摘要
文中研究不同掺量抗车辙剂下(0.25%、0.35%、0.45%、0.55%)沥青混合料的物理参数、动稳定度、劲度模量及渗水系数的变化规律,确定最佳的抗车辙剂掺量,对最佳抗车辙剂掺量下的沥青混凝土进行不同类型路用性能的表征。结果表明,最优抗车辙剂掺量为0.5%。与普通沥青混合料相比,掺入抗车辙剂后,高温性能增幅达到173%,低温性能提升幅度达15.9%,抗渗性能提升了31.5%。
In this paper,the high and low temperature properties and physical indexes of asphalt mixture under different rutting agents(0.25%,0.35%,0.45%,0.55%)were studied,and the best amount of anti-rutting agent was determined.The high temperature performance,low temperature performance and impermeability of asphalt mixture prepared with the optimum amount of anti-rutting agent weree valuated.The results show that the optimal dosage of anti-rutting agentis 0.5%.Compared with the ordinary mixture,after adding antir-utting agent,the high temperature performance of AC20 mixture increased by 173%,low temperature performance increased by 15.9%,and impermeability increased by 31.5%.
