摘要
介绍了国内外沥青包括基质和聚合物改性沥青老化性能的研究方法,涉及沥青宏观层次(力学、流变及组分等)和微观层次(波谱分析及显微技术等)上各技术的应用,并比较了各研究方法的优缺点,综述了沥青的老化机理。
The research methods at home and abroad on the aging properties of asphalt including base and polymer- modified asphalt were presented in the paper. It includes the application of techniques covered macro-level （mechanics, rheology and chemical characteristics） and micro-level （spectrum analysis and microscopic techniques）. The disadvantages and advantages of all the techniques were compared. The aging mechanisms of asphalts were synthesized.
