摘　　要：采用扫描电镜观察了常用的沥青改性剂SBS和SBR在基质沥青中的分散状态,同时比较了这两种改性沥青的差热扫描图谱。通过对比改性沥青的微观形貌,并结合热稳定性分析,深入探讨了常用沥青改性剂SBS和SBR对沥青的改性机理。To observe dispersed state of modifiers SBS and SBR in matrix asphalt with scanning electron microscope, simultaneously to contrast differential scanning calorimetry （ DSC ） of two kinds of modified asphalt. By contrast to microstructures of observed modified asphalt and to its thermal stability, the modified mechanisms of SBS and SBR towards the asphalt are thoroughly approached further.
