摘要： PURPOSE: A drainage asphalt is provided to enhance arsenate resistance, weather resistance, water resistance, fluidity resistance and strength of aggregate, and to improve security for driving vehicles. CONSTITUTION: A drainage asphalt is manufactured by adding 4.5-5.5 wt.% of thermoplastic styrene-butadiene-styrene copolymer having the average molecular weight of 70,000-110,000 by weight of asphalt to the aggregate mixture comprising 85-87 wt.% of aggregate, 8-10 wt.% of sand, and 4.5-5.5 wt.% of filler. Then, 11-13 wt.% of modifier is additionally added in order to manufacture modified asphalt with a high viscosity. Preferably, the viscosity of the modified asphalt at 60 deg.C is 200,000 poises and over.
