With temperatures rising across the globe, cities are paying more and more attention to urban heat islands and how they are making our cities less livable. Various organizations such as NASA, the EPA, and AA have been studying the urban heat island effect as well as ways to mitigate the issue. One solution that has been identified is the use of reflective surfaces in order to lower temperatures within the built environment. Cool pavement is a solution consisting of a reflective coating applied to an asphalt surface. Asphalt typically absorbs over 90 percent of heat from the sun, whereas cool pavement can reflect over 40 percent of incoming heat. Various cities have implemented cool pavement programs with high levels of success. Ryan Stevens and the City of Phoenix, Arizona, have been using cool pavement techlogy since 2020. The city has released various studies and reports highlighting the benefits they are seeing. This presentation will highlight the importance of heat island mitigation and the benefits cities are seeing from using cool pavement. After this session, participants will be able to:
• Identify what an urban heat island is and what can be done to improve the growing problem.
• Describe how a cool pavement can be easily implemented into an existing asphalt maintenance plan.
• Identify how cool pavement can improve asphalt infrastructure and save money.
