Abstract In the present study, the finite element method was applied to model the fatigue behavior of glassphalt and conventional mixtures. In order to assess the efficiency level of the presented model, all mixtures were tested using 4-point bending test. Accordingly, it can be seen that there is high consistency between the laboratory results and outputs of 3D finite element model presented in this study in both conventional asphalt and glassphalt mixes. The estimation models have predicted the fatigue life of similar samples with only a 3% error. Also, laboratory results showed a 5% improvement in the fatigue performance of the glassphalt rather than conventional mixtures.

含沥青玻璃废料疲劳预测模型的数值与实验室研究

摘要 在本研究中，有限元方法被应用于模拟玻璃沥青和常规混合物的疲劳行为。为了评估所提出模型的效率水平，所有混合物都使用 4 点弯曲试验进行了测试。因此，可以看出，在常规沥青和玻璃沥青混合料中，实验室结果与本研究中提出的 3D 有限元模型输出之间具有高度一致性。估计模型预测了类似样品的疲劳寿命，误差仅为 3%。此外，实验室结果表明，与传统混合物相比，玻璃沥青的疲劳性能提高了 5%。
