36 PROJECT OVERVIEW NARRATIVE THE UAPA PAVEMENT PRESERVATION AWARD Project Description The Pavement Preservation Award for 2019 has been given to the Tooele County 2018 RAP Chip Seal project on the Aragonite, Clive, andGrassyMoun- tain Roads in Tooele County, Utah. This project began in August 2017 and was completed in June 2018. When UDOT made their annual visit to Tooele County in 2017, a pavement preservation project on I-80 between mile markers 20-30 was mentioned. Rod Thompson followed up with Charles Mason-Hill, a UDOT Region 2 preconstruction engineer, who gave him contact information for Geneva Rock Products Inc. project manager Dexter Tan. They met, and during that meeting they agreed to purchase some reclaimed asphalt pavement from this project and stockpile it. The plan was to makeaggregate for chipsealing fromthe reclaimed asphalt pavement.They knew the aggregate for the chip seal would provide a new skid-resistant wearing surface, stop raveling, seal minor cracks and slow further deterioration of the road surface. Drivers used Tooele County Road Department trucks and trailers to haul themilled asphalt in order to help offset the cost of the RAPmaterial. The county rented an Astec model 2612 V Pro Sizer crushing/screening plant. Four screens were purchased to fractionate and crush theRAP into5/16-inchchipsmeeting the LACounty specifications for chip sealing. GoodfellowCrushinghauled the crusher out to the centrally located stockpile location and set it up. Some of Tooele’s county crew members were trained on the operation of the crusher, and they processed the material in January and early February of 2018. The locations of potholes on the road were marked with spray paint. Based on a square-foot price, Ridge Rock Construction was contracted to do the full-depth patching in the early spring of 2018. The 21-mile chip seal operation began in June of 2018. • The emulsion supplier was Western Emulsion. • The emulsion trucking and distribut- ing was completed by R&M trucking. • The Tooele County Road crew placed temporary pavement markers, took care of traffic control and sweep- ing. They also operated the chip spreader and loaded, hauled and compacted the chips. • Paint striping was completed by MountainWest Striping. The project was unique for several reasons: • It was the first time aggregate for chip sealing was made from reclaimed asphalt pavement in Utah. The RAP chips performedbetter thannewvirgin aggregate chips because they were pre-coatedwith liquid asphalt residue. • Project leaders saved time andmoney by using the available recycled mate- rial rather than hauling new crushed chips to this remote location. • Those working on the project faced a challenge because the only specifica- tions for the emulsion and aggregate gradations were from out of state. The project maintained safety by imple- menting the following measures: • A certified traffic control supervisor created the traffic control plan. Key project teammembers were as follows: • Rod Thompson of the Tooele County Road Department • Tim Beil of PEPG Consulting • Construction Material Testing • Dexter Tan and Tevita Tafoa of Geneva Rock Products • Cody Thorn of ConstructionMaterial Recycling • Mark Hanson of Goodfellow Crushing • Jared Wright and Doug Olsen of Western Emulsions • Troy Jacketta of R&MTrucking • Chris Potter and Charles Mason-Hill of the Utah Department of Transportation • Wayne Anderson of Ridge Rock Construction
