摘要
文章针对高速公路流动性车辙病害成因,将基于天然砂、石屑和机制砂三种不同细集料的沥青混合料抗剪强度进行对比分析,研究细集料对沥青混合料抗剪切性能的影响规律,并提出细集料优化配比方案,为沥青路面抗车辙设计和工程实践提供参考依据。
Aiming at the cause of fluidity rutting disease of expressway,this paper makes a comparative analysis of the shear strength of asphalt mixture based on natural sand,stone chips and mechanism sand,and studies the effect of fine aggregate on the shear performance of asphalt mixture.The optimal proportioning scheme of fine aggregate is put forward to provide reference basis for rutting resistance design and engineering practice of asphalt pavement.
