基于橡胶粉与SBS复合改性技术钢桥面铺筑沥青混合料耐久性试验研究

Study on the Durability of Steel Deck Pavement Asphalt Mixture Based on Rubber Powder and SBS Compound Modified Technology

为了满足桥面铺装沥青混凝土对沥青结合料的特殊性能要求,提高桥面铺装沥青混凝土的柔韧性,通过对不同掺加比例的橡胶粉与SBS复合改性沥青及其混合料的性能进行试验分析,探讨了橡胶粉对复合改性沥青混合料的增柔增韧、抗剪、水稳定性的影响机理,并推荐了可以显著复合改性沥青混凝土综合使用性能的最佳橡胶颗粒掺量。

In order to satisfy the bridge deck pavement of asphalt concrete special performance requirements of asphalt binder,Improve the flexibility of bridge deck pavement asphalt concrete,by adding different proportions of rubber powder and SBS modified asphalt and composite mix performance test analysis,discusses the composite rubber powder modified asphalt mixture by Sophie toughened,shear,impact mechanism water stability,and recommended significantly modified asphalt concrete composite best overall performance rubber particles content.
