摘　　要：分别对SBS改性沥青胶结料添加EvothermTM-DAT温拌剂前、后的性能进行试验研究,通过性能试验发现,基于表面活性剂EvothermTM的SBS温拌沥青胶结料的低温性能同SBS改性沥青相差不大,高温性能要优于SBS改性沥青,温拌剂的加入并没有降低原样SBS改性沥青的性能等级。The performances of SBS modified asphalt are tested and studied which is expected to add EvothermTM-DAT or not.Through the performance tests found that the low-temperature properties of warm SBS modified asphalt based on EvothermTM surfactant process does not differ large from SBS modified asphalt,high-temperature performance is better than SBS modified asphalt,the addition of EvothermTM Surfactant does not reduce the performance grade of SBS modified asphalt.
