摘要
文章通过对某试验路段车辙凹陷位置及隆起位置进行钻芯取样试验,分析了沥青路面车辙不同位置处芯样的厚度、毛体积密度、油石比、级配的变化规律,为高速公路沥青路面车辙研究提供参考。
Through the drill core sampling test at the recessed position and uplifting position of testing road rutting,the article analyzed the thickness,gross bulk density, asphalt-aggregate ratio,gradation variation rules of core samples from different positions in asphalt pavement rutting,providing the reference for the rutting research of expressway asphalt pavement.
