| 摘 要： | 以动态剪切流变仪（dynamic shear rheometer）实测的玻璃化转变温度（Tg）为评价指标，针对同一种油源、不同标号的基质沥青，分析了改性剂结构和掺量对苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）改性沥青低温性能的影响．结果表明，改性剂结构对SBS改性沥青的低温性能影响不大；而改性剂掺量对SBS改性沥青的低温性能有重要影响，这种影响受到基质沥青标号的限制，基质沥青的标号越大，掺量对低温性能的影响越大．

| Abstract: | The influence of the structure and content of modifier on the low temperature performance of SBS(styrene-butadiene-styrene) modified asphalts which consist of the same source but different grades of imported asphalt is analyzed,with the glass transition temperature(T_g) that is tested by dynamic shear rheometer as evaluation index.The result indicates that the structure of modifier has little influence on the low temperature performance of SBS modified asphalts,but the content of the modifier has a great influence which is confined by the grade of base asphalt.The higher the grade is,the greater the influence is. |

| Keywords: | styrene-butadiene-styrence modified asphalt low temperature performance structure of modifier content of modifier glass transition temperature |
