| 摘 要： | 针对国内沥青路面早期破坏现象,尝试采用添加养护剂的方式延长路面使用寿命并对其进行性能恢复,采用SHRP标准中动态剪切指标G'/sinδ来评价老化沥青及不同养护剂参量下沥青胶结料高温流变性能,并通过该指标判断养护剂参量对老化沥青高温流变性能恢复的阀值点,可为沥青路面的养护提供借鉴.

| Abstract: | In this paper, the author tries to add the curing agent to extend pavement life and recovery pavement performance for asphalt pavement early failure phenomena, use SHRP standard dynamic shear indicator to evaluate high-temperature rheological property of aging asphalt binder and different curing agent parameters, and determine threshold point through this indicator for aging asphalt high temperature recovery in different curing agent parameters. It is useful to provide available reference for asphalt pavement maintenance. |
