The project was completed under the minimum of 67 days with a total of 37 working days. WHAT MAKES THE PROJECT UNIQUE This project was unique in its location, half in a rapidly developing Heber City and the other half up Daniels Canyon with its narrow twists and turns and frequent wildlife crossings. Traffic control had to be adaptable to the specific scope of work and location in order to operate safely. The project team coordinated with three external developers whose projects required lane widening and paint line changes. Our team successfully surveyed the changes before the micro surfacing and seamlessly painted the new lines after the micro surfacing covered the old ones. In addition to dealing with a variety of traffic, we also faced challenges due to lane closure restrictions. Daytime work, which provided optimal temperatures for micro surfacing, was limited to Monday through Thursday, resulting in a four-shift week. However, by opting for night shifts, we could have lane closures from Sunday night through Friday morning. This choice allowed us to work more shifts and ensured crew safety with less traffic, but the cooler temperatures, often in the 50s, were less ideal for micro surfacing and took longer to set up. A sinusoidal rumble strip specification was used instead of a UDOT standard rumble strip due to the location. This design reduces the noise outside the vehicle caused by driving over the strips while maintaining the noise inside the vehicle. It was an ideal choice for the residential area, especially with semi-trucks hauling throughout the night. UDOT standard rumble strips, per STD DWG PV 6B, are 5” long and 6” wide for undivided highways with a 7” gap, creating a 12” cycle. Sinusoidal rumble strips, per the detail below, are 14” wide and are more wave shaped with zero gaps between cuts. SAFETY RECORD • The U.S.-40 project was originally designed to take place during the day, but after concerns with the traffic arose, UDOT approved a change to conduct construction activities at night. In addition to changing to a night shift schedule, pilot car operations were used for the majority of work to improve the safety of our crews and subcontractors. • There were zero traveling public accidents. • Intermountain Slurry Seal worked over 2,000 man-hours with zero injuries.
