PURPOSE: A water-absorption waterproof asphalt adhesive composition is provided to ensure excellent adhesive property, abrasion resistance, durability, aging resistance, and persistent elasticity and to secure excellent water resistance. CONSTITUTION: A water-absorption waterproof asphalt adhesive composition comprises 5~60 weight% petroleum asphalt, 1~20 weight% absorptive high molecule resin, 5~20 weight% urethane rubber, 20~50 weight% surface-treated inorganic filler, and 1~20 weight% isocyanate-based compound. The absorptive high molecule resin is one kind selected from a graft copolymer of starch-acrylonitrile, a graft copolymer of cellulose-acrylonitrile, and an acrylic acid and polyvinyl block copolymer. |
