Sustainable Use of Cool Pavement and Reclaimed Asphalt in the City of Phoenix
In 2020, The City of Phoenix began work on two projects to improve sustainability and livability: The Cool Pavement Pilot Program (CPPP) and Reclaimed Asphalt Pavement (RAP) trials.
Faced with long-term projections of rising urban temperatures and an increased frequency of dangerous heat waves, jurisdictions are seeking ways to reduce pavement temperatures to improve sustainability and resilience. The City initiated a pilot program to evaluate a colored pavement coating, building off previous work in Los Angeles. The City enlisted help from Arizona State University researchers and scientists for a comprehensive evaluation of the CPPP. The project includes thirty-six miles of pavement across the City. After extensive public outreach, installation occurred between June and October 2020. The CPPP resulted in unprecedented media interest, positioning Phoenix in the spotlight for technology and innovation both locally and nationally. Cool Pavement may measurably improve comfort and livability in the City.
In 2019, approximately twenty-one percent of all asphalt pavement in the United States included Reclaimed Asphalt Pavement (RAP). The City’s stance on RAP recently changed because of improved methodologies for ascertaining the quality and performance of RAP and is exploring its use. The City has partnered with Arizona State University to study and test the feasibility of using RAP. Trial projects have been constructed with RAP in slurry seals, microsurfacing and overlays. The City also developed two sites to create RAP from asphalt millings generated in day-to-day maintenance operations.
