摘　　要：为探究老化SBS改性沥青再生利用的可行性。采用薄膜烘箱试验对室内制备的SBS改性沥青进行老化,通过添加自制再生剂对老化SBS改性沥青进行再生,对原样与再生SBS改性沥青进行常规试验、疲劳试验,并对其进行二次老化,对比分析原样与再生SBS改性沥青的常规性能、抗疲劳性能及抗老化性能。试验与分析结果表明:老化SBS改性沥青的再生利用是可行的,再生SBS改性沥青抗疲劳性能与抗老化性能在一定程度上甚至优于原样SBS改性沥青。In order to explore the aged SBS modified asphalt recycling feasibility,The TFOT test was carried out.Recycled asphalt was obtained by adding rejuvenation agent.The routine test,fatigue test,TFOT test was carried out to recycled asphalt.The performance comparison between unaged SBS modified asphalt and recycled asphalt shows that the aged SBS modified asphalt could be re-used by regeneration method,and the anti-aging performance and the anti-fatigue performance of recycled asphalt is better than that of unaged SBS modified asphalt.
