摘　　要：为探求POE(乙烯/辛烯共聚物)改善SBS改性沥青老化性能的机理,通过沥青流变指标分析、荧光显微分析及红外光谱分析,对SBS改性沥青、POE/SBS复合改性沥青及其短期、长期老化后的残留物进行性能测试。结果表明,POE分子流动性能优良,掺入SBS改性沥青后,POE可与SBS共混相容,使SBS在基质沥青中分散更均匀、溶胀更充分,所形成相容体系延缓了SBS老化降解程度。For exploring the influence of POE（Poly Olefin Elastomer）on the aging properties of SBS modified asphalt, the index of rheological analysis, fluorescence microscope analysis, as well as the infrared spectroscopy measurement of the SBS modified asphalt, POE/SBS modified asphalt, and its residue after short-term and long-term aging performance testing were investigate. The results indicated that POE can be compatibilized with the SBS modified asphalt due to its good molecular mobility. In this way, the SBS can be dispersed more homogeneously and be swollen more effectively, through which the aging process is reduced in this compatibility system.
