| Abstract: | Experiments were adopted to simulate shear fatigue performance of asphalt mixture under different loading spectrum.Strength degradation model is applied for predicting shear fatigue life of asphalt mixture under random loading spectrum.The result shows the model is reasonable and practicable.So the research can provide a basic reference for pavement performance prediction and optimization of maintenance decision. |
