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.
