PAVEMENT STRUCTURE FOR REDUCING HEAT ISLAND

摘要

A pavement structure for reducing heat island is provided to cool a road effectively without spreading water on the road surface by supplying water to a surface course through a water supply layer when the surface course is dry. A pavement structure for reducing heat island comprises a surface course(100), a water supply layer(200), and a water supply unit(300). The surface course is formed of porous asphalt. The waster supply layer is formed under the surface course, and supplies water the surface course. The water supply layer is made of material which is easy for water to infiltrate and move around. The surface course run short of water, a lot of pores are formed in the surface course. At that time, the water in the water supply layer is moved into the surface course through a capillary phenomenon.
