Study On The Standard Of Rutting Maintenance Of Asphalt Pavement Based On Safety

The various performances would to be deteriorated along with extension of operating period, thus the service level of the pavement was lowered in the asphalt pavement.To the user, they can detect directly function performances about roughness, slide, noises instead of strength and stability of road structure. The users are more care for difficult grade of handling and stability of vehicle when he is driving on the road. But, the surface of road would occur significant displacement by rut arising, not only the smoothness of road would be destroyed, but also riding comfort would be weakened, furthermore riding stability would be endangered by the rut likely railway. Thereby, the riding stability of vehicle on the road that rut have occurred is studied in this paper, it aims that riding quality would be reflected when rut had occurred, and to evaluate rut according to riding stability.The rutting evaluation indexes method proposed laid the certain foundation for researching the relationship of rutting and driving security,and provided the certain basis for maintenance, and made the important。But, this paper just drew the conclusion that the trend of vehicle stability would be change because shorting of the whole suit of parameters, the relation of rut and stability was not offered, the work about these would be continued.
