摘要
应用抗车辙沥青混合料的主要目的在于减少车辆荷载作用下沥青混凝土产生的应变及变形,减少变形中的不可恢复残余部分,提高沥青路面高温抗变形能力,延缓车辙的产生。研究了通过干法加入抗车辙添加剂,提高高温稳定性的沥青混合料。实践证明,使用抗车辙沥青混合料技术后未出现车辙、推移和拥包等高温病害,改善效果显著。
The main aim of using anti-rutting additive in asphalt mixture is reduce vehicle load produced by the strain and the deformation of irreversible residual, improve the high temperature deformation resistance of asphalt pavement, as well as delay the produce of the rut. This paper refers to the anti- rutting additive of asphalt mixture through the dry process to improve the high-temperature stability of asphalt mixture. Practice proves that the anti-rutting additive can effectively improve the performance of asphalt mixture under high temperature without rutting, elapse or lump.
