SCOPE
The 2019 Residential and Arterial Pavement Improvement, I-159/I-139 is designed to provide scheduled maintenance and preservation treatment to existing asphalt paved roadways. In areas where ponding occurs, some curb, gutter, sidewalk and tree removal/replacements will be performed prior to pavement repairs. Areas requiring additional pavement improvement will include dig-outs or cold milling and overlay. Cold milling and overlay requires the removal of the top layer (typically 2 inches) of a street and replacing it with a new layer of bituminous pavement. Slurry seal is a liquid mixture of asphalt emulsion and sand that is thinly applied to the surface of asphalt roadways. Slurry seal is a temperature sensitive material and is best applied during warm weather. It is one of the most versatile and cost-effective methods of maintaining and protecting roadways. Both the cold milling and overlay and slurry seal application process requires full closures of streets for approximately 9 to 10 hours to allow for preparation of work (e.g. street sweeping and setting up traffic control), cold milling and overlay or slurry seal application, material curing, and clean-up. No vehicles will be allowed on the street until the work is complete. CityClerk@TorranceCA.gov publicworkinfo@torranceca.gov
