Irvine coated a half-mile stretch of two connected streets with cool pavement; August and September measurements found the treated asphalt ran about 7-10°F cooler

Cities worldwide are turning to cool pavement technologies to tackle urban heat. In Irvine, California, treated roads have experienced a remarkable temperature drop of 7 to 10 degrees Fahrenheit. Meanwhile, Phoenix has successfully covered over 200 miles of road since 2020, while San Antonio’s $1 million investment exemplifies the growing trend. This innovative coating reduces the heat retention of asphalt, contributing to efforts against increasing temperatures.
