摘　　要：通过不同温度下的轻荷载全厚度车辙试验,分析了在大交通量下,轻荷载引起沥青路面车辙的原因。试验及分析结果表明:当温度较高时,由于蠕变变形的积累、轮胎接地压力非均布性及剪应力的作用,轻荷载对沥青路面车辙的影响不容忽视。Based on the light-load total thickness track test on different temperature, this paper has analyzed the reasons that lead to asphalt pavement rutting by light-load and heavy traffic capacity. According to the test results, because of the accu-mulation of creep deformation, the effect of non-uniform distributed tire pressure and shear stress, the influence of light-load and heavy traffic capacity on asphalt rutting can not be ignored.
