摘　　要：车辙是目前高速公路沥青路面主要病害之一,通过对试验路钻取芯样,分别测量芯样的高度、毛体积密度、油石比、级配等,得出荷载作用不同位置处相应指标的变化规律,为高速公路沥青路面车辙研究提供参考。Currently,rutting is one of the main diseases of asphlat pavement of expressway.Through drilling the tested road for core sample,height,bulk density,oil and stone ratio and grading of core sample are respectively measured and changing rules of correspongding indexes at different positon with load are abtained,providing references for reseach on asphalt pavement rutting of expressway.

关 键 词：车辙 毛体积密度 油石比 级配
