摘　　要：通过室内试验分析研究了不同橡胶粉掺量对基质沥青的改性效果,分析了橡胶沥青的高温性能,水稳定性,耐久性性能指标。结果表明:在试验范围内,轮胎橡胶粉能显著提高沥青混合料的高温性能,轮胎橡胶粉掺量越高,混合料的高温性能越好;橡胶沥青混合料的残留稳定度要比基质沥青混合料有所提高,体现了橡胶沥青较好的抵抗水损害的能力;橡胶粉改性沥青的耐老化性能也有了一定的提高。The effect of crumb rubber with different contents on the performance of asphalt rubber was studied through a series of tests .The high temperature performance , water stability , durability performance of rubber as-phalt were analyzed .The results show that rubber powder can remarkably improve the high temperature performance of asphalt mixture .The higher tire rubber powder content , the better the performance of the high temperature of mixture.The residual stability of rubber asphalt mixture was better than the matrix asphalt mixture ＇s, which embod-ies the rubber asphalt has good resistance for water damage .Rubber powder modified asphalt aging resistance per-formance was improved .
