Photo taken on Sept. 3, 2019 shows the 200-metre stretch of blue road paved with the so-called 'cool pavement'. The 'cool pavement' is set with a protective material to reduce the damage from contact with vehicles and to extend its life. The 'cool pavement', reflecting about 50 percent of sunlight, consists of four layers of a primary material, followed by three layers of materials that reduce heat absorbed by solar radiation.
