超薄沥青混凝土性能研究

Research on Ultra-thin asphalt Concrete Rerforman

介绍了超薄沥青混凝土面层的组成设计、材料和施工要求。通过评价和分析3种不同超薄沥青混合料的各项路用性能,包括水稳定性、高温稳定性、低温稳定性、构造深度以及渗透系数等试验,以确定超薄沥青混合料在高速公路修复中的适用性。研究结果表明,超薄沥青混合料具有优异的路用性能,适用于高速公路维修与养护。

This paper introduces materials,design and construction requirements of ultra-thin asphalt pavement. According to the resuhs of ultra-thin asphalt mixture performance,which include water stability test,low-temperature and high temperature test, texture depth test and permeability coefficient test, the feasibility of ultra-thin asphalt mixture in the freeway rehabilitation is determined. The research shows that ultra-thin asphalt mixture show good performance and can be used in the freeway maintenance.
