PROBLEM TO BE SOLVED: To provide a soil paving material capable of maintaining water permeability or water retentivity and preventing a variation in the quality of products. SOLUTION: The soil paving material uses, as an aggregate, the mixture of waste tile with a grain diameter of 0-10 mm which is pulverized and split and single-grained silica sand with a grain diameter of 0.3-1.2 mm. A cement solidification material is mixed with the aggregate at a rate of 6-20 wt.%. Consequently, a chamotte maintains water permeability or water retentivity, and a variation in the quality of products can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
