- Abstract:
- A deformation prediction model for the dynamic creep test is deduced based on the linear viscoelastic(LVE)theory. Then, the defect of the LVE deformation prediction model is analyzed by comparing the prediction of the LVE deformation model with the experimental data. To improve accuracy, a modification of the LVE deformation prediction model is made to simulate the nonlinear property of the deformation of asphalt mixtures, and it is verified by comparing its simulation results with the experimental data. The comparison results show that the LVE deformation prediction model cannot simulate the nonlinear property of the permanent deformation of asphalt mixtures, while the modified deformation prediction model can provide more precise simulations of the whole process of the deformation and the permanent deformation in the dynamic creep test. Thus, the proposed modification greatly improves the accuracy of the LVE deformation prediction model. The modified model can provide a better understanding of the rutting behavior of asphalt pavement.
- 基于线性黏弹性理论(LVE)推导出沥青混料在动态蠕变实验中的变形预估模型.然后, 将线性黏弹性变形预估模型和实验结果对比, 分析说明了线性黏弹性预估模型的不足.最后, 为了提高预估准确性, 对线性黏弹性预估模型进行了修正, 使其具有与沥青混合料变形特性相符的非线性特性, 并用实验数据对修正模型进行了验证.结果表明, 线性黏弹性变形预估模型无法模拟沥青混合料的永久变形的非线性特性, 而修正变形预估模型可以准确地预测动态蠕变实验中变形的全过程以及永久变形.说明了所提出的修正方法可以有效地提高线性黏弹性变形预估模型的准确性, 该修正模型可以为沥青路面的车辙预估提供指导.
