Abstract
The recent abnormal climate and extreme weather events have frequently given unexpected casualties and damages. In particular, in cases accompanying with heavy rainfall or extremely hot weather in a short period of time, there increases possibility leading financial damage by flooding, heat island phenomenon etc.. One of the main factors that are caused these problems is impermeable area including asphalt and concrete pavement which is increased by urbanization. So, it is interested in porous pavement to solve the environmental problems in Korea. In this study, a block pavement system for sidewalk to control surface temperature of pavement and rainwater runoff was developed. The block pavement system is composed of permeable or water-retentive block and rainwater storage which can harvest and supply rainwater. Surface temperature of permeable block pavement is reduced about 10°C compare with it of impermeable block pavement. Also, rainwater runoff was not happened during the period of rainfall.
