Abstract
Many of the water retention pavements lower their temperature by having cement milk or slag placed in the voids on the surface of pavement absorb rainwater and using the vaporization heat. If there is no rainfall for a long period of time, however, no rainwater is supplied. Constructing facilities for supplying water would cost considerably. Infiltration of rainwater is likely to make muddy and structurally weak roads. This study focuses on the road surface structure and proposes a road surface structure using waterretaining Solpack as a solution. The performance of water-retaining Solpack was evaluated in laboratory tests and various field tests including long-term instrumentation, and its applicability was identified.
