Abstract

PURPOSE: To provide a rubber-containing asphalt composition having excellent dissolution workability, mechanical strengths and adhesiveness, etc. by adding modified low-molecular weight rubber added with maleic anhydrides to low-molecular weight polyisoprene rubber and crosslinking agent therefor.
CONSTITUTION: Rubber-containing asphalt composition is obtained from modified low-molecular weight rubber by adding maleic anhydride or its derivatives (B) of 0.03W12mol per 100mol of isoprene monomer of low-molecular weight polyisoprene rubber (A) containing more than 70% of cis-1,4 linkage and 8,000W150,000 of molecular weight to the low-molecular weight polyisoprene rubber, and crosslinking agent (C) therefor, wherein (C) includes, for example, potassium acetate, sodium hydroxide, lead oxide, etc., and 0.1W200pts.wt. per 100pts.wt. of modified low-molecular weight polyisoprene rubber. The weight ratio of asphalt to modified low-molecular weith polyisoprene rubber is 99/1W20/80, preferably 99/1W 70/30 in road pavement field, and 95/5W40/60 in sealing and adhesive field.
