采用差示扫描量热分析（DSC）和热失重分析（TGA）方法，通过室内试验对比研究了 SBS 和 Sasobit改性剂与基质沥青的相容性以及3种沥青结合料的玻璃化转变和热稳定性。结果表明，SBS 和 Sasobit 与基质沥青均可良好相容。3种沥青结合料的热分解趋势相同，组分降解均为一次完成，改性沥青的高温稳定性优于基质沥青，其中 SBS 改性沥青最优。

The DSC and TGA methods have been adopted to compare and study the compatibility, glass transition and thermostability between matrix asphalt,SBS modified asphalt and Sasobit warm mix asphalt binders.The results show that SBS and Sasobit have good compatibility with matrix asphalt.These 3 asphalt binders have the same thermal decomposition trends,and all the components of degradation for one time.The high-temperature stability of modified asphalts is superior to matrix asphalt,and the SBS modified asphalt is the best among them.
