PURPOSE: To provide a compsn. which can be used as a paving material having excellent resistance to cold and wear and safety without using asphalt, by adding siliceous sand and natural fiber fragment or granulated corn or fruit husk to a specified thermoplastic resin.
CONSTITUTION: Siliceous sand and natural fiber fragment or granulated corn or fruit husk are added to a thermoplastic resin component mainly composed of 50W90wt% thermoplastic resin having a melt index of 100 or below and 50W 10wt% thermoplastic resin having a melt index of 150 or above. Examples of the thermoplastic resins are an ethylene/vinyl acetate copolymer resin, polypropylene resin, polyethylene resin, polyester resin, etc. Preferred natural fibers include short fibers of bamboos, cotton and flax having high heat resistance and tensile strength. The fiber length is pref. 10cm or shorter. Granulated rice hull, wheat chaff, buckwheat chaff, walnut shell, ume (Japanese apricot) core or apricot core having a particle size of 40 mesh or above is preferably used.
