- Abstract:
- The pavement performance of epoxy resin modified asphalt mixtures was investigated by the Marshall test, the indirect tensile test, the rutting test, the three-pointed bending test and the composite beam fatigue test. In comparison with the performance of epoxy resin modified asphalt mixtures, the performance of stone matrix asphalt mixtures(SMA10)was also investigated. The rutting test and composite beam fatigue test results show that the epoxy resin modified asphalt mixtures can improve permanent deformation and fatigue characteristics. They also show lower temperature susceptibility and greater resistance to moisture damage compared to the SMA10. Findings from the research indicate that the epoxy resin modified asphalt mixture provides an optional material for the pavement of long-span steel bridges in China due to profound performance and economic advantages.
- 为了解我国自主研制的环氧树脂改性沥青混合料的路用性能, 采用马歇尔、劈裂、车辙、小梁弯曲和复合梁疲劳等试验, 对其材料特性和路用性能进行了全面的试验研究, 并与SMA10混合料的性能进行了对比研究.车辙和复合梁疲劳试验结果表明, 环氧树脂改性沥青混合料具有良好的高温稳定及疲劳性能;与SMA10混合料相比, 环氧树脂改性沥青混合料具有良好的抗水损害及低温抗开裂性能.研究表明, 新型国产环氧树脂改性沥青混合料以其优异的性能和良好的经济优势为我国大跨径钢桥桥面铺装提供了一种新的铺装材料.
