摘要
主要采用MMLS3加速加载试验、低温小梁弯曲试验、冻融劈裂试验和浸水马歇尔试验以及APA疲劳试验分别研究了4种不同级配纤维橡胶沥青混合料的路用性能,研究结果表明,间断级配橡胶沥青混合料具有较好的高稳稳定性、低温抗裂性和疲劳性能,而连续级配橡胶沥青混合料具有较好的水稳定性。研究成果可为实体工程中选择合理的橡胶沥青混合料工程级配类型提供借鉴。
This paper uses MMLS3 accelerated loading tests,bending tests,freeze-thaw splitting test and immersion Marshall test and APA fatigue testto study the road performance of four different graded fiber rubber asphalt mixtures,The results show that: gap- graded asphalt rubber has good stability high stability,low temperature cracking resistance and fatigue properties,and graded asphalt rubber has good water stability. Research results can be a reasonable choice of rubber asphalt mixture gradation works projects to provide the type of entity reference.
