摘 要: 沥青路面车辙是多因素综合作用的结果。本文从混合料角度分析了影响沥青混合料高温抗车辙性能的因素,并通过不同因素条件下沥青混合料高温车辙试验,分别以动稳定度和总变形量作为参考序列,对影响因素进行灰关联分析。研究认为,沥青混合料空隙率和矿料4 75mm筛孔通过率对于混合料高温稳定性有重要影响。 The rut depth of asphalt pavement is effected by many factors.In this paper,the affecting factors on thermal stability and rut resistance property of asphalt mixtures are discussed.Based on the wheel rutting test for different type asphalt mixtures at high temperature,gray correlation degree between each factor and dynamic stability and total plastic deformation was analyzed respectively.The results show that percent air voids in asphalt mixtures and the percentage of 4.75mm sized aggregate passing through the screen have great influence on asphalt mixtures thermal stability and rut resistance property.
