摘要
运用Matlab软件对重复荷载蠕变试验下的试验数据进行分析和延伸,得到不同温度和荷载下沥青混合料的永久变形规律。基于修正Burgers模型,建立沥青混合料永久变形预估模型,得到三维曲面下沥青混合料的永久变形规律。
Based on the analysis and extension of the experimental data from repeated load creep tests by using Matlab software, the permanent deformation laws of asphalt mixture under different temperature and load are obtained. Based on modified Burgers model, the perm - anent deformation prediction model of asphalt mixture is established to obtain the permanent deformation laws of asphalt mixture under three - dimensional surface.
