摘　　要：为了分析长大纵坡沥青路面路用性能不同于常规路面的特点,通过全厚式车辙板试验及对其动稳定度指标的讨论、层间直剪试验分析层间容许剪应力、复合式小梁进行小梁弯曲试验对路面抗弯拉强度以及破坏指标进行分析,提出了以动稳定度评价高温稳定性,以路面层间容许剪应力评价抗剪性能,以破坏应变控制低温抗裂性能的具体指标。可做为设计与施工的指导。In order to analysis the different performance between large longitudinal slope asphalt pavement and the conventional pavement.Through all thick type plate test and its dynamic stability index discussion,interlayer direct shear test analysis between layers allow shear stress,compound trabecular trabecular bending test for pavement on bending tensile strength and damage index analysis,put forward the dynamic stability evaluation with high temperature stability,the road surface layer between allow shear stress evaluation shear performance,to damage the strain to control the low temperature anti-cracking performance of concrete index.Can be used as a guide to design and construction.
