The main purpose of this rehabilitation project was to correct the hazards on the existing roadway caused by subgrade cracking and movement due to the high clay content underneath the roadway. This clay, over time, causes the road to heave and move, causing many surface deficiencies that must be corrected, mainly affecting the smoothness of the road surface. Profile Milling was identified by UDOT designers as a solution in the design process. Various depths of profile milling from 0.25” in some locations to 2” maximum depth removal of material in other more prominent rough areas were utilized and completed. The material removed from the existing surface of the roadway was conveyed and placed on the shoulders of the roadway utilizing existing materials to widen and stabilize the narrow shoulders of the roadway, providing UDOT with a road with more width, thus increasing the safety for the traveling public in the area. Once the profile milling was completed, warm mix SMA was placed in a single 1.5” lift utilizing automatic leveling controls on the paver to establish the final smooth and improved roadway surface. Notably, partnering between UDOT engineers and the Burdick Materials team allowed the project team to successfully complete the final paving with the warm mix SMA on this project meeting all UDOT paving requirements late in the construction season on Nov. 3, 2023.
