The company that developed the "cool pavement" material is Emerald Cities, which offered to do the installation at the school and finished the project a few weeks ago.
The material is made up of light-colored pigments (green is not the only color) and a nano-engineered concrete that is stronger than normal concrete. That allows just a thin coating to be sprayed on, rather than a two-inch coating applied with heavy equipment.
