本文介绍了沥青混合料用抗车辙剂的定义、作用原理与性能特点,并对掺加不同品牌、掺量抗车辙剂的沥青混合料高温性能进行测试,对比分析试验数据,确定抗车辙剂的合理用量,结合抗车辙剂沥青混合料的现场施工情况提出抗车辙剂沥青混合料施工控制关键技术与混合料高温性能指标。结果表明,抗车辙剂的加入并不增加混合料沥青用量,在沥青混合料中适量掺加抗车辙剂能大大提高沥青混合料的高温性能,但施工中需对拌和、摊铺、碾压温度及相关工艺等作出适当调整,以确保工程质量。
This paper introduces the definition, principle of action and performance characteristics of anti-rutting agent used in asphalt mixture, and tests the high temperature performance of asphalt mixture mixed with different brands and anti-rutting agents. By comparing the experimental data and determining the anti-rutting agent Based on the field construction of anti-rutting agent asphalt mixture, the key technologies of anti-rutting asphalt mixture construction control and the high temperature performance index of mixture were put forward. The results show that the addition of anti-rutting agent does not increase the amount of asphalt mixture, the appropriate amount of anti-rutting admixture in asphalt mixture can greatly improve the high temperature performance of asphalt mixture, but the construction of mixing, paving, rolling temperature And related technology to make appropriate adjustments to ensure the quality of the project.
