Abstract:
Disclosed are block copolymer formed by block-copolymerizing vinyl aromatic hydrocarbon and conjugated diene compound and asphalt modifier composition including specific functional additives. Asphalt modifier composition according to the present invention is rapidly dissolved in asphalt without substantially lowering a softening point of asphalt, making it possible to form uniform asphalt composition and improve the productivity of the asphalt composition.
