Dark pavement can contribute to these higher temperatures, but a new asphalt treatment could reportedly cut street temperatures by as many as 6.6 degrees Celsius (12 degrees Fahrenheit) after just one coat.

Black asphalt absorbs between 80 and 95 of sunlight, but the “cool pavement” treatment marketed by the California-based sealcoating firm GuardTop reflects it. This could have a big impact on street temperatures and make life more comfortable for people in urban environments.

After successful testing the treatment in parking lots, Los Angeles is ready to be the first major city to put it through its paces on a public road. Officials will monitor how residents react to the new pavement, as well as how long it takes for traffic conditions to soil the gray coloration of the coating.
As Alan Barreca, an environmental science professor at the University of California, Los Angeles, told AFP, “Lower temperatures — due to the pavement — mean less reliance on air conditioning. So, that means less greenhouse gases.”

Of course we know about the Urban Heat Island effect.

Yes. It is just the adjustments that are problematic.

Of course we know about the Urban Heat Island effect.

If the treatment works it should make cities more comfortable, more so when EVs are the majority of vehicles in the streets.

Thanks for the info, Baron!
