I
have a confession to make. Four years ago, when I started as your editor, I didn’t know anything. I’m not just talking about asphalt or pavement. I didn’t know how to be a “professional” editor either. I was a published author and I had been the editor for a poetry and art magazine, far from the sort of rigor and rules of being a “B2B” editor in a corporate work environment. Because of this, since day one, I have been on a mission. My first mission was to learn everything I could about the asphalt industry, about pavement maintenance, about mix design, rolling, paving, aggregates, QC, etc. The more I learned, the more areas of the job there seemed to be, and quickly I discovered that being in the field was the only real way to properly educate myself. So, I got out into the field as much as possible, and that, my friends, was where I fell in love with the industry. My second mission was as visible as it was glamorous: learning how to be a professional editor. This journey wasn’t posted online as content, funny videos, or podcasts – this played almost entirely behind the scenes as my boss (The great Marina Mayer) helped me through all of the growing pains. I hustled as much as I could, and only one time did I have to scrap an article because it wasn’t up to muster. Only the closest of readers might have noticed my growth in this regard through the quality of my articles over the last four years. For me, when I look back at my earlier pieces, it’s kind of shocking. But I had a third mission, an unspoken one. I secretly wanted to see if I could get away with being able to bring into my work here some of what I am passionate about.

Aesco-Madsen Eco-Foam 2 Additive System ALmix INSIGNIA VISION ALmix IV bridges the gap via the Insignia Cloud, giving your management team a live look at the facility’s health and output. In the high-stakes world of asphalt production, information is the lifeblood of your business. Insignia Vision, or ALmix IV, is designed to deliver a continuous, high-speed infusion of plant data directly into the heart of your headquarters. It provides a constant stream of operational intelligence, ensuring your leadership team has the “vision” to lead with precision. ALmix IV bridges the gap via the Insignia Cloud, giving your management team a live look at the facility’s health and output.
Growing rapidly in popularity over recent years has been a practice known as warm mix, which involves the injecting of water into hot asphalt cement (A/C) just before it reaches the aggregate with which it is to coat. When the A/C and water mix, a unique foam is produced which can effectively bind with aggregate material that has been heated to temperatures notably lower than the aggregate temperatures required for traditional hot mix asphalt. The many benefits of this process include saving on fuel consumption as well as reducing greenhouse gas emissions. It is hence no surprise that one of Aesco Madsen’s most popular additive systems is their Eco-Foam II warm mix system equipped with it’s static inline vortex mixer. As it’s name suggests, the static inline vortex mixer is placed inline with the asphalt cement piping so that the A/C flows through the mixer. This stationary component is considered static because it is able to effectively mix the asphalt cement and water without the use of moving parts.
Troxler Moisture Measurement System Model 3630 Measures moisture content as the aggregate moves through the plant. The MMS Model 3630 uses proven nuclear technology to continuously monitor moisture in your aggregate mix. The moisture measurement occurs as the mix moves through the plant on the conveyor belt. There is no physical contact with the aggregate mix or belt. The system provides a continuous reading of the moisture content. The moisture content, combined with the knowledge of the mass proportions of the other components in the mix, provides you with a precise and reliable moisture content of the aggregate.

e’re in a new era — not an entirely digital era where the type or size of iron doesn’t matter, but an era of adoption. Whether a contractor integrates machine control or optimizes their fleet by mining machine datasets, contractors are looking to gain an edge on efficiency by onboarding a total jobsite solution, including software and hardware advancements. After meeting with WIRTGEN GROUP, other original equipment manufacturers (OEMs) and contractors, it’s clear that we have the skill, iron and technology to revitalize the nearly 70-plus-year-old interstate

highway system, despite any unforeseen challenges. As many crews start work on mega highway projects, we in the industry recognize we’re entering a transitional period as AI machine learning progresses. Many of us are watching these developments, dreaming about the Jetsons-like capabilities — perhaps the ability to pave with the precise mix at the right time based on previous models? However, we’ll only be able to harness this information if we follow an adoption strategy to prepare today for tomorrow’s data and machine learning tools. I’ve learned from contractors that the successful adoption of a total jobsite solution happens in phases: understand, adjust and integrate. By going through the phases, crews move from dreaming to doing when it comes to innovative equipment hardware and software solutions. Let’s review what each phase entails.
1
UNDERSTAND DATA WITH A FLEET MANAGEMENT SYSTEM Nearly a quarter of a century ago, OEMs like John Deere added JDLink Connectivity to collect GPS data points and feed them into a fleet management system (FMS) like John Deere Operations Center. “The first use case of telematics was monitoring the location and production hours,” said Larry Herman Jr., RDO Equipment Co.’s telematics support manager. “During the last 20 years, telematics data has expanded to include Expert Alerts, optimizing preventative maintenance scheduling and keeping machines working when needed.” Since John Deere and the WIRTGEN GROUP joined forces, they’ve been transitioning WITOS FleetView into the Operations Center so
www.ForConstructionPros.com/Asphalt

fleet managers view data from all their machines — pavers, wheel loaders or skid steers — all in one FMS. Today, most Wirtgen machines are built with the Operations Center, a user-friendly software with various applications, such as Machine Analyzer or Wirtgen Performance Tracker. The Operations Center’s applications can complement surveying equipment from other OEMs, like Topcon Positioning Systems. In reality, most projects include mixed fleets, so a total jobsite solution consists of many iron colors but one data collection system. Equipment fleet managers make data-informed decisions every day. When they view their equipment fleet’s data in a consolidated dashboard, they can pinpoint iron insights — like an opportunity to swap a larger wheel loader for a smaller one on a particular job to use less fuel while removing asphalt or concrete debris.

REVIEW DATA, PERFORMANCE, THEN ADJUST IRON Herman Jr. said every contractor wants to monitor their machines’ performance and plan preventative maintenance as much as possible. “A user-friendly FMS like the Operations Center helps fleet managers to understand how many miles were paved and the total cost of inputs at the end of each week,” Herman Jr. said. When data such as GPS, compaction, or fuel consumption is recorded in the contractor’s preferred FMS, the fleet manager can review the various datasets, including grading information. “Surveying equipment like lidar (light detecting and ranging) captures real-time grading GPS data points each week,” said Cody Wagner, RDO’s roadbuilding technologies product manager. Like dirt, precision in roadwork requires experience, datasets and familiarity with the necessary machinery. To do this, contractors create a finely tuned survey and data collection system through their FMS and add the right equipment model for their projects. For example, Vögele’s Dash 3 pavers
www.ForConstructionPros.com/Asphalt
ACON0926_12-13_Tech_BN.indd 13
include a mobile feeder and additional screed. When the Vögele paver operator receives real-time survey info, they can adjust feeder speed or screed level. Fleet managers partner with operators to review datasets and identify where they can make changes. A paver’s mix can cool for many reasons, including inconsistent speeds, screeds or stops. Wagner shared that one Minnesota contractor used a Pavermounted Thermal Profiling (PMTP) method to record the mat’s surface temperature behind their paver immediately. They fed this data into their online reporting system and partnered with Department of Transportation (DOT) officials to determine its realtime pavement segregation. With this information, this contractor was able to reduce rework and fuel costs.

INTEGRATE SOFTWARE APPLICATIONS WITH AN EQUIPMENT PARTNER Fleet managers, operators and technicians partner to develop machine monitoring technology solutions for the contractor’s equipment fleet. “RDO developed its telematics team to partner with contractors and drive a collective understanding of WITOS and Operations Center solutions,” said Jake Livingston, RDO’s director of connected support. “With so much data flowing in from connected machines, we’re always working to shed light on the opportunities to turn data into action.” Some dealers, like RDO, offer 3D modeling services or training. Data points can be fed into a CAD (computer-aided design) system to create a digital twin of the paving project. DOT quality inspectors often
review the digital twin of the road’s progress to discuss optimal compaction. After a paver’s initial pass, DOT officials and contractors determine if the mat requires another pass to increase compaction. Fleet managers may opt for vibrating (VV) oscillation (VO), combination (VT), or pneumatic-tire (TT) drums on a Hamm tandem roller, depending on the required impaction force. Rollers like these, plus integration with GPS and surveying data, allow operators to change compaction force periodically. Additionally, support teams train fleet managers and their operators to enable automated field service requests. Contractors discuss machine health monitoring solutions with their trusted dealer, so remote support professionals monitor Hamm roller’s hydraulic pumps or vibration motors’ calibration. This ability becomes even more valuable when contractors work on remote jobsites and field technicians require advanced notice to travel and perform preventative maintenance. Depending on the project, like a tollway road restoration, the DOT may require in the bid for the contractor to maintain the road up to 10 years after the initial project is completed. Also, many state or countyfunded projects can have bonuses for accurate density. With the datasets, models and machine monitoring data, contractors have the information to illustrate that their highway restoration will last for years. Adopting a total jobsite solution for your jobsite will require time, team members and trusted experts. However, when contractors understand their equipment fleet’s data, they can adjust machines based on its performance and then integrate machine monitoring and modeling software. Contractors who adopt a total jobsite solution prepare their team for futuristic machinelearning solutions that may be closer than we think. by Dennis Howard is senior vice president of Roadbuilding and Minerals at RDO Equipment Co., where he also leads RDO’s Wirtgen Group business.

UNDER THE STADIUM LIGHTS: A Perspective On Proficiency Testing
AdobeStock_andrew_shots
When a proficiency sample box arrives, most labs clear a senior technician’s schedule and treat it like game night.
I
was on a plane the other day, chatting with a high school soccer coach who happened to be sitting next to me. His excitement to talk about coaching seemed palpable, so I listened. He described an interesting difference between practice sessions and game day. During routine practice sessions, players sometimes go through the motions while completing repetitive drills. However, when the stadium lights come on, the same players often play with remarkable precision. They hadn’t suddenly become different players; the spotlight simply changed their operational environment. As I listened to the coach, I realized laboratories face a similar challenge.
14 ASPHALT CONTRACTOR SEPTEMBER 2026 ACON0926_14-19_Production_BN.indd 14
A proficiency sample is the laboratory equivalent of game day. But what happens if a laboratory prepares differently for the game than it does for practice? In a construction materials testing laboratory, this gap between routine operations and proficiency testing is a tightrope every manager must walk. Daily practice represents the routine high-volume testing of aggregate and asphalt samples from various projects while game night represents the proficiency sample used to evaluate laboratory performance. The challenge comes from balancing two competing priorities: routine testing demands and mandatory compliance work.
Like the soccer team, technicians are not necessarily underperforming because they lack discipline or competence. Instead, the shift in focus and attention can affect how they approach the task. Although lab managers dread seeing low z-scores, they can provide valuable opportunity to identify hidden process weaknesses before they grow into larger problems and begin to affect accreditation. Repeated low ratings may ultimately result in the suspension of a laboratory’s credentials until the issues are resolved. Because the stakes are so high, the arrival of a proficiency sample box creates a major logistical crossroads.

GAME NIGHT OR JUST ANOTHER SAMPLE? When a proficiency sample box arrives, the temptation to treat it as a highstakes championship game is understandable. Laboratory managers are inclined to assign the work to a senior technician by clearing their schedule of all daily work and letting them focus only on the proficiency sample. This approach would likely result in a favorable z-score, but it may be capturing the laboratory’s optimized performance rather than normal operating capability. The other option is to add the proficiency sample into the daily workflow along with the truckloads of samples waiting to be tested. This does not mean treating it casually. It means applying the same documented procedures, quality controls, and equipment requirements that should exist for every other sample tested in the laboratory. The difference is that technicians must work on proficiency samples while managing the daily demands of routine testing. This choice of how the proficiency sample is handled raises an important question: what exactly is proficiency testing supposed to measure? Is it intended to demonstrate the laboratory’s absolute best performance under ideal conditions, or its ability to consistently produce reliable results through its established processes? WHY LOW SCORES HAPPEN IN A BUSY LAB When a low performance rating occurs in this everyday environment, it is rarely a sign of subpar work or technicians intentionally taking shortcuts. Instead, a low z-score may reflect the influence of normal operational conditions, competing deadlines, shared resources, workflow limitations, and so on.
16 ASPHALT CONTRACTOR SEPTEMBER 2026 ACON0926_14-19_Production_BN.indd 16
A good example of this is a proficiency sample that may come with instructions to condition an asphalt mix sample in accordance with AASHTO R30. On game night, the oven is exclusively used for proficiency sample testing and the door stays shut for the entire duration. However, in a busy lab with technicians performing multiple tests, the same oven is often shared for other tasks. As technicians open and close the door, the temperature stability may be affected, potentially influencing the final test results. This illustrates that the issue is not necessarily technical competency. Instead, it reveals how the design of a laboratory’s scheduling and operating system can influence the consistency of test results. In other words, the proficiency sample did not create this vulnerability; it exposed a vulnerability that existed within the laboratory’s existing workflow. THREE PLACES TO LOOK FOR ROOT CAUSE A low z-score is a valuable indicator that can reveal weaknesses within a lab’s processes. To uncover the source of the problem, a lab should conduct a thorough root cause analysis by examining three categories of potential causes. • Technical causes include issues such as using out-of-calibration equipment or procedural errors. • Operational causes include issues such as shared equipment, staffing issues, workflow issues, or scheduling conflicts. • Human causes include issues such as training gaps, fatigue, or communication breakdowns. COACH THE SYSTEM, NOT THE PLAYER When a root cause analysis uncovers an issue like a fluctuating oven temperature,
a manager has a choice. Some managers might simply focus on the technician performance and issue a generic reminder to “follow the spec.” Others may use the opportunity to examine whether there is an underlying issue that is contributing to the low rating. A good coach does not simply criticize a player for missing a pass. They examine whether practice conditions, communication, positioning, or training methods contributed to the outcome and restructure practice sessions to create better habits. Similarly, an effective manager addresses the systemic bottlenecks. Perhaps designating a single, undisturbed oven exclusively for critical conditioning windows is the way to go. The goal is not to assign or apportion blame, but to identify and remove obstacles that can make achieving consistent results easier. At the end of the day, both a coach and a laboratory manager share the same goal, which is to close the gap between daily practice and game night. A proficiency sample should not become a special event to achieve a favorable z-score. Instead, it should provide insight into whether laboratory’s established processes can produce reliable and repeatable results. At the same time, daily testing shouldn’t be vulnerable to poor workflow and impossible deadlines that can influence test results. A strong quality system doesn’t expect technicians to suddenly elevate their performance just because the stakes are higher. Instead, it creates conditions that allow them to perform at that same high level every day. Just as great coaches build winning habits during practice, great laboratory managers build systems that make reliable performance routine – both during everyday testing and when the stadium lights come on.

FACE OF THE INDUSTRY | By Allyson Sherrier, Managing Editor
Cold Recycling’s Biggest Champion Wants To Change How Roads Are Rebuilt After discovering cold recycling nearly a decade ago, Jessie Boone made it her mission to help contractors and road owners rethink pavement rehabilitation.
F
or more than a decade, Jessie Boone has been on a mission to change how the industry thinks about rebuilding roads. Whether she’s speaking to contractors, transportation agencies or engineers, her message is consistent: there are better, more sustainable ways to rehabilitate pavements, and the industry can’t afford to ignore them. As Market Development Manager for Recycling Products at Wirtgen Group, Boone travels throughout the United States and Canada promoting cold recycling technologies and helping road owners understand their long-term benefits. Her enthusiasm for the technology is contagious, but her journey into the asphalt industry was anything but conventional. For Boone, the road to becoming one of the asphalt industry’s most passionate advocates for cold recycling was anything but planned. “I was actually going to school to be a dentist,” Boone said. After deciding dentistry was not the right fit, a friend encouraged her to look into the Concrete Industry Management (CIM) program at Middle Tennessee State University. Boone quickly discovered a field that combined science, engineering and business in a way that resonated with her. “It was a really good foundation to build a career on,” she said. After graduating during the economic downturn of 2008, Boone worked in quality control and sales in the ready mix industry and then in the cement industry before finding her true calling in pavement rehabilitation.

Jessie Boone
“One thing led to another, and somehow I fell into recycling asphalt pavements back in 2015,” she said. “I really fell in love with the whole technology.” That passion has only grown over the last decade. Today, Boone spends roughly half the year on the road promoting cold recycling technologies, including Full Depth Reclamation (FDR), Cold In-Place Recycling and Cold Central Plant Recycling. Her work ranges from presentations and workshops to jobsite demonstrations and open houses. “Every day is different,” she said. “My job is like a snowflake. Not one day is the same.” LEARNING THROUGH CHALLENGES Boone credits much of her professional growth to the challenges she faced early in her career. Graduating during the recession meant competing for limited opportunities. Working in technical,
male-dominated environments often required proving herself repeatedly. “There were times when I was belittled and talked down to, and downright disrespected,” Boone said. “But I would think to myself, this too shall pass.” Those experiences helped develop the resilience she now shares with younger women entering the industry. Boone encourages them to stand up for themselves, recognize their value and refuse to accept inappropriate treatment. “It is so easy as a female in this industry to dismiss some of the behavior that you encounter,” she said. “Sometimes you’ve got to put your foot down and say enough is enough.” At the same time, she believes the industry offers tremendous opportunities for women willing to step outside traditional career expectations. “Don’t dismiss construction just because you think that’s a man’s job,” Boone said. “I’m here to tell you, you can do it.”

A PASSION FOR RECYCLING Ask Boone what excites her most about pavement recycling, and the answer comes quickly. “The equipment is badass,” she said with a laugh. She vividly remembers her first encounter with a piece of equipment during a project in 2015. Seeing the machine in action sparked immediate fascination. “I’ll never forget pulling up on that jobsite and seeing that Wirtgen reclaimer,” Boone said. “I’d never seen one before in my life, and I was taken aback by just the scale of it.” The appeal goes beyond the machines themselves. Boone emphasizes that cold recycling offers a practical solution to many of the industry’s infrastructure and sustainability challenges. “They need to be in every DOT toolbox in some shape or fashion.” OVERCOMING BARRIERS According to Boone, the greatest obstacle facing wider adoption of cold recycling is not technology — it’s education. Most civil engineering programs still devote little attention to recycling technologies, leaving graduates unfamiliar with the applications. Boone also sees hesitation among transportation agencies that may be reluctant with new approaches, even those with long-term benefits. “What cold recycling does is address the cause of the symptoms, not just the symptoms,” Boone said. Through Wirtgen’s partnership with organizations like the Asphalt Recycling and Reclaiming Association (ARRA) and The Southeast Cement Promotion Association, Boone continues pushing for greater awareness of these technologies across North America. INSPIRING THE NEXT GENERATION Beyond her professional responsibilities, Boone is committed to helping young women discover careers in construction materials and engineering. She has helped organize outreach events through MTSU’s CIM program, introducing middle school and high school students to everything from concrete placement to welding. The goal is simple: expose students to career paths they may never have considered. “There are more girls just like me, they’ve just not been challenged to explore other careers,” Boone said. She has seen encouraging growth in the number of women entering the CIM program and hopes that trend continues. CHANGING THE CONVERSATION As Boone considers the future of the industry, she remains optimistic. She believes younger generations are increasingly aware of the importance of resource conservation and sustainable construction practices. She hopes that awareness will help drive innovation and broader acceptance of technologies that make better use of existing materials. “We’ve got to start doing better than previous generations,” Boone said. “Sustainable construction is a great place to start.” That future starts with education, advocacy and a willingness to challenge the status quo.

JOBSITE INNOVATIONS
Quality Control Doesn’t End When Asphalt Is Installed People are increasingly asking a harder question, and it isn’t about how the job looked at handoff, it’s about how it will look in ten or twenty years.
T
en years ago, project quality was largely measured by what happened on the day construction ended: whether the pavement had a smooth surface, properly placed asphalt, acceptable density, strong compaction numbers and clean joints. If a project met specifications and looked good at handoff, it was generally considered a quality job. No one has abandoned that standard. However, today, the conversation around quality has expanded toward whether the pavement actually holds up. REDEFINING “QUALITY CONTROL” Owners, facility managers and contractors are increasingly evaluating pavement based on its life cycle costs rather than its initial installation price. A parking lot or roadway that still performs 15-20 years after installation is complete is the result of quality workmanship during construction, combined with planning, preservation and consistent maintenance throughout the pavement lifecycle. Many contractors understand how pavement fails but still leave owners without a clear maintenance plan once construction is complete. Not only is it a part of the job that gets skipped too often, but it is a missed opportunity. A simple maintenance schedule—sealcoat this year, crack fill by this date, watch for these warning signs—can significantly extend pavement life. Another key is selecting the right asphalt mix based on a thorough understanding of existing site conditions. That’s why the definition of quality control has expanded.
WHY CHOOSING THE RIGHT MIX IS ESSENTIAL Choosing a lower-cost mix may reduce upfront costs, but it can also result in pavement that deteriorates prematurely if the material isn’t suited for the application. In that respect, quality control means making informed decisions upfront that maximize long-term pavement performance. It is also important to have appropriate testing and planning before starting the work. Having a full understanding of the pavement by gathering data through coring existing pavement to determine its condition as well as its thickness is important. Testing and planning at a site influence decisions ranging from milling depth to overlay design. The more information collected upfront, the better prepared a project team is to communicate realistic expectations, find the correct solution and deliver a pavement that will have lasting performance.
better understand the entire scope. Being honest about the things that aren’t known is also an important part of the process. Even with detailed planning, there are conditions beneath the surface that often can’t be confirmed until the work begins. That type of conversation shouldn’t be avoided just to win the work. Being AdobeStock_95434784
TRANSPARENCY IS PART OF QUALITY Quality control also depends on transparent conversations before work begins. Sometimes that means explaining why one mix is more expensive than another, or why one proposal might come in higher than a competitor’s bid because it specifies a premium mix versus a lowercost alternative. On paper, it may be difficult for an owner to justify that difference. If the owner’s goal is to have the pavement perform over time, and there is a transparent conversation explaining why those decisions matter, it can help the customer
32 ASPHALT CONTRACTOR SEPTEMBER 2026 ACON0926_30-31_Jobsite_Bn.indd 32
8/27/26 9:22 AM
upfront about potential issues and encouraging owners to budget for unforeseen conditions helps prepare them for what may happen once construction begins. DON’T IGNORE WARNING SIGNS Asphalt pavement rarely fails without warning. Traffic, weather and water infiltration leave visible signs that can help provide owners with insight into how the pavement is performing below the surface. Sometimes, the smallest defects deserve the most attention. A crack, for example, may not look like much, but it gives water a path into the pavement structure. Once water reaches the base, the deterioration below the surface has already started, even if the actual surface still looks good.
www.ForConstructionPros.com/Asphalt
ACON0926_30-31_Jobsite_Bn.indd 33
Waiting until a pothole appears and creates a liability risk almost always means the problem has been developing for months or even years. At that point, what could have been a simple low-cost crack sealing or drainage correction often becomes a much larger repair. Preventive maintenance is part of quality control. It involves addressing early warning signs before they become real structural problems, and before they lead to a complete overlay or full rebuild. It includes performing routine inspections, crack sealing and sealcoating done at the right time and correcting drainage issues to keep water out of the pavement. The industry is shifting toward greater accountability for long-term pavement performance, not simply whether a project met specifications on the day it was completed.
Pavement management software is becoming more common among private owners, not just public agencies. Contractors are going to be expected to hand over maintenance guidance as part of the job, not as an add-on service. Data drives a lot of this. The easier it gets to track how pavement holds up, the harder it will get for contractors to hide behind that idea that it looked fine when they left. Quality is no longer defined by how pavement looks on the day construction ends. It’s measured by how well that pavement performs years later. Contractors who embrace that mindset will be better positioned to deliver lasting value and build stronger relationships with their customers. by Marc Navetta, Vice President of Customer Engagement, ASI Paving

PRESERVATION & SUSTAINABILITY

Rethinking Fog Seals
Over the last decade, fog sealing has changed in big ways.
N
ew rejuvenators and polymermodified emulsions are improving performance. At the same time, owners are using fog seals differently – earlier in the pavement life cycle, on repeat intervals, and as part of a broader preservation plan instead of a one-off treatment. The result is a shift worth paying attention to. Fog seals are moving from a low-end maintenance option to a more deliberate tool for extending pavement life and smoothing out maintenance budgets.
THE OUTDATED PERCEPTION Use of fog seals, along with other asphalt surface sealing concepts, gained momentum after the oil crisis of the 1970s. Maintaining rather than replacing pavements became a priority as the cost of asphalt used in pavements soared. Long viewed as a low-cost surface treatment for low-volume pavement, perceived fog seal product limitations have persisted over time even as formulations, applications and pavement preservation philosophies advanced. The reputation comes, in part, from how fog sealing previously was applied – to structurally failed pavement (not an ideal candidate), under poor weather conditions (overcast or humid day with high moisture takes longer to cure) or without essential traffic control (necessary to keep traffic from driving through the application before it has time to cure). Financial and industry culture issues may play a role in the perception problem as well. Fog sealing is inexpensive compared to overlays or mill-and-fill work, so it can be dismissed as low-tech or less important, favoring treatments that are more visible, capital-intensive or structurally oriented. A philosophy shift, from fixing failed pavement cheaply to preserving newer pavement before deterioration accelerates,
34 ASPHALT CONTRACTOR SEPTEMBER 2026 ACON0926_32-33_Pres_BN.indd 34
is gradually overcoming misconceptions about fog sealing performance today. Like sunscreen, fog sealing should be applied before too much pavement damage has occurred. In fact, to be cost-effective, it should be applied before most project decision makers typically consider its use. It does not add structure or enhance a pavement’s load-bearing capacity as its function is to prevent the pavement surface from oxidizing – drying up and creating micro cracks which lead to bigger cracks, allowing more water to come into the pavement matrix and break down its components. The initial black color of fog sealing can fade in as little as six months, but the protective layer of emulsion continues to do its job of keeping the surface moist over a much longer period of time. A CHEMISTRY-DRIVEN PRESERVATION TREATMENT In the continuum of pavement preservation, rehabilitation and reconstruction, fog sealing lands squarely in the preservation category. No longer thought of as just a surface-sealing solution, developments in the last 10-15 years have revolutionized fog sealing as an engineered pavement-preservation system focused on oxidation control, binder chemistry restoration and lifecycle extension. Today, users recognize the difference between conventional and rejuvenating fog seals that are designed to penetrate oxidized binder, restore viscoelastic properties, slow oxidation, improve flexibility and reduce brittle cracking. While rejuvenating fog seals still use asphalt emulsion technology, they also have agents designed to penetrate aged asphalt binder and restore flexibility and often include polymer modification to improve durability, adhesion and traffic performance, especially on highervolume roads.
With improvements in formulation came higher standards in application discipline with tighter guidelines on nozzle configuration, distributor calibration, pavement temperature, curing conditions and traffic reopening. The most recent innovations in fog sealing have led to faster-curing, trackless formulations and friction-conscious designs with standard application methods now using GPS-guided distributor calibration, precise spray bars, lane-by-lane traffic staging and friction monitoring. MEETING ESG GOALS Some fog seal attributes have not changed since the early days – it can be applied quickly as a lower cost preventative maintenance technique. Coupled with all its modern innovations, this application meets several core asset management objectives: • extending pavement service life • delaying overlays and reconstruction • improving lifecycle cost efficiency • smoothing long-term capital spending • preserving pavement cond. indexes • reduce deferred maintenance backlogs For ESG initiatives, compared to reconstruction fog sealing has a relatively small material and carbon footprint because it works with the existing pavement structure instead of replacing it. This requires less asphalt binder, fuel, virgin aggregate, trucking, construction equipment and demolition. Applied correctly and at the right pavement condition, fog sealing can help delay more expensive overlays and rehabilitation. Applied too heavily or after major distress develops and it can reinforce the old industry complaints about slickness, tracking and short-lived performance.

THE LAST EXIT N Felixpeopleimages.com_AdobeStock
Stronger Workforce Planning Recent immigration policy confusion is a reminder that contractors benefit from diversified hiring.
F
ew industries understand unpredictability better than construction. That’s why recent confusion from the U.S. Citizenship and Immigration Services (USCIS) over an “adjustment of status” memo is important to break down and understand. It’s not just an immigration policy issue, for construction companies it reveals the critical nature of workforce planning and strategies that can survive the most confusing moments. When it comes to employing foreign workers, understanding how lawful tools like the EB-3 visa can be leveraged to fill hard-to-fill, year-round roles, long-term planning becomes even more important. USCIS issued their memo in May, advising that adjustment of status should be granted only in “extraordinary circumstances.” As written, that suggested some foreign workers already in the United States could be pushed out of the country to pursue green cards through consular processing in their
CLASSIFIEDS
home countries instead. Then, a week later, the Department of Homeland Security (DHS), which oversees USCIS, tried to clear up the confusion through media statements rather than putting out a clear follow-up version of the memo, further confusing industry leaders. Those statements left employers, workers and immigration lawyers trying to sort out what had actually changed, adding more uncertainty to an industry that already has more than enough. CONFUSION IS A PLANNING PROBLEM If a lawful workforce pathway suddenly becomes harder to predict, contractors are left trying to plan around more instability. It raises concern over whether a worker will be able to remain in the country and continue the same path, or if that person will have to leave and complete the process abroad. It also leaves industry professionals wondering whether the process will become more or less predictable. Labor is already tight, so more uncertainty around legal workforce pipelines can be felt quickly throughout an operation. We see it in hiring slowdowns, more cautious managers and long-term staffing plans being disrupted. This recent “adjustment-of-status” miscommunication does not mean the broader pipelines for foreign workers, like the EB-3 visa, have been closed. They remain very viable options employers can and should continue to consider. The most affected group is that of the workers already in the U.S. who hoped to gain their green card stateside using adjustment-of-status. That’s different from saying the broader employment-based immigration path has been closed, because it hasn’t. For many workers, especially those planning to use consular processing abroad, it remains intact. A STRONGER WORKFORCE PLAN A solid plan should combine stronger domestic recruiting, better retention mechanisms, apprenticeships and training, more clear pathways for advancement, along with lawful immigration tools, together into one broad model. The goal is not to replace domestic hiring, but to make the workforce strategy as comprehensive as possible, helping to reduce the uncertainty that is already part of doing business. The reality is that builders cannot control the uncertainty coming out of Washington, but they can control how prepared they are to absorb it. With labor shortages already hitting the industry hard, it puts businesses in a better spot to have more resilient and broad staffing strategies instead of waiting for a single pipeline to hold it all together. by John Dorer is CEO of EB3.Work
