Surface temperatures at sunrise averaged 2.4 degrees Fahrenheit lower. Cool pavement had an average surface temperature 10.5 to 12 degrees Fahrenheit lower than traditional asphalt at noon and during the afternoon hours.Cool pavement revealed lower surface temperatures at all times of the day versus traditional asphalt.Findings from year one of the study include: Because of this higher reflection, the coating has the potential to offset rising nighttime temperatures in the region.
Cool pavement coating reflects a higher portion of the sunlight that hits it, hence absorbing less heat. Year one of the study done by scientists at ASU's Global Institute of Sustainability and Innovation, Healthy Urban Environments, and the Urban Climate Research Center revealed that reflective pavement surface temperatures are considerably lower than traditional roadway pavement. The program and analysis of the cool pavement process is being conducted in partnership with Arizona State University (ASU). The Phoenix Street Transportation Department and Office of Sustainability announced during a virtual presentation and panel discussion on Septemthe results of the first year of its Cool Pavement Pilot Program.
