Abstract:
Disclosed is a paving resin composition which comprises a thermoplastic resin in small lumps, containing 30 to 70% by weight of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 20 to 45% by weight and a melting temperature of 40 to 100° C. The paving resin composition of the present invention is melted within a short time, excellent in wettability and adhesion property to aggregates, and capable of providing a paved face excellent in durability free from problems of deformation during summer and cracking during winter. Moreover, the paving resin composition of the present invention can be thrown directly to a mixer without being passed through a measurement apparatus and accordingly, washing work of the measurement apparatus or pipes is made unnecessary and the workability is thus significantly increased.
