国内外沥青路面抗车辙研究动态

Research on Rutting Resistance of Asphalt Pavement at Home and Abroad

车辙危害交通安全,是沥青路面的技术难题,也是世界各国普遍关注的路面破损形式之一。多年来国内外道路技术工作者为此做了大量的工作,从路面结构、路面材料、混合料组成设计、车辙控制指标等方面进行了大量的理论分析和试验研究,取得了一定的成果。但是由于超载、交通量激增等原因,车辙目前仍是世界性的难题之一。

The damage of rut to traffic safety is a technical tricky problem of asphalt pavement, also one of the forms of pavement damage, which has gained widespread concern throughout the world. Much has been done by the road technicians all over the world in recent years. Lots of theorical analysis and test research have been conducted in pavement structure, pavement material, mixture composition design and rut control index, rusulting in certain amount of achievement. Rut issue is still one of the worldwide tricky problems because of overload and traffic surgeetc.
