Summary of the New Rutting Tests of China

Abstract

The asphalt pavement is the mainstream pavement structure of the expressway in our country. But it is investigated that rutting disease appeared even though the asphalt mixture was test qualified. With this instruction, the standard rutting test method has difficult in satisfying the complex working condition of asphalt pavement. In order to solve these, some new rutting test methods which are in accordance with privileged conditions have been proposed from theory and simulation test by many scholars’ deeper research, including lots of feasible methods. By summarized the new anti-rutting methods of asphalt pavements and described all kinds of basic principles and engineering applications, the deficiency of the new rutting test methods was pointed out and the development direction was proposed.
