摘要
应用半圆弯曲试验,基于能量原理,研究了不同应力比作用下AC-13沥青混合料的疲劳寿命与累积耗散能之间的关系。结果表明:在不同应力比作用下,两者之间存在良好的线性关系。
The relationship between fatigue life and accumulative dissipated energy affected by different stress ratios was studied based on energy theory with semi-circular bending tests. The results indicate that the fatigue life of asphalt mixture and accumulative dissipated energy remain a linear relationship under various stress ratios, and a new model for prediction of fatigue life of asphalt mixture was built.
