摘　　要：制备MY改性沥青,对改性沥青的针入度、软化点以及延度进行检测,同时,对改性沥青的抗老化性能、与集料的粘附性能进行测试。测定改性沥青混合料的动稳性能和水稳性能。实验结果表明,MY沥青砂添加剂加入改善了沥青的高温性能和稳定性,可以提高沥青混合料的动稳定度和水稳定性能。The MY modified asphalt was prepared, and the penetration, softening point and ductility of the modified asphalt were tested. At the same time, the anti-aging performance of the modified asphalt and the adhe-sion property with the aggregate were tested. Determine the dynamic stability and water stability of the modified asphalt mixture. The experimental results show that the addition of MY asphalt sand additive improves the high temperature performance and stability of asphalt, and can improve the dynamic stability and water stability of as-phalt mixture.
