| 摘 要： | 总结并评价了沥青混合料抗剪试验方法、抗剪机理及抗剪设计研究现状,对9种剪切试验方法的分析和评价有助于设计、施工和科研人员正确选用这些试验方法。混合料剪切强度由沥青胶泥的性质、集料和沥青界面的剪切强度和集料之间的嵌挤情况共同决定,为提高混合料抗剪性能指出了方向。抗剪设计在应用于工程前尚需深入研究容许剪应力法中相关系数的确定、基于抗剪性能的车辙预估模型的标定等问题。 |
| 关 键 词： | 沥青混合料 车辙 抗剪试验 抗剪强度 |

| Abstract: | The paper summarized and evaluated asphalt mixture anti-shear test method, anti-shear mecha-nism and the anti-shear design reasearch recently. The analysis and evaluation of 9 test methods is helpful for relat-ed personnel to choose these test methods appropriately. The properties of asphalt grout, anti-shear strength be-tween asphalt and aggregate interface, and interlocking of aggregates, joindy decide HMA (hot mix asphalt) anti-shear strength and are the orientation to improve HMA anti-shear properties. Further researches are needed before anti-shear design is used in engineering to solve the problems such as the determination of relevant coefficient in tol-erable shear stress test method and calibration of rutting prediction models based on HMA anti-shear behaviors. |
| Keywords: | asphalt mixtures rutting shear test anti-shear strength |
