采用BBR和DSR流变仪测定了改性沥青的流变数据。采用相同的SBS对同一种沥青进行不同掺量的改性。研究了SBS改性沥青的流变性能与SBS掺量的关系。指出随着改性剂掺量的增加，改性沥青的高低温性能得到改善。结果表明，改性沥青的性能在很大程度上受其亚显微结构的影响。表2，参考文献8。
This paper measured the rheological date of modified asphalt by BBR and DSR rheologic instrument. The same asphalt was modified by the same SBS with different dosage. The relationship of rheological date and SBS dosage with modified asphalt was studied. It was pointed that the properties of modified asphalt at high and low temperature are improved by the content of modifier increasing. The results indicate that the properties of modified asphalt are affected by its sub-microstructure to a great extent. 2 tabs, 8 refs.
