| 摘 要： | SBS改性沥青在使用过程中，经受热、氧、光及交通荷载等因素的交互作用，其路用性能随之劣化，研究其老化行为具有重要意义。本文分析了SBS改性沥青老化过程中的影响因素，阐述了沥青老化性能评价指标与方法，综述了SBS改性沥青热-氧、热-光-氧老化机理，表明SBS改性沥青老化过程伴随沥青的老化和SBS的降解，轻组分向重组分转变；改善SBS的聚合结构、掺入纳米复合材料等稳定剂是延缓SBS改性沥青老化的有效途径。 |

| Abstract: | During the service of SBS modified asphalt, which is affected by interactions with heat, oxygen, light and traffic load, its road performance is degraded. Therefore, investigating its aging behavior is significant. This paper analyzes the influence factors of SBS modified asphalt aging, elaborates the evaluation indexes and methods of asphalt aging, and summarizes the thermo-oxidation aging mechanism and thermo-photo-oxidation aging mechanism for SBS modified asphalt. The results indicate that during the aging of SBS modified asphalt, asphalt components are aging themselves, meanwhile SBS is degraded, including transformation of light components into heavy components. Furthermore, improving the polymeric structure of SBS or blending stabilizers such as nanocomposites can effectively delay aging of SBS modified asphalt. |
