摘　　要：分析SBS改性沥青老化再生研究的重点、难点,通过对比沥青老化前后化学组分与物理性质变化,结合国内外研究成果,总结SBS改性沥青老化机理,归纳沥青老化理论;而后依靠组分调节理论与相容性理论,指出SBS改性沥青再生的方向,通过试验和理论两方面证实传统沥青再生技术适合于改性沥青再生利用。The key points and difficulties of SBS modified asphalt aging and recycling research are analyzed.Through the comparison of chemical component and physical property changes before and after aging and combined with the research results at home and abroad,SBS modified asphalt aging mechanism and theory are summarized.Based on component regulatory theory and compatibility theory,recycling direction of SBS modified asphalt is pointed out.The experiment and theory both show that recycling technology for traditional asphalt is suitable for the recycling utilization of modified asphalt.
