The National Asphalt Pavement Association (NAPA) will honor Hales Sand & Gravel, a CRH company, during its annual meeting in January, as the winner of the Quality in Construction (QIC) Award for three projects it completed this year. The following projects will be recognized: SR 137 in Sanpete County, SR 28 and US 89 in Sevier and Sanpete counties, and SR 62 in Sevier and Piute counties.
The SR 137 Project, in Sanpete County, was an overlay that took place in Gunnison, Utah. The project added more width to the highway, while greatly improving the smoothness of the stretch of road. An additional turning lane and acceleration lane were added near the Mayfield Estates Subdivision. The team utilized their resources to complete this project well ahead of schedule.
SR 28 and US 89 in Sevier and Sanpete counties consisted of building a new acceleration/deceleration lane and supplying SMA while recycling existing asphalt (Hot-In-Place asphalt). Hot-In-Place recycle is a process that heats up the top 1 ½ in. of existing asphalt, scarifies the heated asphalt, then adds an asphalt emulsion. After the Hot-In-Place asphalt process is complete, the asphalt is re-laid, then 1-½-in. SMA is added on top of the recycled (Hot-In-Place) asphalt. All of this was completed with a single train.
The train consisted of three preheaters and a heater/mixing unit/paver, as the final piece. The project was completed using 7,300 tons of ½-in. SuperPave and 24,000 tons of SMA. This project is unique because it is the first project in the state of Utah that SMA was used in conjunction with Hot-In-Place recycled asphalt.
The SR 62 Project, located in Sevier and Piute counties, was a 22-mile overlay project that turned out to be a great success for both the Utah Department of Transportation (UDOT) and Hales Sand & Gravel. The additional lane width, along with the percentage of smoothness gained in this project, was outstanding.
Before construction, the average width of the road was 24-ft. wide, with 10-ft.-wide travel lanes. After construction, the average width was 27-ft. wide, with 11-ft.-wide travel lanes. These improvements, not only improved the quality and smoothness of the road but increased the safety of the road for the traveling public.
“The crews did an excellent job of adding additional width to the roadways along with improving the smoothness. The last construction on this section of SR 62 was in 1964, “Jeff Collard, general manager, Hales Sand & Gravel, said. “Our crews took the challenges and met them head-on, producing a quality product and constructing quality projects. I am extremely proud of how well our crews overcame the challenges and how well they performed on these projects.”
