Thiopave温拌改性沥青在重载交通路面工程中的应用研究

Application Research of Thiopave Warm-mix Modified Asphalt in Heavy-load Traffic Pavement Engineering

文章针对HMA重载交通路面的主要破坏特征,通过对Thiopave改性沥青路用性能的研究,开展了Thiopave温拌改性沥青混合料配合比设计与优化,并将其应用于试验路铺筑中。通过效果评估分析,发现用Thiopave温拌改性沥青处治重载交通特殊路段,具有在技术上、经济上和环境上的可行性,同时还具有施工简单、不增加施工成本等优点。

In view of the main failure characteristics of HMA heavy-load traffic pavement,this article conducts the design and optimization of mix ratio for Thiopave warm-mix modified asphalt mixture by studying the road performance of Thiopave modified asphalt,and applies it to the test road pavement.Through the effect evaluation and analysis,it is found that the use of Thiopave warm-mix modified asphalt to treat the special heavy-load traffic road sections has technical,economic and environmental feasibility,and also has the advantages such as simple construction and no increase in construction cost.
