Exceptional asphalt paving does not happen by accident. It requires a deliberate combination of skilled people, well-maintained equipment, and disciplined processes that together produce roads that stand the test of time. When state and national asphalt pavement associations recognize outstanding projects, they highlight contractors who have mastered this balance. The Pavement Construction and Asphalt Equipment a Complete Guide demonstrates how integrating the right machinery with careful planning leads to superior results. The Oklahoma Asphalt Pavement Association (OAPA) 2021 award recipients provide a powerful case study in what a culture of excellence looks like in practice, with Cummins Construction Company winning in three of six categories including the Full Depth award for their work on US-183/US-270 in Woodward County.
The Foundation of Excellence: People-First Company Culture
At the heart of every award-winning paving project is a team that genuinely cares about the outcome. Cummins Construction Company operates as an employee-owned firm, and this ownership structure directly influences the quality of work produced in the field. When every crew member understands that they have a stake in the company reputation and financial success, the level of accountability rises dramatically.
Employee Ownership Drives Pride in Workmanship
Employee ownership creates a direct link between individual effort and company performance. Crew members who are part-owners of the business take pride in every mat they lay down. They go the extra mile to achieve a smooth ride because they know the company reputation and their own returns depend on it. This pride manifests in the attention to detail that separates good paving from great paving.
Key benefits of an employee-owned paving operation include:
- Higher retention of experienced crew members who understand company standards
- Greater willingness to invest time in quality control and finish work
- Reduced turnover saves training costs and preserves institutional knowledge
- Crew members proactively identify and solve problems before they affect quality
- Shared commitment to safety and equipment care across all team levels
Investing in Operator-Approved Equipment
A culture of excellence means listening to the people who operate the equipment every day. When Cummins equips their crews with the machines they prefer, productivity and quality both improve. The company runs eleven BOMAG pavers based directly on operator feedback. The reasoning is straightforward: operators who are comfortable and confident with their equipment produce better results. They understand the machine capabilities, can troubleshoot issues quickly, and maintain consistent mat quality across long paving days.
This approach recognizes that equipment value is measured not just by purchase price or depreciation schedules but by the quality of the finished pavement. When operators trust their machines, they push harder for excellent results rather than simply completing the minimum required work.
Phased Construction: Managing Complexity on the US-183/US-270 Project
The US-183/US-270 project in Woodward County exemplifies how thoughtful phasing transforms a complex highway widening into a manageable operation. This five-mile stretch of roadway serves as the western corridor for truck travel from Kansas through Oklahoma to I-40, carrying an estimated 4,900 vehicles per day with a projected 2038 volume of 7,200 vehicles per day, 33 percent of which are trucks. The project had been in the planning stages since 1998, with widening officially restarting in 2016. Cummins bid and began construction in late 2019.
Breaking the Work into Manageable Phases
Dividing the project into three distinct phases allowed the team to maintain traffic flow throughout construction while completing complex earthwork and paving operations:
- Phase 1 focused on drainage structures, adding new lanes, and detouring traffic to set the stage for mainline work
- Phase 2 involved construction of two entirely new lanes, including soil stabilization and paving, while keeping the existing roadway open
- Phase 3 addressed reconstruction of the old lanes and additional drainage work after traffic had been shifted to the new pavement
By completing the new lanes first, crews maintained two-way traffic throughout the project duration. This approach significantly reduced delays for the traveling public and, just as importantly, kept paving crews out of moving traffic during active construction.
Earthwork and Stabilization Requirements
The scale of earthwork on this project was substantial. Construction included removing 316,000 cubic yards of material. During Phase 2, a 4 percent cement soil stabilization treatment was applied to set the base before any paving began. A subcontractor placed 165,000 square yards of stabilized subgrade across the two new lanes, creating a uniform foundation capable of supporting heavy truck traffic for decades.
Equipment Strategies That Deliver Superior Ride Quality
The equipment choices made on a paving project directly influence the final ride quality, and the US-183/US-270 project demonstrates how deliberate equipment strategies produce exceptional results. From pavers to material transfer vehicles to rollers, every machine played a role in achieving award-winning smoothness. Understanding the Road Construction and Asphalt Paving Equipment Machinery for highway infrastructure helps contractors make informed decisions about their fleet composition.
Custom Drag Skis and Sonic Averaging Systems
One of the most impactful equipment decisions on this project was the use of 60-foot drag skis paired with Topcon sonic averaging systems (SAS). A custom drag ski built by the Cummins team was fitted to the primary CR462 paver. The combination of a long reference ski and electronic averaging stretches any deviations in the road surface over 60 feet instead of the standard 24 feet. This simple but effective technique dramatically improves the final ride by reducing the impact of localized bumps and dips.
The crew philosophy is consistent: pull the 60-foot skis wherever possible to maximize ride quality. This commitment to using the best available technique on every segment, not just on critical sections, reflects the culture of excellence that drives award-winning results.
Material Transfer Vehicles for Production and Quality
Material transfer vehicles (MTVs) played a critical role on this project for three primary reasons: preventing truck impact on pavers, remixing the material for temperature and aggregate uniformity, and increasing production rates. The production benefit was significant. Using an MTV allowed the crew to place as much as 100 more tons per hour compared to direct truck-to-paver dumping.
MTVs were used on the top two lifts where mat quality matters most. By remixing the material, MTVs ensure consistent temperature throughout the mat and reduce segregation, both of which contribute to longer pavement life and better ride quality.
Roller Configuration for Target Density
Compaction is where pavement durability is won or lost. On this project, Cummins employed a combination of BOMAG and Dynapac rollers in a three-roller train: a breakdown roller for initial compaction, a pneumatic roller for intermediate density and surface sealing, and a finish roller for the final smooth surface. The team conducted quality control throughout using Troxler nuclear density gauges to verify that compaction targets were met on every lift.
Mix Design, Lift Placement, and Quality Control
The technical specifications of the asphalt mix and the layering strategy are as important as the equipment used to place it. On US-183/US-270, the mix design was developed in collaboration with the company central lab, and the lift structure was carefully planned to handle projected traffic volumes. Over 98,000 tons of asphalt were placed to widen and repair this stretch of roadway. For a deeper look at the machinery used in these operations, see Asphalt Equipment a Comprehensive Guide to Paving Compaction.
Lift Structure and Tonnage
The four-lift system used on this project demonstrates the importance of building pavement in layers that match the structural requirements of each level:
| Lift | Mix Type | Tons Placed | Purpose |
|---|---|---|---|
| Lift 1 (Base) | S364 | 65,200 | Structural foundation for the pavement section |
| Lift 2 | S376 | 18,087 | Intermediate binder course |
| Lift 3 (Surface) | S476 | 14,370 | Wearing course for ride quality and durability |
| Shoulder | Shoulder Mix | 7,000 | Edge support and drainage transition |
Cold Milling and Full-Depth Repairs on Existing Sections
Phase 3 of the project involved significant removal work on the existing lanes. Crews used a Wirtgen mill to cold mill the top 2 inches of old pavement and resize the shoulders from 10 feet down to 4 feet on the inside. This required removing 75,000 square yards of asphalt just to achieve the new shoulder configuration. Full-depth repairs were performed in several locations along the existing roadway where the pavement structure had deteriorated beyond what surface milling could address.
Working safely around heavy machinery and hot mix asphalt requires strict protocols. Every crew involved in milling, paving, and compaction must follow established safety procedures to prevent injuries and maintain productivity. Reviewing Asphalt Safety Comprehensive Guide to Hazard Management in operations helps ensure that quality and safety go hand in hand.
Measuring Success Beyond the Award
While the OAPA Full-Depth award recognizes the US-183/US-270 project specifically, Cummins also won the Rural Overlay award for US-412 in Woodward County and the Urban Overlay award for SH-3 in Blaine County during the same award cycle. The company was selected as runners-up in two additional categories. This level of recognition across multiple project types demonstrates that a culture of excellence produces consistent results regardless of project scale or location.
The key takeaway for paving contractors aiming to elevate their own operations is that excellence comes from the intersection of three factors: people who take ownership of their work, equipment that operators trust and maintain well, and processes that are followed consistently on every project. When these three elements align, award-quality pavement is the natural result.
The US-183/US-270 project shows that investing in the right equipment, listening to crew feedback, and phasing work intelligently produces roads that serve communities safely for decades. Contractors who build this culture into their daily operations do not just win awards. They build lasting relationships with owners, agencies, and the traveling public who depend on high-quality infrastructure every day.
