This project will improve approximately 3,700 linear feet of roadway. The Mill and Overlay process involves grinding off the top layer of existing asphalt pavement by means of a large milling machine and replacing this layer with at least two layers of a new Hot Mix Asphalt (HMA) riding surface. Typical depth of milling is between 1 inch and 2 inches, depending on the condition of the existing riding surface, depth of available curb reveal and depth of existing asphalt pavement. A leveling course may applied prior to the final riding surface to resolve rutting, depressions or other roadway profile issues and ensure proper drainage. Castings are raised to grade.
The work involved in this treatment goes beyond the pavement. Drains are replaced if needed before paving. The curbs are re-laid or replaced if they are in poor condition. Sidewalks are rebuilt if they are in poor condition. Pedestrian improvements such as ADA (Americans with Disability Act) ramps and crosswalks are installed. Street signs are replaced as needed. Finally, the landscaped areas are loamed and seeded.
During the 2018 construction season, the Department has scheduled the following roadways for Roadway Rehabilitation:
This work is scheduled to begin in Spring / Summer 2018.
