LARGE PROJECT OF THE YEAR NOMINEE PROJECT OVERVIEW • U.S.-191 — Profile mill, scrub seal, and 2” spray paver applied SMA. • SR-44 — Scrub seal and 1.5” spray paver applied SMA. WHAT MAKES THE PROJECT UNIQUE The roadway was rough with considerable cracking and the asphalt was generally thin (1.5” to 5”). Heavy alligator cracking was present in many locations on SR-44 and U.S.-191. Due to budget constraints, the asphalt could not be removed and replaced with a 4.5” overlay. On SR-44, after repairing the worst soft spots, a scrub seal was used to seal the cracks followed by a 1.5” spray paver applied SMA overlay. On U.S.-191, natural springs coming up through the middle of the road in two locations required the installation of French drains. The contractors, consultants and the owner worked well together and did a spectacular job dealing with all of the project challenges. Using scrub seals as underseals and using spray pavers for thicker pavement lifts is relatively new to Utah, but the contractor performed well and provided a great finished product. Projects and studies from the Midwest have shown that underseals and spray paver-applied overlays reduce cracking, improve impermeability, have longer than typical service life and lower life cycle costs. This project is anticipated to last longer and perform better than a standard mill and overlay for less overall life cycle cost. SAFETY RECORD The project had zero recordable incidents in just over 15,500 man-hours worked. Burdick Materials was able to complete this project with a 95%+ average on our UDOT safety inspections. To help mitigate the risk of miscommunication (or lack thereof), a new headset radio communication system was implemented to achieve this critical communication from ground level up. Not only was the communication between the crew faster and more constant, but the headsets also acted as additional hearing protection for the crew as well, eliminating another hazard that is always present with constant exposure to loud paving equipment. In addition to this risk, their biggest concern involved the crews working in or near traffic on Utah highways, especially through these high recreation areas. Burdick Materials worked closely with their traffic control subcontractor, First Source Enterprises, and its crews and did a great job of mitigating the hazards to the traveling public and the project workforce through the various and ever-changing work zones for the duration of the project. PROJECT QUALITY The Asphalt Pavement Profile Grinding met all requirements for the specifications and provided for a smooth base to begin the other methods of pavement preservation. The scrub seal met all the application rates for the placement of the emulsion and the aggregate surface material. The SMA placement also exceeded the requirements for the mix design, earning the contractor bonuses for this item of work. The craftsmanship of the placement of the spray paving applied to the SMA was exceptional. The contractor only had 12 grinds to correct smoothness for almost 14 miles on SR-44, with the majority of these being on joints. UDOT maintenance personnel expressed their appreciation for the exceptional project provided by the contractor and consultant RE, and noted that the project progressed very smoothly considering the issues encountered, the area, and recreational traffic.
