Rutting is one of the major distresses of the expressway pavements in China. At present, rut depth is the only evaluation index for rutting at home and abroad. It can’t show the whole information of rut. A rut-meter is developed independently, which is used for inspecting rut of several expressway pavements. The results show that the shapes of rut were different, and the shape of rut affects traffic safety. Multi-indexes are adopted, such as rut depth, rut width, maximum possible water catching area and average rut curvature radius, to describe the characteristics of rut and the relation between rut and traffic safety. The study laid a foundation for more rational new rut index.
