Many cities around the world continue to evolve creating larger urban centers, with increased population and greater built infrastructure. This infrastructure growth and the frequent occurrence of higher temperatures than usual are raising additional concerns regarding the Urban Heat Island (UHI) effect. This presentation will focus on the pavements role in contributing to UHI, evaluation techniques, driving factors, physical and thermal properties of materials, and modified pavement materials opportunities to assist in mitigation. Examples from what we have learned from recent studies will be provided to demonstrate how the UHI can be better lessened.
