The City of Phoenix Street Transportation Department partnered with the Urban Climate Research Center and the Rob and Melani Walton Sustainability Solutions Service at Arizona State University, and with researchers from various ASU schools and centers, to evaluate the effectiveness, performance and community perception of a new pavement coating designed to mitigate urban heat. Data collection and analysis for the cool pavement pilot project occurred across multiple neighborhoods from July 15, 2020 to July 14, 2021. Data gathered at varying times across days and months from each site allowed the research team to study the impacts of the pavement coating under various weather conditions. Numerous platforms and sensors were used to collect this data, with further analysis completed in ASU laboratories.

The second phase of the project explored a new iteration of the cool pavement coating, which was applied in seven neighborhoods between May 31 and June 6, 2022. The results of this study were shared in October of 2024.
