抗车辙剂在呼包高速改扩建路面工程中的应用研究

Research on Application of Anti-rutting Agent Used in Reconstruction and Expansion Pavement of Huhhot-Baotou Expressway

结合呼包改扩建工程,选用两种抗车辙剂,采用0.0%、0.2%、0.3%、0.4%四个不同掺量,分别进行了动稳定度车辙及汉堡轮辙试验。试验结果表明:掺加抗车辙剂后沥青混合料的高温稳定性有了明显提高,综合汉堡与动稳定度车辙试验结果建议工程应用中抗车辙剂的掺量应大于0.25%。

In reconstruction and expansion engineering of Huhhot - Baotou expressway, we chose two kinds of anti - rutting agent and adopted O. 0%, O. 2%, O. 3%, O. 4% four different contents for dynamic stability and Hamburg wheel -tracking test. The results showed that high temperature stability of asphalt mix- ture had been significantly improved after mixing anti -rutting agent, Hamburg and dynamic stability rutting test resutts suggested that anti - rutting agent applications of dosage should be greater than 0.25% in engineer- ing.
