Toiling as a young reporter covering the municipal council beat, it became quickly apparent that road construction was a particularly thorny matter for local politicians, small business owners and taxpayers Even something as simple as a repaving project on a local residential street could cause headaches for all of the above. So while much ink was spilled over roadwork around major business corridors or along high-traffic arterial roads, even modest upgrades that caused delays on the quietest streets often led to many angry phone calls to local politicians. Managing the public and their expectations around projects was almost just as important as the actual contstruction work. It was also the one area where I routinely saw contractors and government officials fall short. The result was often an angry public and less buy-in next time a project came forward. I'm as guilty as anyone to point to NIMBYism as the cause of opposition to road construction, housing developments, quarry expansions and even data centres. Yet even though every project will have its core group of detractors, an effective communication plan can help mitigate those complaints and keep most people onside. Unfortunately, too little attention is often paid to managing the public. Over the years, I've seen it left to politicians to take the lead. And, unfortunatley, if something ultimately goes wrong, those same politicians will quickly deflect the blame to bureaucrats or the contractor. I witnessed a particularly egregious form of this years ago during a renovation project of an important municipal facility. The renovations came in not only over budget but blew past the original timeline. A few councillors blamed the misman-

agement of the project on both the city administrator as well as the general contractor. Of course, the truth was more nuanced. The local politicians had involved themselves in the project from the beginning, often making decisions on the design as well as the supplies without informing either the general contractor or city administrator. This was what caused cost overruns and delayed the project's completion. Making matters worse, those same politicians also offered the public overly optimistic timelines on when construction would finish even though they knew those timelines were wrong. Then, once it became clear the project was both overbudget and late, they found their scapegoats. Witnessing this taught me the value in effective community consultation. While something as extreme as what I described above is a rare occurence, the importance of ongoing communication with the public is more vital than ever. With social media never stronger and mainstream news sources never weaker, it's now too easy for one or two extreme voices to shape the conversation. An irate (and inaccurate) Facebook post about a construction project could be read by half the community in one night. While a detailed, consistent communication strategy may not stop that, it can dull its effect. Mike Lacey is editor of Rock To Road magazine. He can be reached at mlacey@ annexbusinessmedia.com

industry news Nelson quarry expansion faces potential legal hurdle from city of Burlington The recently approved expansion of the Nelson Aggregates quarry is now facing a potential legal challenge, as the city of Burlington said it will file a request for review of the Ontario Land Tribunal (OLT) decision. In a Sept. 15 press release, the city also said its request will include an application for judicial review with the Divisional Court before the Sept. 17, 2026 deadline. The city says its legal counsel identified
issues with the decision that warrant further consideration, and that it is pursuing both processes to preserve the legal options available within the required timelines. The OLT granted approval to Nelson Aggregates for expansion of its Burlington Quarry on Aug. 18, 2026. The expansion consists of two segments: an 18-hectare parcel extending to the south of the existing quarry and a 60-hectare extension to the west.
OSSGA joins Ontario Corps The Ontario government has announced the addition of the Ontario Stone, Sand and Gravel Association (OSSGA) to Ontario Corps to leverage its members and construction equipment during an emergency. During emergencies, OSSGA can call on its members to facilitate access to expertise and available construction equipment such as excavators, bulldozers, trucks, snow removal machinery, portable generators and pumps. The province says the equipment could help with flood mitigation, debris clean up, restoration efforts, transporting supplies and other activities as needed. The Ontario Corps network can be mobilized within 24 to 72 hours to help communities hit by emergencies, deploying resources such as personnel, debris removal tools, supplies, flood barriers and drones. The province says it encourages people of all skill levels and professional backgrounds to volunteer for Ontario Corps. Volunteers are provided with training and matched with partner organizations based on their skill levels, interests and availability. Ontario Corps has been deployed on several occasions to support emergency response. Most recently, Ontario Corps volunteers were deployed during the response to summer flooding in Niagara Region and during the 2026 wildland fire season. OSSGA joins Chartered Professional Accountants of Ontario, The Home Depot Canada, Labatt Breweries of Canada, Niagara College, Ontario Chamber of Commerce, Ontario Mine Rescue, Ontario Road Builders’ Association and Uber Canada as Ontario Corps’ latest partners.
Nelson Aggregates first applied for a license to expand its quarry operation in 2004. The expansion was ultimately denied by the Ontario Municipal Board in 2012. Nelson began its studies for a second application in April 2013 and submitted its Aggregate Resources Act (ARA) application in May 2020.
OSSGA honours Royal Botanical Gardens The Ontario Stone, Sand & Gravel Association (OSSGA) hosted a special ceremony at the Royal Botanical Gardens (RBG) to rededicate the OSSGA Bronze Plaque Award at the Rock Garden. OSSGA says the ceremony highlighted the importance of land stewardship through the recognition of one of Ontario’s most notable examples of aggregate site rehabilitation. OSSGA says its Bronze Plaque Award has been its most sought-after environmental award since 1975. It recognizes former aggregate sites that have been transformed into outstanding examples of land and community use. The Rock Garden, formerly a gravel pit, originally received the Bronze Plaque Award in 1976. A new plaque will be relocated within the Rock Garden to reflect changes and renovations made to the site over the years.

FIGHTING FATIGUE

Workplace fatigue is considered a form of impairment that can compromise safety. Credit: © dinatychynska/ Adobe Stock
Safety is vital on any jobsite, yet worker fatigue poses real risks and is too often overlooked 10 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026
> Safety is often only associated with what can be seen on a jobsite: high-visibility vests, lighting for nighttime construction and even workers wearing proper protective gear and following safety procedures. All of these can easily be spotted and assessed, but what about something affecting worker safety that isn’t so readily visible to the naked eye? Fatigue can be easy to miss, but it plays a huge role in keeping any jobsite safe. A worker who is tired is prone to making mistakes and paying less attention to their surroundings. This puts everyone on the site at risk. However, there are ways to both evaluate worker fatigue and mitigate its risks.
DEFINING WORKPLACE FATIGUE An October 2019 report from CSA Group divides fatigue into three different states: • The mental state is defined as a reduced mental capacity, inattentiveness and indecisiveness. • The physical state is defined as physiological weakness or degradation and feeling physically exhausted or weak. • The subjective state is defined as feeling tired, drowsy, weary, sleepy or lethargic. The report says these states of fatigue can have effects on both mental and physical performance, including: • Impaired mental capacity • Lack of alertness • Diminished cognitive processing • Loss of situational awareness • Impaired driving performance • Impaired cognitive performance • Impaired physical capacity • Performance impairment • Reduced work capabilities • Impaired job/task performance The Canadian Centre for Occupational Health and Safety (CCOHS) says fatigue can be influenced by workplace factors such as shift rotation patterns, balanced workloads, timing of tasks and activities, availability of resources and the workplace environment. “Fatigue is more than just being tired,” says Mathew MacLeod, Senior Technical Specialist, Occupational Health and Safety, CCOHS. “It’s a form of impairment and is a recognized workplace

hazard.” In roadbuilding and aggregates, staying alert and aware of your surroundings is crucial. A slight delay in cognitive processing, especially when operating heavy machinery, could cause serious harm. This is why prevention is key.
MANAGING WORKPLACE FATIGUE “The most effective strategies to prevent fatigue are those that are developed in collaboration with workers and health and safety committees and representatives,” says MacLeod. “Specific policies and procedures may differ depending on the workplace and type of work performed.” Whether it’s a night crew paving a section of road or heavy equipment operators putting in long hours in a quarry, MacLeod says there should be a process for assessing risk and establishing ways to identify and address tasks and factors that may cause fatigue. In addition, employers should also identify situations where fatigue could increase the risk of an incident. “Some examples of this could include talking with workers, conducting risk assessments and inspections, and looking at previous incidents and injury trends and root causes,” he says. So how should a worker approach a situation where they think someone might be Gradually scheduling workers from day to night shifts and allowing enough rest in between can be effective fatigue mitigation strategies.

too fatigued? “They should have procedures and reporting mechanisms in place, but in general, they should notify their supervisor or manager about their concerns,” MacLeod says. “In addition, they could also speak to the health and safety committee or representative, if they have one. Depending on the situation, they could also speak with the co-worker privately to discuss their concerns.” One of the first steps toward managing fatigue is having predictable shift schedules to allow for enough rest in between. This is particularly important for workers on night shifts. For companies where there is not a dedicated night crew, shifts should be rotated from morning to afternoon to night so workers’ minds and bodies can adjust to their new hours. Beyond this, MacLeod says the strategy needs to be customized to meet the needs of the workers and workplace. “This involves following the process of identifying, assessing and controlling fatigue-related hazards and factors,” he says. 12 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026

Something that should also be considered in relation to night work is how workers can get home safely after their shifts. The CCOHS says 17 hours awake is equivalent to a blood alcohol content of 0.05, and 21 hours awake is equivalent to a blood alcohol content of 0.08, the legal limit in Canada. While it’s understood workers should be getting enough sleep before they clock in, this isn’t always the case, especially when
sleep conditions are not optimal like during hot summer days. MacLeod says standard workplace procedures should include processes for getting fatigued workers home safely. “In non-emergency situations, this may include the supervisor calling a cab or making other travel arrangements to ensure the worker gets home safely,” he says. Most importantly, supervisors need to regularly check in with their teams, and everyone should learn how to recognize the signs of fatigue, whether it’s for themselves or someone else. Supervisors can opt for a more formal assessment if they feel a worker is too fatigued to perform their job duties safely. “Formal assessments will look different for each workplace and the type of jobs or tasks the worker is performing,” MacLeod says. “But in any case, workers should be consulted throughout the assessment process to ensure the right solutions are put in place.” Other actions employers can take to help reduce fatigue in the workplace include: • Eliminating or reducing extended periods of mentally or physically demanding work. • Establishing predictable shift schedules that rotate forward and allow enough rest. • Ensuring workers are taking breaks. • Varying tasks to help break up repetitive work. • Using bright lights. • Protecting workers from heat stress and high noise exposure. • Implementing training to help identify and handle fatigue-related impairment on the job.
time where they are not getting enough sleep each day. Luckily, there are strategies for improving sleep, and many of them fall under the category of common sense. MacLeod says for good sleep, workers should establish a bedtime routine, avoid screens before bed and put phones on “do not disturb” mode. “Making sure the room is cool, dark and quiet can also help,” he says. “Workers should also see their doctor or a health professional if they’ve been having trouble sleeping or think they may have a medical condition impacting their sleep.” Proper hydration and nutrition are also key to a good sleep. MacLeod says workers may want to try having their main meal before their shift if they are working nights. MacLeod adds employers can take opportunities to educate workers on healthy eating habits to help ensure they’re eating a balanced diet, at regular times and not skipping meals. Incorporating exercise and avoiding caffeine, nicotine and alcohol can also help to improve sleep.
A GROUP EFFORT Managing fatigue comes down to both employers and individual workers being responsible for their well-being. At the management level, fatigue needs to be addressed and assessed. Employers must keep their employees informed of the dangers of fatigue, offer avenues for reporting fatigue and ensure they take measures to reduce the amount of fatigue a worker takes on in a given shift by utilizing safe strategies. “Employers should take a collaborative approach with workers to identify and address workplace factors causing fatigue and situations where fatigue could increase the risk of an incident,” MacLeod says. Individually, workers should practice healthy habits to reduce workplace fatigue. Employees must also recognize signs of fatigue in themselves and others and know how to report fatigue to management. It’s only human to feel tired at work, but maintaining a safe and healthy workplace is knowing the line between everyday weariness and actual fatigue.
THE POWER OF A GOOD SLEEP Sleep might just be the most important factor in combating workplace fatigue. A worker who feels fully rested and ready to work is less likely to feel overly fatigued by their job duties. However, getting the best sleep possible can sometimes be difficult, especially for night shift workers who must sleep during the day. According to a national Leger survey commissioned by Eisai Limited, 41 per cent of Canadians are getting fewer than the recommended seven hours of sleep per night. This can lead to an accumulation of sleep debt, which can make someone feel more tired over a period of SEPTEMBER/OCTOBER 2026 | ROCKTOROAD | 13 RTR_CalroseElectric_MarApr23_MLD.indd 1

The City of Regina navigated supply chain spikes, century-old subterranean surprises and tight urban footprints to rebuild a vital downtown corridor > Construction in any urban environment provides challenges. But those are amplified when transforming the heart of a city’s downtown, which includes tearing up roads and sidewalks that are more than a century old and no one has an idea what lies underneath. Yet as construction nears completion, those at the City of Regina can now look back at what they learned during the 11th Avenue Revitalization Project and begin to apply those lessons to future projects. Running between Albert and Broad streets, 11th Avenue is a key cultural, economic and transportation corridor for the city.

So, it’s no surprise that this four-year project is the centrepiece of a broader revitalization plan for Regina’s downtown. “The 11th Avenue revitalization project is part of a city centre revitalization plan to create a walkable, welcoming and safe downtown that attracts more people and businesses to live, work, visit and invest,” explains Chris Warren, director of roadways and transportation with the City of Regina. Yet transforming the street, sidewalks and underground infrastructure of an older, congested urban centre, and doing so in phases of two to four blocks at a time, came with a slew of hurdles. The project has required a revamped budget and construction schedule, a detailed plan for emergency services, and extensive communication and co-ordination with store owners, transit, utility companies and others. Work began in 2023 with deep underground utility replacement. Years three and four were when new water mains, roads and sidewalks were installed. This October, the project is expected to be complete.
EARLY CHALLENGES This was not just about modernizing the streetscape. There were upgrades to the underground infrastructure, such as water, sewers, utilities and telecommunications. “This is right dead in the city centre; very congested, very narrow roads with

the building of the foundations right up adjacent to the city right of way,” Warren explains of the challenges. That first challenge was in the planning stages. The City wanted to co-ordinate the work so that once the road was opened, all the infrastructure could be replaced at once. “A lot of planning and co-ordination went into trying to define the schedule,” Warren explains. “But we just really found that there was just too much work and too much congestion to safely and efficiently do all the work all at once.” Instead, they adjusted to a phased approach to the schedule. Power and telecommunication companies would come in first and, once completed, the road crews would take over. Another early challenge was cost. Warren explains the plan was formulated in 2022 and 2023, a time when the world was coming out of the COVID lockdowns and inflation skyrocketed. That required them to go back to city council and adjust the project. The unpredictability of what lay underneath a road as old as 11th Avenue offered a SEPTEMBER/OCTOBER 2026 | ROCKTOROAD | 15
unique challenge, says Ryan Froehlich, co-ordinator of major projects at the City of Regina. “There’s not a lot of records for all the buildings that are downtown. So, when removing sidewalks, we were unsure of what we would uncover underneath the sidewalks,” he says. What crews did uncover were old railway beds and railway ties, building foundations and old beams. “Just a lot of concrete infrastructure we had to work around and manage as we went,” he says. The key, he adds, was understanding they would have to adjust on the go without losing sight of the overall design. Another challenge of working in a narrow, congested urban environment is locating a suitable laydown area. While most of the equipment could be parked on side streets, they needed a location for fill, catch basins, manhole covers and other materials. Luckily, Taylor Field, the former home of the CFL’s Saskatchewan Roughriders, was only a few blocks away. “While we were doing all the underground work, the contractor was hauling all their fill material to the Taylor Field site and conditioning the material there,” Froehlich says. “And then when they're ready to backfill, they bring back that conditioned material.” Francisco Paredes, senior engineer with the City of Regina, notes that another consideration was emergency services. “Because we are using space in some of the side streets, we created emergency response plans that we shared with emergency services so they know, in case of an emergency, which street to take and where
11th Avenue is a key business and transit hub for Regina. PHOTO: City of Regina
to enter because everything is fenced,” he says, adding they also provide them with keys to open any location on the site if they need access.
MANAGING BUSINESS, TRANSIT AND TRAFFIC 11th Avenue is a key business and transit hub for Regina. So, it was imperative to mitigate the impacts on businesses, pedestrians and transit users. While businesses were impacted throughout the construction process, the real challenges didn’t come until 2025 when sidewalk work began. “Being able to maintain access to the businesses as well as being able to do the work and pour brand new sidewalks right in front of their single access is a huge challenge,” Warren says. They achieved this by using a multi-layered approach.
A rendering of 11th Avenue once the project was completed. PHOTO: City of Regina 16 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026
To help mitigate issues during construction, they completed some of this work on weekends and overnights. However, it was communication that defined their strategy. Paredes says in the beginning of the 2025 construction season, the City hand-delivered letters to every business along that stretch with details about that phase of the project. As well, they conducted interviews with any business that was interested. “Also, we set up a system where we work very close together with the Regina Downtown Business Improvement District,” he says. If construction veered off the original plan, emails would be sent out informing every business. As well, the city created and distributed wayfinding maps to help customers navigate their way through construction. “There's a City of Regina 11th Avenue project page. Residents are encouraged to go onto the project page and they can see an updated wayfinding map so they can kind of have an idea of how to get around before they get downtown and get lost,” Froehlich says. The city had to adjust the work schedule when sidewalk installation began. With underground and road work, they could leave a pocket so that customers could still access businesses, Froehlich says, but once sidewalk construction began, that access was gone. “It’s a lot more impactful,” Froehlich explains. “A lot of these businesses, they only have the one access off 11th Avenue.” The solution was to break the work down into small, door-to-door phases.
A rendering of what 11th Avenue would look like. PHOTO: City of Regina
“We worked with the businesses to make sure that we're replacing their sidewalk after hours or on weekends or days when they're not open, just to minimize that impact as much as possible,” he says. The city would provide bi-weekly updates on the progress of the project and as crews crept closer to a specific business, the communication ramped up even more. One advantage of those early spring interviews with businesses was that it helped tailor the schedule. As an example, Froehlich points to a restaurant that informed them in April it was shutting down in July for kitchen renovations. Froehlich says they planned their schedule to install the new sidewalks in front of the restaurant at the same time. Paredes notes there was a specific challenge for businesses last year near the end of construction season. The plan was to finish up the sidewalks once the road was completed, but that did result in major closures. “We created QR codes that the people were able to just scan on site in the fences and so they could move around,” he says.
LESSONS LEARNED Froehlich says the communication strategy they developed is something they will apply to other construction projects. “I know construction is always a pretty big impact on all the businesses. So, getting out there ahead of time, being honest with them, making it known that we want to work with them, that we want to minimize the impacts and we want to get in and out of there as quick as we can to make sure we don't affect their businesses,” he says. Another lesson learned, at least when it comes to tearing up old streets and sidewalks, is improved investigation before digging. “The investigation of the underground infrastructure is one of the main things that we have learned here,” Paredes says. “We have other projects already in the planning stage and we are already applying that experience.” The city is utilizing hydrovacing in new projects to find the precise location of underground utilities. From there, they create a 3D digital map they can use when drawing up final construction plans.

> Amrize and Kiewit had their work cut out for them: installing more than 154,000 tonnes of advanced, high-performance asphalt on the North Runway of Vancouver International Airport (YVR) without interrupting daily flight operations. The six-month operation required significant co-ordination and meant that work could only be done overnight between 10 p.m. and 6 a.m. from Sunday to Friday. The paving program was completed over 115 eight-hour shifts with approximately 115 lineal metres of mainline paving being completed every night with additional crews completing level course and taxiway paving concurrently. During the largest single shift, Amrize says approximately 2,300 tonnes of asphalt were placed to cover 230 lineal metres of the main runway. More than 100 crewmembers operated more than 100 pieces of equipment during the operation. This included two synchronized 10-metre screeds that were used to complete Canada's first 20 metre echelon asphalt milling paving across three kilometres of runway.
"Transforming YVR’s North Runway was a once-in-a-generation project," said Lincoln Kyne, Regional President, Aggregates and Construction Materials, Amrize Building Materials. "By combining high-performance asphalt with advanced paving technology, we’ve ensured the longevity, resilience and safety of this critical piece of airport infrastructure." The project also relied on a highly specialized fleet that included: • Large-scale milling machines • Material transfer vehicles to ensure continuous paving • Steel-wheel and pneumatic rollers for precision compaction • Thermal profiling and density measurement equipment • GPS-guided survey and quality-control systems • A dedicated logistics fleet to maintain uninterrupted material flow The demanding nature of one of Canada's busiest runways, especially one that had seen 30 years of use, meant that temperature uniformity and accuracy were paramount. The operation utilized both precision mmGPS paver control and thermal imaging to ensure these metrics were correct down to the millimetre. The mmGPS paver control used satellite-guided positioning to control screed elevation and slope in real time to ensure the asphalt surface met exact design tolerances across the full 20-metre paving width. The runway required profiling to re-establish proper grades as asphalt fills varied from 50mm to 120mm. The mmGPS system provided the level of control needed to maintain the correct elevation despite the variations in the mat thickness. Thermal imaging continuously monitored asphalt temperature behind the paver to confirm uniform compaction conditions. Amrize says that without these systems, inconsistencies in

A project of this scope and specificity required more than overnight hours, equipment and a dedicated workforce. It needed the right kind of asphalt. Amrize engineered a custom-designed, high-performance, EPD-certified mix developed specifically to meet strict gradation criteria established by YVR. The mix was engineered locally at Amrize's Mitchell Island plant to handle extreme loading from wide-body aircraft, frequent braking and acceleration and wide weather variability typical of coastal British Columbia. The specialized mix incorporated polymer-modified asphalt binder, Surface Tech aramid fibres and hydrated lime, resulting in a high-performance asphalt mixture well suited for the demanding heavy loading service conditions of large aircraft.

Smarter stockpiling By leveraging automation and onboard diagnostics, today’s conveyors maximize stockpile volume, lower fuel costs and eliminate unnecessary material handling Today’s conveyors are focused on increasing return on investment through operating efficiencies. Using automation, conveyors reduce material handling and increase stockpile capacity. By building more uniform piles, producers can spend less time reshaping piles, lowering fuel and labour costs and putting less wear-and-tear on machines. As well, some conveyors, such as Superior Industries’ TeleStacker Conveyor, help to further lower day-to-day operating expenses through maintenance reminders, onboard diagnostics and remote monitoring. We take a closer look at some of the newest conveyors on the market.
SUPERIOR INDUSTRIES TELESTACKER CONVEYOR Superior Industries' portable radial stacker is designed for precise material placement and fully automated pile building. The conveyor was originally engineered to solve stockpile segregation. Its telescoping discharge, variable height and automated radial travel work together to place material throughout the pile as it's built rather than simply dropping it from a fixed point. With PilePro Automation, operators can run repeatable stockpiling patterns that produce consistent pile geometry, maintain in-spec gradations and reduce the need for rehandling. The automation also backfills the rear of the stockpile, which Superior notes increases storage capacity by 30 per 20 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026

cent on the same footprint. The TeleStacker Conveyor comes in three models – FD Axle, XTP Swing Axle and Portable Axle. All three models are built for continuous production in demanding environments. Its patented FB Undercarriage, closely spaced structural members, cross-braced truss geometry and heavy-duty, loading sharing stinger support rollers work together to control deflection and maintain stability across long conveyor spans. Superior also designs and manufactures its own conveyor components, allowing idlers, pulleys, impact cradles, sealing systems, belt cleaners and other components to be selected or configured for abrasive material, high tonnage and severe operating conditions rather than relying on generic off-the-shelf parts. Where the models differ is in setup. Operations moving equipment regularly between jobsites would turn to the FD Axle, which Superior states can be converted between travel and production configurations in seconds. Producers that relocate, but not as frequently, prefer the patented XTP Swing Axle, which Superior states reduces setup time between stockpiles without the chain and sprocket complexity of traditional swing axles. For stationary or long-term processing sites where highway transport isn't required, pit portable models deliver
the same stockpiling performance. The biggest savings typically come from handling material fewer times. Because the TeleStacker Conveyor builds larger, more uniform stockpiles directly, Superior states producers spend less time reshaping piles with wheel loaders. This reduces fuel consumption, machine hours, tire wear and labour. Superior notes automation further lowers operating costs through maintenance reminders, onboard diagnostics, remote monitoring and consistent stockpile building that requires less operator intervention.
PROSTACK TW 36-150 RADIAL TELESCOPIC CONVEYOR The ProStack TW 36-150 is a high-capacity 150-foot radial telescopic conveyor engineered to maximize stockpile volume while minimizing material handling costs. Designed for demanding quarrying, mining, aggregates and bulk material applications, it delivers up to 270° radial movement, creating larger, more efficient stockpiles and reducing the need for wheel loader rehandling. The TW 36-150 features tool-free deployment, road-towable transportability, automated stockpile patterns and a user-friendly design that enables rapid setup and reduced downtime. With stockpile heights exceeding 48ft 10in (14.9m) and capacities of more than 102,000 cubic

Combining robust construction, reliable dual-drive performance, and advanced stockpiling technology, the ProStack TW 36-150 helps operators improve material quality by reducing segregation, degradation and contamination while delivering industry-leading stockpiling efficiency.
ASTEC INDUSTRIES 36125T MOBILE SUPERSTACKER Featured at CONEXPO-CON/AGG 2026, the 36125T Mobile SuperStacker is a tracked, radial, telescoping conveyor engineered for fast setup, high mobility and efficient stockpiling. According to Astec, the unit is self-contained with an on-board genset, tracked mobile and trailer transportable. It has a 125foot telescopic conveyor for huge stockpile capacity while maintaining high throughput rates at up to 880tph. The unit is also fitted with Astec’s Wizard Touch auto-stockpiling program for desegregated piles. “It's a unique machine on the market that ticks a lot of boxes for various customers,” states Astec’s Allan Gilmore. “It's the only unit that can track on and off a lowboy trailer and be transported around the country on a trailer.”
NORDTRACK CT85 Metso’s Nordtrack CT85 is a versatile, heavy-duty mobile stacking conveyor designed to help aggregate producers handle material efficiently across a wide range of applications. Whether working in quarrying, sand and gravel production, recycled aggregates or contract crushing, the CT85 provides a flexible solution for stockpiling and material transfer.

THE HYBRID ADVANTAGE

Hybrid equipment is helping contractors reduce fuel use, improve uptime and rethink roadbuilding projects
22 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026
> Roadbuilding contractors face a real dilemma: rely on diesel equipment that can meet the demands of the job but faces growing noise and emission restrictions, or choose fully electric machines that are cleaner and quieter but may fall short on runtime, charging access and performance under heavy loads. Hybrid equipment offers a practical middle ground. By combining diesel and electric power, hybrids give contractors the performance they expect, with lower fuel consumption, reduced emissions and less unnecessary engine load – all without requiring major changes to the way crews work. This combination is why more contractors are turning to hybrids to control costs and stay ahead of tightening regulations. Hybrids do introduce some new considerations for operator
training and maintenance, but they’re proving their value where it matters most: maximizing uptime, lowering costs and helping keep projects moving.
THE UPTIME ADVANTAGE OF HYBRID EQUIPMENT
> By combining diesel and electric power, hybrid equipment gives contractors the performance they expect with lower fuel consumption, reduced emissions and less unnecessary engine load.
Managing costs without sacrificing performance is one of the biggest challenges facing today’s roadbuilding industry. Every hour equipment sits idle – waiting to be refueled, recharged or repaired – is an hour lost to productivity and profitability. On projects with lane closures or restricted work windows, even a short delay can disrupt schedules and extend timelines. the need for external charging infraregulations restrict its use during certain Hybrid equipment offers the right adstructure. That’s a real advantage on city hours. Instead, hybrid equipment is used, vantage: greater uptime without sacrificing sites or roads where electrical service is operating in zero-emission electric mode the benefits of electric operation.

A single quieter site matters for more than comfort, an option as local noise and emissions tank of diesel can deliver a full week of runtime. Hybrid equipment offers contractors a practical middle ground between diesel and electric power. The diesel engine also recharges the PHOTO: Cooper Equipment Rentals battery on-site, reducing or eliminating

it also helps contractors comply with stringent noise and emissions requirements while extending working hours in locations where excessive noise would otherwise bring operations to a halt. As infrastructure investment increasingly focuses on dense urban environments, reducing both emissions and noise is becoming less of a competitive advantage and more of a prerequisite for winning work. Hybrid equipment provides contractors a practical way to meet these expectations while maintaining productivity, keeping projects on schedule and avoiding the compromises that come with fully electric or traditional diesel equipment.
FUEL SAVINGS THAT ADD UP Fuel is one of the largest controllable costs on a jobsite, making equipment choice an important part of the equation – particularly on road and infrastructure projects where equipment runs long hours across multiple phases. Fully electric equipment eliminates fuel entirely, but the total cost isn't always lower once factoring in 24 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026

charging infrastructure, available power, and rental rates. Hybrid equipment burns fuel only when it’s needed, cutting fuel consumption without changing how crews operate. Many hybrid models can lower fuel use by as much as 30 per cent compared to conventional diesel equipment. Those savings compound quickly. Even modest per-day savings add up over a multi-week or multi-month project: fewer deliveries, less time spent refuelling, lower total fuel spend. On a competitive bid, that difference can be the deciding factor between winning the job or not.
ONE MACHINE FOR EVERY PHASE Fuel savings aren’t the only place flexibility pays off. The same adaptability shows up in how contractors plan equipment across a shifting scope of work. A job that starts in one place can quickly move somewhere else and equipment that worked perfectly one day may not be the
right fit the next. Instead of renting one machine for open roadway work and another for tight, sensitive urban applications, a hybrid handles both. A hybrid boom lift, for example, can work a road corridor using hybrid power and then transition to a downtown block where low noise and zero emissions are often required. No equipment swap needed. That flexibility simplifies equipment planning and reduces costs. Fewer equipment changes mean fewer deliveries and pickups through congested streets or active work zones, lower transportation expenses and less time spent co-ordinating rentals. When equipment can perform across a range of applications, it gives teams one less thing to worry about.
WHAT TO CONSIDER WHEN CHOOSING HYBRID EQUIPMENT Selecting the right equipment starts with understanding the demands of the project.
Hybrid equipment is especially valuable on urban roadwork projects. PHOTO: Cooper Equipment Rentals
Cost is usually the first consideration. While hybrid machines may have a slightly higher rental rate than comparable diesel models, they can lower overall operating costs on roadbuilding projects through reduced fuel consumption and improved efficiency. On projects where equipment is working continuously – such as paving, grading or urban infrastructure work, those fuel savings can add up quickly. Project conditions also matter. Hybrid equipment is especially valuable on urban roadwork where crews contend with frequent stops and starts, traffic restrictions and emissions or noise requirements. By reducing engine load during low-demand operations while still providing full power when needed, hybrid machines maintain productivity without sacrificing performance. When it comes to maintenance, hybrids combine two power systems, which means more components to maintain and not every technician has the training to service them yet. Working with a rental partner that understands hybrid technology ensures operators receive the support they need. Most operators can adapt to new equipment quickly, but understanding how hybrid systems manage power can help crews get the most from equipment. The best equipment decisions depend on the jobsite. When matched to the right application, hybrids can help reduce fuel costs, lower emissions and improve overall jobsite efficiency.
MAKING SMARTER EQUIPMENT DECISIONS The demands of roadbuilding have changed and so has the way contractors evaluate equipment. Fuel efficiency, emissions compliance, maintenance requirements, operating costs and the flexibility to adapt to changing project conditions now matter as much as performance. For contractors considering hybrid equipment, the transition doesn’t have to be all or nothing. Rather than replacing every diesel machine, start with the jobs where hybrids deliver the clearest return: urban areas with noise restrictions, projects with unpredictable runtimes or bids where fuel costs could change the outcome.

DUST ON THE MOVE
In Canada, workplace silica exposure is linked to around 570 lung cancers each year. Photo © sanjeri / E+ / Getty Images
Controlling silica hazards on aggregate sites and roads
26 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026
> Dusty roads and construction season often go together. Rural, logging, mining access, construction access and temporary worksite roads all require construction and maintenance. Potholes, ruts, soft spots, wash-boarding and washouts must be repaired. Constructing, using or repairing gravel and dirt roads creates dust and some of that dust contains silica. Disturbing silica-containing road surfaces can release fine crystalline silica dust. In the highway, street and bridge construction sector, around 30,000 workers are exposed to silica dust, with most exposures in the high category. Inhaling silica dust can cause serious lung disease and other illnesses, and silica dust is classified as a confirmed human lung carcinogen. In Canada, workplace silica exposure is linked to around 570 lung cancers each year, which includes an estimated 80 cases annually among workers in mining and oil and gas extraction. Other illnesses associated with silica exposure are silicosis, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, scleroderma, sarcoidosis and kidney disease.

DUST CONTROL RESEARCH IS EVOLVING Engineering controls like local exhaust ventilation captures and removes dust at the source. These systems typically use extraction hoods connected to a baghouse dust collector to draw dust away from workers, and work best when equipment is enclosed or partially enclosed. Research and development is ongoing in the field of dust control. A recent example is a compact, self-cleaning dust collector trademarked the Dustinator. Developed in partnership with the National Institute
Air monitoring can verify if dust control strategies are working effectively but can be time consuming and costly to accomplish. The free online Silica Control Tool helps assess and reduce silica exposure without any cost. The Tool guides users through a specific task, job, or activity to estimate airborne silica levels more accurately than visual judgment or guesswork. Using built-in real-world data, the Tool calculates potential airborne silica concentrations based on inputs such

Before the 1980s, road oiling was commonly used to control dust. Waste petroleum products were sprayed on gravel and dirt roads, allowing waste oil disposal and dust suppression at the same time. Ontario was once among the largest users of waste oil for road dust control, applying an estimated 6 million gallons in 1979. Opposition grew after some road oils were found to contain polychlorinated biphenyls (PCBs), heavy metals and other harmful contaminants. Road oiling was eventually banned for dust suppression. Road dust on its own presents several risks in addition to workers' health. Dust clouds can limit visibility and increase the risk of incidents involving vehicles, equipment and workers, especially in mining and forestry. Dust can enter air intakes, engines, brakes and hydraulic systems, causing faster wear and unplanned downtime. It can also affect nearby homes, crops and infrastructure, raising the risk of public complaints and non-compliance, which can result in fines, work stoppages or legal action.

for Occupational Safety and Health (NIOSH), it captures and filters dust generated at bins, tanks and conveyor systems. As part of a hybrid dust control system, it prevents silica dust from escaping into the work environment with an estimated reduction of up to 93 per cent. Dust control should focus on proactive exposure reduction. Personal protective equipment (PPE) is used when residual dust exposure remains, but wearing this equipment can be uncomfortable and may interfere with tasks. Respiratory protection is often required for silica dust exposure. Respirators reduce exposure by filtering contaminated air or supplying clean air to a worker. Typically, options include disposable tight-fitting air-purifying respirators, such as N95s, and reusable tight-fitting respirators made from rubber-like materials with replaceable high-efficiency filters, such as P100, R100, or N100 filters. The appropriate respirator depends on the actual airborne silica concentration. Each worker should be fit tested for any respirator used as part of a respiratory protection program.

Haste makes waste Those companies who prioritize upfront planning and disciplined execution often see long-term success
William Gowdy
In the highly competitive aggregates industry, profitability depends on maximizing resource recovery, minimizing waste and optimizing the use of people and equipment. Three key factors play a critical role in achieving these objectives: upfront deposit assessment, operational scheduling and mine planning. When integrated effectively, these elements can significantly improve efficiency and reduce operating costs throughout the life of a quarry. The foundation of any efficient aggregate operation is a comprehensive understanding of the resources being mined. Upfront deposit assessment involves geological investigations, drilling programs, laboratory testing and resource modeling to determine the quantity, quality and distribution of aggregate within a deposit. While the initial investment in exploration and testing may seem significant, it often delivers substantial long-term savings. A detailed understanding of the deposit allows operators to identify high-quality material zones, predict variations in product characteristics and avoid costly surprises during production. It also supports stronger regulatory applications and reduces the likelihood of costly approval amendments. Better resource knowledge improves reserve estimates, enabling more informed decisions regarding equipment purchases, plant upgrades and capital investments. Accurate deposit assessment reduces uncertainty, improves production forecasting, enhances product consistency and minimizes rehandling or processing of unsuitable material, all of which contribute to lower operating costs. Even the best resource can be inefficiently mined if operations are not properly co-ordinated. Operational scheduling ensures drilling, blasting, extraction, hauling, crushing and screening activities work together efficiently. Well-planned schedules balance production with market demand, reducing excessive stockpiling and material handling costs. Co-ordinated scheduling improves fleet utilization, reduces equipment idle time and minimizes production bottlenecks. Collaboration with sales teams also helps ensure the right products are available when needed. Maintenance planning is another important benefit. By incorporating preventive maintenance into produc-
30 | ROCKTOROAD | SEPTEMBER/OCTOBER 2026
tion schedules, operators can reduce unexpected breakdowns. Planned maintenance typically costs less than emergency repairs and helps extend equipment life while improving reliability. Modern fleet management systems further support cost savings by providing real-time operational data for faster decision-making. Working with company sales departments in advance of projected material demand also ensures that sufficient inventory is available when needed, thereby reducing the frequency of sudden equipment reconfigurations for product switchovers. Mine planning transforms geological information into a practical extraction strategy. A well-designed plan determines the most efficient sequence for resource extraction while considering production targets, haul distances, processing requirements, environmental obligations and future site development. Haulage is often one of the largest operating expenses in an aggregate operation. Strategic mine planning can significantly reduce costs by minimizing transport distances and limiting elevation changes throughout the quarry life cycle. Reduced hauling leads directly to lower fuel consumption, less equipment wear, reduced greenhouse gas (GHG) production and lower labour costs. Mine planning also supports product quality management. By sequencing extraction and blending materials from different areas of the deposit, operators can maintain consistent product specifications while maximizing resource recovery. Effective mine plans also incorporate environmental and reclamation requirements from the outset, minimizing overburden handling, helping manage compliance costs and support sustainable operations. The greatest efficiencies are achieved when deposit assessment, operational scheduling and mine planning are treated as a connected process rather than separate activities. In an industry where margins are often tight, companies that invest in strong upfront planning and disciplined execution are best positioned for long-term success.
