摘　　要：以锦西石化分公司生产的辽河减压渣油为基质沥青,SBS为改性剂,采用适当的助溶剂,试制SBS改性道路沥青。相容剂对改性沥青的针入度、低温延度、软化点均有较大影响,选择合适的助溶剂添加粮是非常必要的。The SBS modified asphalt was prepared by using SBS modifier and proper additional solvent, the vacuum residue of Liaohe oil produced in Jinxi petrochemical company was selected as the matrix asphalt. The additional solvent can greatly affect properties of the modified asphalt, such as the penetration index, the softening point and the low tempera- ture ductility. It is necessary to choose a proper additional solvent.

关 键 词：辽河减压渣油 SBS助溶剂 改性沥青
