| Abstract: | The loading frequency has a remarkable influence on bituminous mixture fatigue life. It is based on the low loading frequency that the thermal fatigue of the material is simulated, the dissipated energy theory is used to analyze the thermal fatigue of bituminous mixture, and the analysis of damage mechanics is carried on. |
