PAVEMENT USING WASTE CERAMIC FOR PLAYGROUND AND ITS CONSTRUCTION METHOD

摘要

The present invention relates to a playground pavement material using waste ceramic and a construction method thereof. The playground pavement material of the present invention comprises: a substratum formed by laying waste ceramic; a subsidiary substratum piled up by laying waste ceramic on the top of the stratum; a surface layer piled up by laying a first mixed composition made by mixing soil cement, silica sand, and waste ceramic on the top of the subsidiary substratum; and, a top layer piled up by laying a second mixed composition made by mixing silica sand and soil cement on the top of the surface layer. The playground pavement material of the present invention performs a stable humidifying function to absorb moisture when it rains, to constantly supply moisture to the surface of the surface layer when it is dry, and to delay drying due to the characteristics of porous waste ceramic, and minimizes the generation of scattered dust. The playground pavement material of the present invention allows usage of the playground in a pleasant environment by emitting far-infrared radiation for helping human metabolism and negative ions for removing hazardous substances in the air.
