Abstract
To provide an asphalt modifier which further improves crack resistance while securing solubility to asphalt.SOLUTION: An asphalt modifier includes an elastomer (A); an elastomer (B); and an aromatic oil, and is to be mixed with asphalt by a plant mix method, where the elastomer (A) is a styrene-butadiene-styrene block copolymer having a melt flow rate at 190°C of 2-5 g / 10 min., a melt flow rate at 200°C of 10-15 g / 10 min., and a styrene content of 35-40%, 60-80 pts.wt. of the elastomer (A) is included, and 20-40 pts.wt. of the elastomer (B) is included when a total of the elastomer (A) and the elastomer (B) is 100 pts.wt.SELECTED DRAWING: None
