Background:
Surface sealing is a street surface treatment designed to extend the life of existing pavements at about one-third to one-fourth the cost of milling and overlaying a pavement. Timely application is necessary to extend the life of existing pavements. This process is similar in concept to painting a house instead of waiting to replace the siding.
Surface sealing with Micro Surface is a specialized process, so there are very few contractors that specialize in micro surfacing and slurry seal work. Surface sealing uses a mixture of fine aggregate, polymer-modified asphalt oils, Portland cement, and mineral fillers. This process seals the entire roadway with a 1/4 inch-thick layer of the oil-aggregate mixture. The first step in the sealing process is filling surface cracks and voids to make them weather tight, similar to caulking seams on a house to prevent water infiltration. The surface seal mixture is then placed over the entire street to provide a water resistant surface that mitigates aging of the pavement cause by UV rays from the sun.
Timeline:
Start: June 2020
