In recent years, the heat island phenomenon is paid attention. The various method are studied as a heat island measure. Interlocking that at present, used various recycling material as one method to the road surface is developed. The interlocking block is being laid in the sidewalk and parking place. Interlocking that I used to this research can save a rain water into the block, from that is made with a an aperture material unlike usual interlocking. Also, a rain water is able to expect even the effect that easy to penetrate into a foundation and increase cultivation to subterranean water and cause the outflow to subterranean water security and drain controlled. Thereupon, I did examination about the temperature reduction effect by the difference of the specimen with this research.
