| 摘 要： | 根据同济大学提出的四单元五参数模型,采用沥青混合料变形的粘性部分来评价沥青混合料的高温稳定性,认为四单元五参数模型能较好地模拟沥青混合料的高温稳定性,并根据动蠕变实验推出模型中的粘弹性参数,导出了模型中五参数与车辙试验动稳定度之间的关系。

| Abstract: | According to viscoelasticity theory four elements five parameters model developed by the Tongji university is selected to describe the viscoelastic behavior of asphalt binder and asphalt mixtures.The paper adopts the viscous portion of asphalt mixtures deformation to evaluate its thermal stability.The study shows that four elements five parameters model can better characterize the high temperature stability of the asphalt mixtures.The article also deduces viscous parameter of the model according to dynamic creep test,and the connection between the five parameters of this model and dynamic stability in rutting test. |
