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 team worked 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.
