    摘要: A modified asphalt composition comprising a naphthenic asphalt, and a high-vinyl block copolymer is presented. The modified asphalt composition is prepared by combining a naphthenic asphalt and a high-vinyl block copolymer. Further an asphalt concrete is presented, such concrete comprises an asphalt, a functionalized block copolymer, and a siliceous aggregate. A diblock copolymer is presented, such copolymer comprises a vinyl block comprising conjugated vinyl aromatic units, a diene block comprising conjugated diene units and substantially devoid of a tapered block section between the vinyl block and the diene block wherein the diblock copolymer comprises a vinyl content of at least about 20%, and a molecular weight of at least about 50,000.
