SMALL PROJECT OF THE YEAR SMALL PROJECT OF THE YEAR STAKER PARSON MATERIALS & CONSTRUCTION — MAIN STREET - CENTER STREET NORTH SALT LAKE JONES & DEMILLE ENGINEERING — SR-153 NOMINEE NOMINEE This project involved removing and replacing the existing curb and gutter, sidewalk, waterways, and pedestrian access ramps. The project team also removed the entire existing roadway asphalt, cement treated the existing road base, graded and compacted the cement-treated road base, and installed 4.5-inches of new roadway asphalt. This project used a cement slurry treated base. Normally, work is done in the existing subgrade materials, which then have either an existing or new base installed on top of them. Instead, the team removed the asphalt surface and treated the existing base. The teamworked with UDOT and the city to determine the best method for doing this work and the correct cement ratio for the expected product. The project team’s challenges included traffic access and the roadway’s slope. Many residents live on this street, and the team had to keep open access to their properties. Also, the west side of the roadway had a very steep slope. The slurry would have run off the roadway into the curb if the project team had used a standard cement slurry treatment. They had to figure out how to place the slurry where it could be mixed in the existing base and kept out of the gutters. They used good communication and planning to accomplish their goals. This project was bid late in the year, so another was time. Thanks to teamwork between the owner and Staker Parson Materials & Construction, work began at the beginning of September and finished before November. 3 This project included a lane level and overlay on the cracked surface of SR-153 between MP 3.04 and MP 19.2. The route runs along Beaver Canyon and the Beaver River. Highquality work was required because the hot plant was an hour away, and has tight curves, varied widths, steep grades, and multiple river crossings. Due to the narrow 25-foot average road width, this project also included one-foot shoulder widening on shoulders where possible. The existing roadway conditions, harsh winter conditions, and restricted sunlight during the winter season made it important to place material that would last. UDOT elected to install a fiber-reinforced asphalt overlay section that will add longevity to the pavement life and slow down the reflective cracking, thus preserving the road’s life and minimizing maintenance along this section of highway. The narrow roadway width did not leave much room for the paving crew to work and allow for traffic to pass, and highway elevations range from 6,000 feet to over 10,000 feet. As a result, traffic control and advanced notice of the anticipated work zone were critical for the safe passage of large trucks and other vehicles. The project team focused on adequate signage and added additional signage to alert oncoming drivers. The project team placed approximately 3,680 tons of HMA 3/8-inch material as a lane leveling course over the existing HMA. After placing the lane level, they placed a 1.5-inch overlay with 11,797.91 tons of fiber-reinforced HMA. The contractor received more than 82% of the possible smoothness bonus without a single project grind. The completed product will be an example of quality for years to come. 3 38
