摘　　要：将一种反应性助剂用于改善SBS改性沥青的粘结性能。研究了谈反应性助剂对 SBS改性沥青常规物理性能和粘结性能的影响。结果表明:反应性助剂的加入,明显地提高了 SBS改性沥青的软化点、低温延度和弹性恢复率,显著增加了SBS改性沥青对钢板的粘结强 度,所制备的SBS改性沥青具有优良的粘结性能。A kind of reactive assistants was used to improve the adhesive properties of SBS modified asphalt. The influence of the reactive assistants on the physics properties and the adhesive properties of the SBS modified asphalt was investigated. The results indicated that adhesive strength of the SBS modified asphalt to steel was remarkably increased and softening point, low temperature ductility and elastic recovery rate were greatly improved after adding the reactive assistants.
