This nominated project placed approximately 8,245 tons of HMA 3/8 Inch material in the amount of $1,014,100.56 as a lane leveling course over the existing HMA. Once the lane level was placed a 1 ½ inch overlay with 16,810 tons of SMA ½ Inch was placed in the amount of $2,067,680.43.
This project included a mill and fill of SMA on Main Street in Escalante from MP 58.86 to MP 59.85. From MP 59.85 to MP 70 an HMA lane level SMA overlay was placed. Due to the winding and narrow nature of SR-12, the Utah Highway Patrol limited the route to bring in a hot plant. It was required to bring in the hot plant from the west side of SR-12 and not over the Boulder Mountain. Once the hot plant was set up, it was located on the south side of the Escalante River. This caused potential problems and often made the road to and from the hot plant impassible due to flash flooding upstream of the project. It was critical that the project team worked with the county, school district, Escalante Town, to ensure that the construction of the grade of these areas was completed prior to the anticipated paving schedule. WW Clyde’s partnering efforts were truly exceptional as they exceeded the project expectations in paving and in the quality of their product.
When it comes to project quality, the quality of the product and ride was remarkable. For the SMA, they were able to achieve $2.60 per ton as an incentive. For this roadway, the contractor was able to pave the project in a manner to achieve over 75% of the possible smoothness bonus. Typically, it is estimated that for budgeting purposes, the contractor could achieve 70% of the possible smoothness bonus. Add into this project sharp compounding curves, intersection tie-ins, trucking issues, it puts into perspective the top-quality job that was completed.
One additional aspect that was mentioned earlier was the intersection tie-ins. This project included the construction of 35 pedestrian access ramps. As part of the construction of these ramps, paving in and out of them are critical to make sure ADA requirements are met for clear space and crosswalk running and transverse slopes.
