Small and mid-sized paving contractors serve an essential role in infrastructure, tackling challenging terrain and niche projects that larger operations often bypass. The Fremont Lake Road project in Sublette County, Wyoming, demonstrates how a smaller contractor can successfully manage steep grades, tight curves, and cold-weather paving while maintaining high quality standards. Before undertaking such complex work, contractors should understand Who Should Apply for a Building Permit Owner versus contractor responsibilities, especially when public roadways and county infrastructure projects are involved.
Understanding the Project: Fremont Lake Road
Project Scope and Location
Teletractors Inc., based in Pinedale, Wyoming, took on one of its largest projects to date: paving 2.6 miles of Fremont Lake Road in Sublette County. Pinedale sits at an elevation of 7,100 feet, surrounded by three mountain ranges and located approximately 90 miles south of Yellowstone National Park. Sublette County, where approximately 80 percent of the land is public, presented both logistical and environmental challenges that required careful planning and execution. The remote location meant that material delivery, crew coordination, and equipment logistics all demanded additional attention compared to a typical urban paving job.
The road design called for two 13-foot travel lanes and an accompanying 8-foot-wide bike path, a combination that required the paver to handle both standard width paving and narrow-width applications. The project required placement of 14,000 tons of asphalt mix featuring 3/4-inch stone and 70-28 oil. Poor weather meant only half of the bottom lift could be completed before winter arrived, with the 2-inch surface lift scheduled for the following spring when warmer temperatures returned.

Equipment Selection for Challenging Terrain
The Cat AP555E Asphalt Paver
The Caterpillar AP555E Asphalt Paver equipped with an AS2252C Screed handled the paving work on Fremont Lake Road. The paver moved at approximately 20 feet per minute based on a plant output of 160 to 180 tons per hour. Lance Biffle, vice president of Teletractors, highlighted several features that made this machine well suited for the mountain road project:
- Maneuverability: The paver handles tight areas and curvy roads effectively, making it ideal for mountain road applications with frequent direction changes.
- Electric screed heat: Performs excellently in cold weather applications, especially when moving between sections or performing approach work during cold fall conditions.
- Swing-out operator platform: Provides better visibility when performing narrow-width paving such as the 8-foot bike path, allowing the operator to follow a guide line precisely.
- Simplified setup: Fewer components and cords to handle at the start and end of each paving day, reducing setup time and the likelihood of damaging system components.
Windrow Elevator Paving Method
A windrow elevator was used to achieve continuous paving throughout the project. This method offered several distinct advantages on the steep, curvy road where safety and consistent production were paramount:
- Eliminated end-dump truck exchanges, removing a significant safety hazard on sloping terrain where truck stability is a concern
- Prevented the risk of a truck rolling away when negotiating uphill and downhill sections of the winding road
- Allowed the paver to maintain steady forward progress without interruption for truck changes, improving production efficiency
- Reduced segregation risks by maintaining consistent material flow from windrow to paver hopper

Cold-Weather Asphalt Paving Techniques
Temperature Management
Cold fall temperatures at 7,100 feet required significant adjustments to standard paving procedures. The asphalt mix left the plant at approximately 325 degrees Fahrenheit, was placed at around 300 degrees Fahrenheit, and was compacted at roughly 280 degrees Fahrenheit. These temperatures are hotter than typical warm-weather paving specifications to compensate for rapid heat loss in cold air at high elevation.
Belly dump trucks hauled the mix approximately 4 miles from the plant to the jobsite. The crew implemented several critical temperature management practices to ensure the mat stayed workable through compaction:
- Hotter plant output: The mix was heated above normal temperatures before leaving the plant to account for predictable heat loss during transport and placement in cold ambient conditions.
- Close dump proximity: Trucks dumped as close as possible to the pickup machine to minimize heat loss during material transfer between vehicles.
- Cycle time monitoring: The crew constantly balanced plant output, paving speed, and truck cycle time to ensure hot mix upon delivery without causing paver wait time.
- Quick compaction: Rollers stayed immediately behind the paver, with breakdown compaction occurring at approximately 280 degrees Fahrenheit to capture density before the mat cooled.
- Finish temperature management: The mat temperature was about 200 degrees Fahrenheit during finish compaction, requiring rollers to maintain close following distance.
Segregation Prevention
Cold weather heightened segregation concerns during the Fremont Lake Road project, because mix that cools unevenly is more prone to aggregate separation. The crew paid extra attention to proper loading procedures at the plant, ensuring each truck received material in consistent increments. On the jobsite, the windrow elevator helped maintain uniform material composition by remixing the asphalt during transfer. The Cat Paving Operations Training that the team attended the previous winter emphasized segregation prevention techniques including proper head of material in the screed, correct auger utilization, consistent dumping procedures, and maintaining continuous paver movement without stopping.
Compaction Strategy, Quality Control, and Business Lessons
Roller Configuration
Teletractors used two Cat CB54 tandem vibratory rollers in breakdown mode for the Fremont Lake Road project. The rollers operated side-by-side, with each completing five vibratory passes to achieve target density. A smaller finish roller then made two to three static passes to smooth the surface and seal the mat. The close spacing between the paver and rollers was essential given the cold ambient temperatures that accelerated mat cooling.
Joint Compaction Procedures
Proper joint compaction was critical for long-term pavement performance on this project, as poorly compacted joints are the first point of failure in any asphalt pavement. Joints were tacked and placed with approximately 1/2 inch of overlap. The team followed specific procedures for both longitudinal and transverse joints:
- Longitudinal joints: The first vibratory pass was made approximately 1 foot inside the joint, with all subsequent passes on the joint itself to achieve uniform density across the joint zone.
- Transverse joints: A smaller roller ran side-to-side directly on the joint for thorough compaction without disturbing the adjacent mat.
- Quality verification: All joint work was checked with a straight edge to ensure a smooth, uniform surface free of bumps or depressions.
The Role of Training in Quality Outcomes
Three Teletractors team members attended Cat Paving Operations Training in Florida the winter before the Fremont Lake Road project. Biffle credited this training with building the confidence and technical knowledge needed to take on larger, more complex projects. The training covered segregation prevention techniques, proper material handling procedures, and operational fundamentals that proved essential when working under cold-weather time constraints. Understanding Contractor Roles and Responsibilities in Construction includes recognizing when specialized training is necessary to deliver quality work that meets project specifications.
Scaling from Small Projects to County Roads
Teletractors followed a deliberate progression in its paving operations. The company started with parking lots and driveways, advanced to city streets, and eventually took on county road projects. This step-by-step approach allowed the team to build skills, refine processes, and invest in appropriate equipment before tackling larger, more complex work. The experience gained from smaller projects provided the foundation for successful execution of the Fremont Lake Road paving job, which was both the company’s largest general contracting role and its biggest paving project to date.
Diversification as a Business Strategy
Operating in a small town with approximately 2,000 residents requires diversification to maintain steady work throughout the construction season. Teletractors handles underground utility work, general excavation, road construction, sand and gravel sales, and asphalt sales and paving. This broad service offering provides steady work across multiple revenue streams, allowing the company to invest in specialized equipment and training even during slower periods. Contractors evaluating their own business growth should learn How to Find the Right Contractor Home Construction approaches and adapt similar principles of service diversification to commercial and infrastructure work.
Key Takeaways for Paving Contractors
- Invest in training before taking on bigger projects. The Cat Paving Operations Training directly improved Teletractors’ ability to handle cold-weather paving on steep terrain and gave the team confidence to pursue larger work.
- Choose equipment that matches terrain conditions. The maneuverable paver with electric screed heat and swing-out platform was ideal for mountain road work with tight curves and varying pavement widths.
- Adapt temperature management to weather conditions. Hotter mix temperatures and closer truck spacing compensated for rapid heat loss at high altitude in cold weather, maintaining workability through compaction.
- Use appropriate material handling methods. The windrow elevator eliminated safety risks on slopes while maintaining continuous paving and reducing segregation in the mix.
- Verify quality at every stage. Straight-edge checks on joints, proper overlap on longitudinal seams, and consistent roller patterns ensured pavement durability despite challenging cold-weather conditions.
The Fremont Lake Road project demonstrates that small and mid-sized contractors can successfully tackle challenging terrain and weather conditions by committing to fundamentals, investing in appropriate equipment, and pursuing specialized training. These principles apply whether paving mountain roads in Wyoming or handling any demanding paving application where quality and safety are the primary objectives.
