摘要
沥青胶结料的老化是影响沥青路面使用性能的一个重要因素 ,应用旋转薄膜烘箱( RTFOT)对沥青进行短期老化 ,然后再应用压力老化仪 ( PAV)对其残留物进行不同时间的老化。对经过不同程度老化的沥青 ,进行常规的三大指标试验和粘度试验 ,探讨老化对沥青胶结料常规指标的影响 。
The aging of asphalt binder is an important factor to asphalt pavement service property. Short-term age to asphalt binder by using RTFOT was applied in the research, then various hours age to the residue by using PAV was applied. It was studied that the effects of aging on conventional index of asphalt binder by testing the penetration,softening point,ductility and viscosity on the PAV residue.
