Abstract:
The present invention relates to an asphalt modifier including a main chain of a vinyl aromatic hydrocarbon-conjugated diene block copolymer, and more particularly, to an asphalt modifier capable of effectively improving low-temperature properties, high-temperature properties, storage stability, and the like of an asphalt composition due to excellent compatibility with the asphalt composition when a vinyl aromatic hydrocarbon-conjugated diene block copolymer containing a certain multifunctional group is used as the asphalt modifier, and an asphalt composition including the same.

Claim (Index 6):
A method of preparing an asphalt modifier of  claim 1 , comprising:\n preparing a vinyl aromatic hydrocarbon block by polymerizing a vinyl aromatic hydrocarbon-based monomer in a hydrocarbon-based solvent using a polymerization initiator; preparing a vinyl aromatic hydrocarbon-conjugated diene block copolymer by mixing a polymerization initiator and a conjugated diene monomer with the vinyl aromatic hydrocarbon block and polymerizing the resulting mixture; and performing a coupling reaction by mixing a coupling agent with the vinyl aromatic hydrocarbon-conjugated diene block copolymer.
