The Public Works Research Institute in Japan has experimented with paints with such pigments applied to conventional asphalt surfaces. They made a road that reflects 86% of infrared light, which helps keep the surface cool, yet reflects just 23% of visible light, to keep down glare.
There are other benefifs too. Computer simulations of Los Angeles show that resurfacing about two-thirds ofroads and rooftop with reflective surfaces, as well as planting more trees, could cool the city by 2-3 degree C.That will reduce LA smog as much as total ban on cars and lorries, and cooler roofs could also save a fortune in electricity bills.
Go On, Paint Your Town White.
