| Abstract: | The drawbacks of the quantitative indicators of the damage and the grading of distress density in the present standard were analyzed, and the rational conversion coefficient of pavement distress was evaluated. On the basis of analyzing the relation between the damage and condition of pavement, and by the maintenance treatments to pavement crack, the amended method of grading the crack density was put forward. Moreover, the criterion of serious degree of rutting and conversion coefficient of distress pavement were suggested in the paper. |
