摘要： A bituminous composition comprising a bituminous component and a block copolymer composition which comprises at least one of the group consisting of linear triblock copolymers, multi-armed block copolymers, and diblock copolymers, which block copolymers comprise at least one block of a monovinylaromatic hydrocarbon (A) and at least one block of a conjugated diene (B), wherein the block copolymer composition which is present in an amount in the range of from 1 to 10% wt, based on total bituminous composition has a vinyl content of at least 25% by weight, based on the total diene content, and any diblock copolymer (AB) present has an apparent molecular weight in the range of from 60,000 to 100,000.
