Composition and types of cool pavements

Drawbacks
A drawback of cool pavements is glare, which impacts visibility for drivers. Another is durability as some cool pavements can degrade faster than traditional pavements due to the coating used being not as durable as asphalt or concrete. There is also a higher initial cost in building cool pavements compared to traditional pavements which needs to be taken into consideration before widespread adoption. A potential issue can be higher energy usage by nearby buildings, however this would depend on the material the buildings are made of. As glass buildings themselves reflect heat whilst concrete buildings absorb heat. Aesthetic considerations can be taken into account as cool pavements would deviate from the traditional look of pavements found in urban environments.

Cities
Los Angeles, Phoenix, and Tokyo have experimented with cool pavements. Los Angeles for example has laid out 181 lane-miles of solar-reflective coating.
