沥青混合料的粘弹性流动导致沥青路面产生永久变形(车辙)。对于粘弹性体系,永久变形与材料的弹性参数无关,但可通过采用粘性参数的线弹性模型预估出来。为了确定沥青混合料在较大环境变化条件下的粘性,该文引入了一个新的基于常规试验数据的简单理论方法,并将根据此方法得到的车辙预估深度与法国新近的一个足尺试验数据进行对比,结果表明此线性车辙模型的适用性较好。 The viscoelastic flow of asphalt mixture leads to permanent deformation (rutting) of asphalt pavement. For viscoelastic systems, the permanent deformation is independent of the elastic parameters of the material, but can be estimated by using a linear elastic model with viscous parameters. In order to determine the viscosity of bituminous mixtures under large environmental changes, a new simple theoretical method based on conventional test data is introduced. The rut prediction depth obtained from this method is compared with a new full-scale test The results show that the linear rutting model is more suitable.
