Rutting is one of main damages in the asphalt pavement. The features of rutting in each asphalt pavement layer were analyzed by surveying the rutting depth, excavating transverse profile section and boring samples in the typical sections of expressways in which different degree rutting damages appeared. With the combination of the indoor rutting test on the sample from a corresponding location of road shoulders, the influence of the high temperature stability of each asphalt pavement layer on rutting was analyzed with the method of ANOVA (Analysis Of Variance). The result indicated that the stability of the middle layer impacted the rutting development most. Finally, the relationship between the RD (rutting depth) and the DS (dynamic stability) of each asphalt pavement layer was built with the nonlinear regression method. The controlling Criterion of the DS of the bottom layer asphalt mixture has been put forward according to the regression equation.
