摘　　要：首先对黑龙江省大齐高速公路某路段车辙病害情况进行调查。对车辙严重路段进行现场钻芯取样。通过对芯样的厚度、密度、沥青含量等指标分析,大齐公路产生车辙的主要原因是:部分路段的低温压实或者路面施工的变异性导致的沥青路面面层的压实度不足而产生压密车辙。A rutting investigation has been carried on the Daqing-Qiqihaer Expressway in Heilongjiang Province,as well as the core boring sampling on heavy rutting sections.Based on the analysis of the indicators of the core sample,such as the core boring sample thickness,density,and asphalt content,this paper concludes that pavement construction variability and inadequate compaction of asphalt pavement surface has caused the rutting in some sections.
