Abstract
One aspect of the present invention provides an additive composition for polymer-modified asphalt including a block copolymer having a radial structure and a copolymer of an aromatic vinyl compound of which two ends have different molecular weights and a conjugated diene compound, and a method of preparing the same. When asphalt is prepared using the additive composition for polymer-modified asphalt, properties of the existing polymer-modified asphalt may be maintained while content of sulfur may be reduced, viscosity may decrease, and thereby processability and pavement performance may be improved.
