Beschreibung
Zusammenfassung:	The present invention relates to an asphalt composition comprising a linear diblock copolymer. Particularly, an asphalt composition comprising a linear diblock copolymer consisting of a vinyl aromatic hydrocarbon/conjugated diene has superior dispersion, elongation and a high softening point, and an asphalt composition to which a small amount of sulfur compound is further added has more improved dispersion and thus elongation and softening temperature can be improved more effectively.
