沥青混合料低温粘弹性参数回归初探

Analysis of Visco-elastic Parameters of Asphalt Mixture at Low Temperature

沥青混合料的粘性成分——沥青,是一种感温性极强的材料,通过对典型的沥青混合料进行低温弯曲蠕变试验,并选取Burgers模型中的四项参数代表其粘弹性,采用各个参数的几何意义来求取参数值,可为沥青混合料的低温粘弹性分析提供数据基础。

The binder of asphalt mixture-asphalt is a kind of typical visco-elasic material and the characteristics of the mixtures at low temperature are experimented. Parameters of Burgers model being computed on the basis of this experiment can provide useful information for the future visco-elasic design of asphalt pavement.
