Heat-reducing pavement

[longknife]

City administration of the capital of Qatar, Doha, began painting city roads in blue, as part of a pilot project to combat the effects of extreme heat. Qatar is scheduled to host the 2022 World Cup.

“The temperature of dark asphalt is 20 degrees Celsius higher than the actual temperature, because black attracts and radiates heat,” Doha city engineer said, reports to Ar Raya.

According to him, painting asphalt will help reduce its temperature by 15-20 degrees, as well as increase the service life of the coating.

Currently, roads are painted only on one of the central streets of the city, where the temperature can rise to 50 degrees Celsius (122 degrees Fahrenheit) due to the lack of trees.

I wonder if it will catch on elsewhere.

Duh, a concrete road is off white and reflects even more heat, and as is obvious a blue road is retarded like the morons who painted it

Qatar must be full of third grade engineers

PS. Painting the pavement has a zero effect on the air temp of 110 degrees in the shade unless you live on the pavement in the inch above that pavement, where the air temp will still be increased, so this has no purpose except to demonstrate the lack of intellect of morons
