Each year, at the annual dinner, UAPA has the opportunity to celebrate excellence in infrastructure and the dedication required to build lasting, quality pavement projects.

The recognition of these projects goes above and beyond standard specifications, setting a new benchmark for quality, durability, and safety.

UAPA thanks all those who submitted projects for consideration, the judges who had the difficult job of narrowing down the winners, and, of course, the hundreds of dedicated crew members who worked tirelessly to achieve the outstanding results demonstrated in every project nominated, not just those that won this year.

The UDOT I-15 Arizona State Line Pavement Preservation Project showcased a strategic approach to extending pavement life along a critical, high-volume corridor. Spanning 19.6 miles, the project used microsurfacing to fill ruts, improve ride quality, enhance skid resistance, and extend pavement life by an estimated five years.

Nighttime construction minimized traffic disruptions while targeted asphalt patching and surface smoothing improved ride uniformity and durability. Pavement markings were also upgraded to current MUTCD standards to improve safety and visibility.

The project highlights strong collaboration between UDOT, Intermountain Slurry Seal, and the design team to deliver a cost-effective preservation strategy that protects infrastructure investments and improves long-term performance.

Safety remained a top priority throughout construction. Intermountain Slurry Seal implemented daily safety briefings, enhanced nighttime lighting, and carefully planned traffic control measures, with additional support from the Utah Highway Patrol.
