摘要
利用直接剪切试验结合无侧限抗压试验和劈裂试验,对几种不同粒径沥青混合料的抗剪性能进行了研究,并且对比分析了它们的抗剪强度、抗剪参数与高温车辙动稳定度、马歇尔稳定度、空隙率等之间的关系。结果表明,利用直接剪切试验结合无侧限抗压试验和劈裂试验能够很好地评价沥青混合料的抗剪强度并获得沥青混合料的C和φ值,而沥青混合料的抗剪性能可以很好地反映其抗车辙性能。
The anti-shear characteristics of different asphalt mixtures are studied by the direct shear experiment, compression experiment and splitting experiment, and the relations between shear strength,anti-shear index and dynamic stability, Marshall stability, air voids are analyzed in this paper. The experiment results indicate that the direct shear experiment, compression experiment and splitting experiment can accurately evaluate the shear strength and the C and φ value of asphalt mixtures. And theanti-shear characteristics can accurately reflect the anti- rutting characteristics of asphalt mixtures.
