Abstract

PURPOSE:To provide the title paving material which is inexpensive, has excellent coatability and gives paved surfaces having excellent high-temperature strength and resistance to rutting, by blending asphalt with an additive component consisting of an ethylene/vinyl acetate copolymer, wax and a petroleum resin. CONSTITUTION:25-55wt% ethylene/vinyl acetate copolymer (a) having a vinyl acetate content of 3-32wt% is blended with 25-50wt% wax (b) having a softening point of 55-100 deg.C, such as paraffin wax, and 10-50wt% petroleum resin (c) such as an alkylstyrene/indene resin obtd. by using higher olefinic hydrocarbons as main starting materials, a petroleum resin obtd. by using cyclopentadiene as a main starting material, etc. to obtain an additive (B) for asphalt. 100pts.wt asphalt (A) is blended with 5-25pts.wt. component B.
