Phoenix’s Reflective Pavement Reduces Road Heat but Increases Pedestrian Warmth

Phoenix’s CoolSeal coating lowers asphalt surface temperatures by about 10–12°F, but it reflects heat upward, raising mean radiant temperature for pedestrians near treated roads by roughly 7°F at midday; planners should deploy the technology in low-foot-traffic, unshaded areas to gain nighttime cooling without worsening daytime pedestrian comfort.
