【Abstract】 Regarding semi rigid base asphalt concrete road as the main object, several main rut estimating and computing methods are applied to analyze the rut estimation by the dynamic vehicle load in the paper. Moreover, the advantages and disadvantages are compared among the computing method. Based on analysis of rut formation and influence factor to the rut, and through great deal of experimental data, it is testified that viscoelasticity finite element theory and method are the best to estimate the rut depth and analyze the experimental data, moreover an effective rut estimating method is put forward in the paper for semi rigid base asphalt concrete road in China.更多还原
