摘要： The present invention is a polymer modified bituminous composition having improved phase stability, heat aging and viscosity characteristics. The bituminous compositions are blends comprising bitumen and from about 0.5 to about 25% of a novel anionic block copolymer where one of the blocks is a controlled distribution copolymer of a conjugated diene and a mono-alkenyl arene having a specific arrangement of the monomers in the copolymer block. The composition of the invention is useful for paving, roofing felts, water-proof membrane, adhesive, mopping asphalt, carpet backing and pipe coating applications.
