Abstract: Asphalt modified with three kinds of rubbers, such as reclaim rubber, synthetic or natural rubbers, block copolymers（ SBS） ,was reviewed with 18 references . Rubber modification could efficiently improve the performance of asphalt for pavement. Four kinds of modification mechanisms were presented and compared . They could partly explain the improvement of asphalt modified by rubbers.
Keywords: asphalt for pavement; rubber; modification;microstructure; modification mechanism;review
