Abstract

A block copolymer composition for asphalt modification which is excellent in solubility in asphalt and high-temperature storage stability, has a low melt viscosity, and attains excellent asphalt properties, especially torsion resistance; and an asphalt composition. The block copolymer composition for asphalt modification comprises (I) a block copolymer comprising at least two polymer blocks formed mainly from an aromatic vinyl compound and at least one polymer block formed mainly from a conjugated diene and (ii) a block (co)polymer which comprises one or more aromatic vinyl polymer blocks as an essential component and optionally further contains one or more polymer blocks formed mainly from a conjugated diene and in which the peak molecular weight thereof in terms of standard polystyrene, as measured by gel permeation chromatography (GPC), is less than 1/3 the peak molecular weight of the block copolymer (I), the (I)/(ii) proportion being (95-70)/(5-30) (by weight). The asphalt composition is obtained by adding the modifying composition to asphalt.
