Phoenix, Arizona — Phoenix is trying to beat the heat by turning its black asphalt streets gray. A special sealant reflects rather than absorbs the hot desert sun.
Phoenix Mayor Kate Gallego says the so-called cool pavement is 10 to 12 degrees cooler to touch than traditional asphalt. About 73 miles of the city's streets are now covered in the sealant.
"Our residents say they can feel the difference," Gallego told CBS News.
