Evaporative cooling on pavement has recently been developed in order to reduce the heat in summer in outdoor spaces. In this pavement system all materials have capillary ability. Stored rain water is used and no motive power is required to supply water to the system. Appropriate bricks and textiles which have capillary ability are chosen. These materials suck up and spread water efficiently and wet the whole surface. The results of measurements in summer show that the wet surface is 10 degrees cooler than the dry surface, and more than 25 degrees cooler than asphalt surface. Water supply through the materials continues for several days. Sensible and latent heat fluxes from wet pavement at noon in summer are about 70W/m^2 and about 430 W/m2, respectively. It is estimated that thermal diffusion coefficient of both wet bricks and wet sand are 0.00126m^2/h and surface wet ratio is 0.70.
