BACKGROUND The City has two annual projects designed to maintain roadway infrastructure: the Annual Street Resurfacing and Preventative Maintenance Project and the Annual Slurry Seal Project. The first project resurfaces various roadways by overlaying the existing pavement with a new layer of asphalt concrete, while the other project slurry seals a different set of roadways. The resurfacing project is considered a street reconstruction project, while the slurry project is a preventative maintenance project. Together, these projects are designed to maintain the city's roadway pavement condition. Slurry seal is placed on streets that are in a good condition to seal the street before deterioration of the surface occurs, which would allow water to penetrate the roadbed and lead to premature failure of the roadway. Slurry seal treatments are expected to last six to eight years, depending on the amount of traffic on the street. Slurry seal costs approximately one-fifth of the cost to overlay a street with a new layer of asphalt concrete and is a cost-effective approach to extend the useful life of the pavement. Slurry seal is a petroleum-based emulsion product that consists of a mixture of water, asphalt emulsion, aggregate, polymer, and chemical additives. It is blended on-site in a large truck and then applied evenly across the entire roadway surface of an asphalt street. The slurry seal is typically 1/4 to 3/8 of an inch thick. The aggregate is a mixture of fine sand and black volcanic rock that increases the roadway friction and maintains a black surface several years after placement. The slurry seal process typically requires streets to be temporally closed to traffic between 8 a.m. and 5 p.m. The slurry sealed surface will be tender and subject to surface blemishes typically for a few weeks following the placement of the slurry, depending heavily on the weather. Residents are provided information on how to reduce the surface blemishes by not making sharp turns or turning the wheels while the car is not moving. DISCUSSION The project consists of applying slurry seal on 920,000 square feet of pavement on 17 street segments. See Attachment 2 for a map of street locations.
