| 摘 要： | 沥青是一种典型的粘弹性体，其粘弹性特性对沥青路面的使用性能具有重要的影响。文章以粘弹性力学理论为基础，采用Burgers模型模拟直接拉伸试验测定沥青粘结料的粘弹性特性，提出确定粘弹性参数的非线性模型，并介绍利用大型统计软件SPSS求解粘弹性参数的方法。

| Abstract: | Asphalt binder is a classic viscoelastic material and asphalt pavements' performance are affected greatly by its viscoelastic properties.Based on the theory of viscoelasticity,Burgers model has been used to simulate the viscoelastic properties tested by Direct Tension Test and the nonlinear program model is given which can determine viscoelatic parameters,then SPSS was used to determine the viscoelastic parameters. |
