| 摘 要： | 借助三轴剪切试验研究了沥青混合料的抗剪性能,采用简单性能试验考察了剪切疲劳作用的影响以及抗剪强度参数与车辙之间的相关性.研究发现:级配类型、沥青用量、沥青性质及试验温度对混合料抗剪强度有显著影响,抗剪强度随着荷戢作用次数的增加呈幂函数递减,抗剪强度参数与抗车辙性能之间呈良好的对数关系.结果表明剪切疲劳产生的流动变形是车辙产生的主要原因.

| Abstract: | The anti-shear properties of asphalt mixtures were studied through triaxial shear test.The influence of shear fatigue on shear strength was analyzed by using triaxial repeated load test.The relationship between anti-shear strength index and rutting index was observed.Analysis result shows that such factors as gradation type,asphalt content,asphalt properties and test temperature have great influence on the anti-shear strength of asphalt mixture.Anti-shear strength decreases exponentially with the increase o... |
