Cool Pavement Pilot Program
The City of Phoenix Street Transportation Department partnered with the Rob and Melani Walton Sustainability Solutions Service at Arizona State University and researchers from various ASU schools and research centers to evaluate the effectiveness, performance and community perception of a new pavement coating applied to mitigate urban heat effect. The data collection and analysis occurred across multiple neighborhoods and at varying times across days and/or months over the course of one year (July 15, 2020–July 14, 2021), allowing the team to study the impacts of the surface treatment under various weather conditions. Numerous types of platforms and sensors were used to collect data, with further analysis completed in ASU laboratories. The research produced a number of key findings, including the following:
