Based on vehicle dynamic loading, the rut calculation method is put forward, the influence law of pavement rut is obtained, and the rutting prediction for the test road was performed by employing this method. The results indicated that there is little difference between calculated rutting value and the real one of the test roads, and the maximum error is 9 %. Moreover, their deformation shapes of rutting are almost the same as a whole. Therefore, the proposed rutting calculation method is feasible for the very complex problem of rutting calcula...
