The results of a year-long pilot project that tested the efficiency of cool pavement, a water-based asphalt treatment that reflects heat instead of retaining it, were announced last week by the City of Phoenix Street and Transportation Department.
Jennifer Vanos, co-lead of the project and assistant professor at the Arizona State University School of Sustainability, reported that on average, cool pavement ranged from 10.5 to 12 degrees cooler than regular asphalt during afternoon hours. The air temperature surrounding the pavement also decreased by 0.5 degree at night and 0.3 degree during the day. While these numbers seem low, air from parts of the neighborhoods that were not involved with the pilot project could have mixed in with the parts that were involved, Vanos said.
