foley explains that skilled operators and the quality assurance team

Phil Foley, vice president of operations for Austin Materials and Industrial Asphalt & Aggregates LLC., explains that the team selected a 3D paving control system because it automatically guides the screed to lay exactly the right material thickness and slope by referencing the design files and surface levels.

Project Overview

collaborated closely to minimize transitions along the runway and to ensure the optimal smoothness and durability of the completed surface.

Using the Trimble 3D paving system, the operators can continuously pave, without the need to stake, check elevations or navigate around those stakes. The system uses active tracking technology to guarantee the total station locks on the on-machine target for millimeter-level control. Operators follow the 3D design precisely, meeting tolerances of +/- 1 millimeter at each phase. In total, the team laid down 8,200 tons of P401 of material in just seven paving shifts.

“Setting up grade stakes on a project like this can be time consuming because you have to wait for surveyors along the way and surveying in between lifts or after completion,” Foley says. “The pavers and trucks bringing the material in also have to navigate around those stakes, and the fact that you’re working on an active runway is another obstacle because equipment is in a very confined space.

“Having automatic grade control on our pavers just eliminates the near misses

48

and potential safety hazards, along with extra work that takes time. Now, our guys can just zero in and focus on getting to grade and tolerances quickly and producing the smoothest surface possible.”

With Trimble 3D paving equipment, Foley believes Austin Materials can now be more accurate when estimating materials usage and more productive when it comes to completing complex paving projects.

“As we bid projects, the Trimble total station will allow us to get creative with such a great system and put it on our full-size mills, which we’ll be able to run in tandem with our pavers,” Foley says. “This way we can deliver on our promises and produce an extremely highquality product for our customers, in the safest and most productive way possible.”

Recycling Efforts Save Virginia DOT Over on I-64 Rebuild

$15m

Through FDR & CCPR, VDOT is using over 1 million tons of recycled material

T

he Virginia Department of Transportation (VDOT) is in the process of widening 21 miles of I-64 in the Hampton Roads region. The work was broken into three segments, with construction starting in 2015 and

54

scheduled to finish in 2021.

The Interstate 64 Widening Project in York and James City counties and Newport News will improve safety, increase capacity and reduce congestion along this regionally significant interstate on the Virginia Peninsula.

“The existing four lane interstate was experiencing significant congestion and future projections for traffic volumes indicated an increased demand in the future,” Brittany McBride Nichols,

communications specialist for VDOT says. “The significant traffic volumes utilizing this corridor, coupled with the age of the roadway structure, made improvements to the roadway necessary and appropriate.”

The improvements will provide more lanes for evacuation and improve the vehicular level of service. It will also bring portions of the interstate up to current design standards to help improve the existing roadway conditions.

ASPHALT CONTRACTOR JUNE/JULY 2018 www.ForConstructionPros.com/Asphalt

ACON0618_54-58_Preservation_J.indd 54

6/11/18 2:29 PM

These updates also provided VDOT the opportunity to implement the use of recycled materials and sustainable construction processes on the project with the hopes of achieving cost savings. And so far, they have accomplished that goal to the tune of $15 million in savings, with more adding up every day.

RECYCLING ON I-64 VDOT is currently working on Segments II and III of the rebuild and is

www.ForConstructionPros.com/Asphalt

ACON0618_54-58_Preservation_J.indd 55

using sustainable methods like full depth reclamation (FDR) and cold central plant recycling (CCPR) to complete the reconstruction of the existing pavement as well as the roadway widening work.

“This is the largest pavement recycling project happening in the country right now,” Brian Diefenderfer, Ph.D., P.E. with the Virginia Transportation Research Council says. “There are two recycling processes being used on Segment II and Segment III; FDR and

Cold central plant recycling is similar to cold in-place recycling in that recycled material is used to create a revitalized asphalt material from what already exists. With CCPR however, contractors do not have to recycle the material in place but can use existing stockpiles of recycled asphalt pavement material from previous jobs.

PRESERVATION UPDATE

This project is unique in both its size and the fact that FDR and CCPR are not often used on the interstate system, whether combined or separately. Diefenderfer says this project is likely one of the highest traffic locations where these processes have been used on the interstate system to date and the only project where they are being combined in this way.

CCPR. FDR is being used to provide a foundation for the pavement system and the CCPR material is being placed as a base layer.”

The total design of the section is 12-in. of FDR, a 2-in. asphalt open graded drainage layer, 6-in. of CCPR and a 4-in. surface course of stone matrix asphalt (SMA).

This project is unique in both its size and the fact that FDR and CCPR are not often used on the interstate system, whether combined or separately. Diefenderfer says this project is likely one of the highest traffic locations where these processes have been used on the interstate system to date and one of only a few projects where they are being combined in this way. Another was a project on I-81 south of Staunton, VA that included FDR and CCPR in the right lane and was completed in 2011.

FDR FOUNDATION Another unique element is the way VDOT is using FDR on the new lanes.

“To the inside of the existing lanes, we’re adding a full width travel lane and a full width shoulder, so 24 feet to the inside in each direction," Diefenderfer says. "The use of FDR is unique here because we’re not recycling existing

56

material, but materials from other projects.”

The contractor on the project, Allan Myers, had the option to use recycled concrete aggregate or recycled asphalt pavement (RAP) and they chose the concrete in this case.

"Recycled concrete was more readily available in the market close to the project," Shannon Moody, public relations manager at Allan Myers says. "The CCPR for the project also requires a significant amount of RAP that we were not interested in taking from our RAP supply for the FDR." Instead, they took demolition material from old concrete projects, crushed it, screened it, graded it and brought it to the jobsite to be placed using the FDR process, creating the foundation for the pavement. This FDR process is helping to build the new 12 foot lane and a new 12 foot shoulder to the inside in both

directions for 7.08 miles on Segment II. On the existing lanes, the concrete pavement is also being removed and that foundation will be rehabilitated with the FDR process as well.

FDR will be done on 345,000 sq.yds. of existing lanes on Segment II and on 229,000 sq.yds. on Segment III. For the new lanes, 146,000 tons of recycled material is being used on Segment II and 201,000 tons of recycled material will be used on Segment III.

A CCPR mix cannot go down at the same speed as a traditional mix. Paving speeds need to be reduced to an average of 13-ft. per minute in order to maintain mix integrity.

ASPHALT CONTRACTOR JUNE/JULY 2018 www.ForConstructionPros.com/Asphalt

ACON0618_54-58_Preservation_J.indd 56

6/11/18 2:29 PM

WHY CCPR? After FDR is completed to stabilize the base of the pavement on Segment II, Allan Myers will add a 6-in. layer of CCPR material.

Cold central plant recycling is similar to cold in-place recycling in that recycled material is used to create a revitalized asphalt material from what already exists.

With CCPR however, contractors do not have to recycle the material in-place, but can use existing stockpiles of reclaimed asphalt pavement (RAP, or millings) from previous jobs. For this project, the CCPR is produced using 85% RAP and 15% #10 screenings; the screenings are a co-generated product resulting from the production of clean stone materials.

“The Virginia Asphalt Pavement Association estimates that we have over 10 million tons of RAP stockpiled with contractors in the state,” Diefenderfer says. “That’s a resource we can use with this process without requiring extensive amounts of virgin materials.”

Allan Myers purchased their Wirtgen KMA 200 Cold Recycling plant in 2017 to fill a need in the market.

"Allan Myers is always looking for innovative ways to do business," Moody says. "The CCPR innovative process and technology was an expertise we were interested in developing for the I-64 Segment II project and future work. In addition, recycled material is

Divided into three segments, improvements include widening I-64 from a four-lane section to six-lanes for approximately 21 miles, starting west of Jefferson Avenue (Exit 255) in Newport News to just west of Lightfoor Road (Exit 234) in York County.

The first operationally-independent segment in Newport News spans approximately 5.6 miles, from west of Route 143, Jefferson Avenue (Exit 255), to just east of Route 238, Yorktown Road (Exit 247).

Design-build contractor Shirley Contracting Co. LLC, supported by their design consultant Dewberry, broke ground on the project in September 2015 and delivered the $122 million project both on time and on budget on December 1, 2017.

Segment I improvements also included the: • Repair and widening of four bridges at the Fort Eustis Boulevard and the Lee Hall Reservoir interchanges • Replacement of two existing bridges at Industrial Park Drive • Extension of the on- and off-ramps at Fort Eustis Boulevard • Construction of noise walls • Landscaping along the median and corridor.

• Installation of drainage improvements, stormwater management facilities, and sign structure replacements.

The second operationally-independent segment is located in Newport News, James City and York counties, widening Interstate 64 approximately 7.08 miles, from 1.05 miles west of Route 199 (Humelsine Parkway / Marquis Center Parkway) near exit 242 to where the Segment I project ends, 0.54 miles east of Route 238 (Yorktown Road) near exit 247.

Design-build contractor Allan Myers, VA Inc., supported by their design consultant Rinker Design Associates (RDA), was awarded the $138.8 million contract for Segment II and broke ground in October 2016. Segment II is estimated to be completed in spring 2019.

Segment II improvements also include: • Repair and widening of nine existing bridges • Repair/extension of six major culverts • Raised median with landscaping • Drainage improvements, stormwater management facilities, noise barrier walls, sign structure replacements.

The third operationally-independent segment is in York County, spanning 8.2 miles from approximately 1.0 mile west of Route 199, Lightfoot Road (Exit 234), to 1.05 miles west of Route 199, Humelsine Parkway / Marquis Center Parkway (Exit 242).

On December 6, 2017, a $178.3 million design-build contract was awarded by the Commonwealth Transportation Board (CTB) to Shirley Contracting Company to complete Segment III of the I-64 Capacity Improvements Project.

A notice to proceed was issued to Shirley Contracting on January 3, 2018.

This segment is estimated to be completed in fall 2021.

Segment III improvements will include: • Repair and widening of four bridges at Colonial Parkway and Lakeshead Drive • Full replacement of the two Queen’s Creek bridges • Repair/extension of three major culverts • Extending on- and off-ramps • Reconstruction of the I-64 east off-ramp to Route 143 and the addition of a signalized stop at the end of the ramp.

• Drainage improvements, stormwater management facilities, noise walls, sign structure replacements

PRESERVATION UPDATE

advantageous for the environment and economical."

Wirtgen experts met with operators, quality assurance technicians and superintendents at Allan Myers to train them on the KMA 200 over multiple days. Wirtgen will also send personnel as needed to refresh training and monitor the performance of the equipment to ensure its operating correctly.

"The CCPR plant is set up 14 miles from the I-64 Segment II project at our existing asphalt plant which houses the raw materials," Moody says. "The material is loaded into and transported to the job in dump trucks, same as asphalt."

On Segment II, the bid quantity for CCPR is 168,000 tons and Segment III its 196,000 tons with all the RAP materials coming out of existing stock piles.

LEARNING CURVES As with any new piece of equipment and a relatively new process, there are bound to be challenges that you may not see on your typical paving job.

A CCPR mix can only be produced in temperatures greater than 50º F. If too cold, the foam can cool too quickly causing “stringers.” If this happens, compaction cannot be reached and the quality of

58

the roadway is threatened. This means the amount of time when the material can be placed is limited versus ordinary base mix.

"CCPR material also cannot be placed at the same speed as traditional mixes," Moody adds. "The speed of the paver is greatly reduced to an average of 13-ft. per minute which differs from hot mix.

"The moisture reduction requirements on CCPR are not required with hot mix," she continues. "The reduction needs to be met in order to place the fog seal and subsequent lifts of asphalt."

Allan Myers was able to use all the same equipment they would normally use on a hot mix paving job: • CAT AP655F model paver with SE50V Vibratory Screed set at 2600 • CAT AP1055 model paver with SE60V XW Vibratory Screed set at 2500 • 1 CB54B model CAT Asphalt roller and 1 CB64B Asphalt Roller with the drums on each set at high.

For the SMA layer, a hopper was installed into the paver and Allan Myers also used a Weiler E2850 Remixing Transfer Vehicle.

COST DRIVES CHANGE New processes also tend to encounter hurdles to acceptance and widespread implementation.

“The biggest hurdle for us with this project has been change,” Diefenderfer says. “But we have a great agency and industry team working together

VDOT has been monitoring performance of their recycled materials every year. The continued performance gives them confidence to complete projects like this that save both resources and money.

to do something different than what we normally do. We’ve had recycled materials perform well and are monitoring them every year and that performance gives us confidence.”

The language that everyone speaks however is money and money definitely talks on this project.

“Based on my calculations on Segment II and Segment III we’re going to see about $15 million in cost savings by using recycled materials,” Diefenderfer says.

To calculate these savings, he used as awarded material prices for the recycling design compared to a conventional design and it’s clear which design is more budget friendly.

“Individually, pieces of these two projects could be some of the largest recycling projects in the country and combining them has been a whole different animal for us," Diefenderfer says. "We’re pushing the envelope with pavement recycling and we’re trying to always do the best job we can.”

Just as your vehicles need proper alignment, so does your dryer.

Nearly all external dryer problems are caused by trunnion and frame misalignment. Long-term mis-alignment causes damage resulting in downtime and costly repairs. Even units that seemingly float properly can in reality be drastically out of alignment.

SIGNS OF MIS-ALIGNMENT

✔ Metal flakes from tires or trunnions ✔ Trunnion mis-location and trunnion bearing failure ✔ Poor wear/contact on tires and trunnions ✔ High drive motor amperage ✔ Excessive vibration ✔ Thrust roller and bearing damage ✔ Tire pad and keeper wear ✔ Lack of proper floatation Evans & Daniels uses precision laser and sighting techniques to restore your unit to proper alignment settings.

RESURFACING

Evans & Daniels uses highly specialized grinding equipment that can fit into the tightest of spaces. We resurface tires, trunnions, thrust rollers and tire thrust faces.

THE LAST EXIT

The Power of Plastic Dow Chemical Co., is partnering with Indonesian associations and the Indonesian government to engineer a means to incorporate plastic waste that washes up on Indonesian beaches into asphalt pavement mixtures

Plastic waste can be mixed with asphalt to create roadways that are both hihgly durable and sustainable.

T

o help address the global issue of plastic-contaminated oceans, Dow Packaging and Specialty Plastics (P&SP), a business unit of The Dow Chemical Co., is partnering with Indonesian associations and the Indonesian government to engineer a means to incorporate plastic waste that washes up on Indonesian beaches into asphalt pavement mixtures.

Aimed at helping the Indonesian government reach its goal of reducing plastics waste in the ocean by 70 percent by 2025, ADUPI will continue to provide the necessary plastics waste material, and together with Dow’s technology expertise, will work with various stakeholders to turn that waste into sustainable roads.

POTENT PLASTIC At the recent United Nations Environment Summit, plastics waste contamination is now recognized as a

66

planetary issue with much of the world’s marine ecology under threat.

According to research, plastics waste in Indonesia is estimated to reach 9.52 million tons by 2019, or 14 percent of the country’s total waste.

“Companies do not make plastics with the intent of it ending up in the ocean, and we acknowledge the strong role the industry must play in order to help eliminate ocean plastic waste by 2035," Bambang Candra, Asia Pacific Commercial vice president at Dow Packaging and Specialty Plastics says. “We are extremely pleased with the success of this project and what it promises. The technology behind these new plastic roads has proven simple enough for wide

scale application in Indonesia’s transport infrastructure. We are confident it will help manage the sheer volume of plastics waste the country produces.”

The first plastic road trial was completed in Depok city, West Java, Indonesia, in Q3 of 2017. It saw 3.5 metric tons of plastics waste material mixed into asphalt to create a 1.8 kilometer long proof of concept, which covered a total area of 9,781 square meters. The result of the two-month long project was a highly resistant plastics waste road that was highly durable . While still undergoing further testing at the PUSJATAN (National Centre of Road and Bridge Construction), the project has been identified by Indonesia’s Coordinating Ministry for Maritime Affairs as one of national importance.

The success of this project furthers Dow’s 2025 Sustainability Goals to advance a circular economy by delivering solutions to tackle environmental issues, raise awareness on recycling and reuse of plastics and create a sustainable business environment for plastics producers and consumers alike.

According to research, plastics waste in Indonesia is estimated to reach 9.52 million tons by 2019. This amount of waste could be used to pave an equivalent of over 118,000 miles of new roads.
