The City of Phoenix is installing its 100th mile of Cool Pavement this month. The special street coating is being applied to neighborhood streets in Laveen on Tuesday. The specific area getting the temperature-lowering coating is the area of Lower Buckeye Road and Durango Street between 83rd and 79th avenues. "The seal coat material is a water-based, non-toxic, recyclable product. It is not paint. It is an emulsion made of water, asphalt, polymers and filler minerals that bond to asphalt," according to the city.
