ABSTRACT:
A soil, which has been regulated in particle-diameter, is blended with a hydraulic material and water or an aqueous solution of synthetic resin emulsion, so that a moisture content may be 1.2 to 1.5 times an optimum soil compacting moisture content, and then stirred and followed by subjecting to a rolled fill which is followed by watering or spreading an aqueous solution of a soil-agglomerating agent on the mixture, which was subjected to the rolled fill, at least one time within 1 to 5 days after the completion of the rolled fill and further watering at least one time within 7 to 21 days after the completion of the rolled fill respectively, whereby an ideal sportssurface and the like showing not only a water-permeability but also a preferable compression strength and bending strength and showing no frost heaving is obtained.
