橡胶改性道路沥青及其微观结构

Modification of asphalt with rubbers for pavement and their microstructure

介绍了橡胶改性道路沥青以达到高性能的改性技术 ,主要有废橡胶粉改性技术、丁苯橡胶乳液改性技术、SBS改性技术等 ,各类技术都能有效地提高沥青的路用性能。改性沥青的微观结构研究表明 ,改性机理是相容性改性、溶胀网络改性。

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.
