This project included an overlay of 1” of Bonded Wearing Course — Type B for 3.5 miles of southbound I-15 through Davis County for a total of 185,000 square yards. The equipment used for this work included a Bearcat Spray Paver, Roadtec Shuttle Buggy, and 84-inch rollers. The project also included 137 cubic yards of soft spot repair using ½-inch PG64-34 HMA, a 3/8-inch HMA level course and pre-profile grinding for smoothness. Other items of work on the project included grooving for pavement marking tape with thermos plastic messaging, (Roadsafe), pavement shouldering with untreated base course, (Rowser Construction), and various tree trimming and removal activities, (Diamond Tree Experts).

This project is unique in the fact that the allowable traffic control window for closing multiple lanes was from 10 pm to 5 am, essentially restricting available paving hours to a total of five when one hour for traffic control setup and one hour for takedown and temporary striping was factored in. The project team utilized weekends, and specifically the Saturday night into Sunday day shift, for a longer pacing window which included two full passes, or seven miles of paving in one long shift. This project was completed a total of 15 days ahead of schedule and achieved full early completion incentive for time.

This project achieved a perfect safety record with zero incidents or recordables in 1,100 manhours worked. This project was a challenge to get started as there was no Highway Patrol support available to start the project due to other concurrent UDOT projects. Instead, with the help of the department, we utilized UDOT incident management personnel to help set up and take down traffic control and keep the crew safe. This greatly reduced the speed of traffic through the work zone and allowed the work to progress through one of the busiest sections of I-15 in the state. The plant achieved excellent mix quality, earning $14,000 in AC and graduation incentives on six separate lots. This project smoothness incentive totaled $102,000 on approximately 21 lane miles. This project was a success for Geneva Rock, Consor Engineering, UDOT Region 1 and the traveling public.
