Two new coatings added to Berkeley Lab's Cool Pavement Showcase

On Saturday, March 16, the Heat Island Group added two new cool pavement coatings to the Bevatron Lot at Berkeley Lab. The new additions feature Western Colloid Armor Top asphalt-based coatings in two colors - Stealth Gray (near in image at right) and California Tan (far). The coatings are tinted light colors using titanium dioxide and recycled materials to produce a surface with an initial solar reflectance above 20%, higher than the 5-10% of the dark asphalt parking lot surface underneath.
