通过残留物、老化对回收 SBS 改性沥青性能的影响分析，研究了相应的改进措施，并对旧沥青的回收及再生效果进行了评价。研究表明：少量的矿粉和三氯乙烯均能明显影响回收沥青的性能，研究提出的改进措施能有效减少残留物的含量和回收过程中的老化，保证回收沥青的真实性能；老化使沥青明显变硬，常用的再生剂对 SBS 改性沥青的改善效果有限，过多掺加量将减低沥青的高温性能。

Based on the analysis of residues,aging effects on the performance of reclaimed SBS modified bitumen,corresponding improvement measures was studied,and effectiveness of reclaimed and recycling of aging asphalt effects were evaluated.The test results indicate that a small amount of filler and trichloroethylene can significantly affect the properties of the reclaimed asphalt,and improvement meas-ures proposed in this study can effectively decrease the content of the residues and aging during recove-ring process,ensured the actual performance of reclaimed bitumen.Aging makes the asphalt harden,and the improved effectiveness of common rejuvenator was limited to the properties of the reclaimed bitumen. Adding too much rejuvenator will degrade high-temperature performance of the reclaimed bitumen.
