| Abstract: | The paper briefly describes the forming mechanism of asphalt pavement and the preventive measures, as well as introduces the function and types of anti-rut agent. Through immersion Marshall test, freeze-thaw splitting test, rut test and bending test of small beam, it is proved that the addition of anti-rut agent can remarkably enhance the dynamic stability of asphalt concrete, meanwhile improve the crack resistance in low temperature and water stability. The application of anti-rut agent in practice of expressway construction obtains good effect. |
