CONSTITUTION: Both sides of a flat yarn cloth sheet 1 of plain weave formed of warp and woof of polypropylene tapes are folded in the shape of a tube, inserting polypropylene tubes as core materials 4' and 4' into the insides of them, and they are fixed by means of adhesives to make core sections 4 and 4. The cloth sheet 1 is fixed on a site for road by means of anchors 6, and pit sand not including coarse particles with a particle size of more than about 5mm is spread uniformly thereupon to form a tamped earth layer 5. In case of raining, the earth layer 5 drain is prevented by the core sections 4 and 4. In stead of above-mentioned earth layer, an organic peroxide prevulcanized natural rubber water dispersion medium is added to beach sand to form a mixture, the mixture is poured onto the cloth sheet 1, and a naturally dried earth caking substance or a river sand spread artificial lawn can be used.
