Mill and Overlay
Streets receiving a mill and overlay treatment will have the surface of the road milled for the entire width of the street. A new asphalt surface will be placed on the roadway approximately 10 days after the milling is complete. Access will be provided by flaggers working in the construction zone.
Streets receiving a mill and overlay will also receive concrete rehabilitation before the pavement treatment. This effort repairs broken curbs, gutters, sidewalks and other concrete structures that if left unrepaired will shorten life of the major rehabilitation investment. As part of this work, curb ramps will be repaired and brought to current Americans with Disabilities Act (ADA) standards.
Street segments receiving this treatment will receive a new wearing surface on top of the existing asphalt. The street is closed for approximately 2 hours for the application of the slurry seal as well time for the new surface to dry. This process seals the cracks in the road as well as protects the existing asphalt surface.
Street receiving a slurry seal will also receive a crack seal treatment. Crack seal is the process of cleaning out existing cracks in the road and placing a hot asphalt rubber to protect moisture from entering the crack. This process is performed with a mobile operation in which a flagger will help assist providing access through the construction zone.
