Modified asphalt composition

摘要: PURPOSE: To obtain the subject composition excellent in resistance to fluidity at elevated temperatures, crack and high-temperature storage stability, useful esp. for paving heavy traffic roads, by blending asphalt with two kinds of high-molecular component a thermoplastic elastomer specified proportions. CONSTITUTION: This is obtained (A) 100 pts.wt. an pref. 100-20000 poise viscosity 60°C (B) 0.5-4 such as olefin copolymer having functional group epoxy (pref. made from 25-90wt.% ethylene, 65-9.5wt.% (meth)acrylic 1-10C alkyl ester 10-0.5wt.% unsaturated epoxide), (C) second reactive B carboxylic acid (anhydride) group, (D) 2-6 polyolefin or diene elastomer.
