Phoenix Tests Reflective Coating to Combat Asphalt Heat

Phoenix is experimenting with a novel approach to mitigate the intense heat generated by black asphalt, a significant contributor to urban heat islands. The city has applied a reflective coating to sections of its roads, aiming to reduce surface temperatures.

Initial observations indicate a notable decrease in surface heat, with temperatures falling by as much as 12°F at noon on coated areas compared to untreated asphalt. This initiative is part of broader efforts to address the environmental challenges posed by extreme heat in urban environments, potentially offering a scalable solution for other cities facing similar issues.
