摘　　要：为了考察颗粒SBR用于沥青改性剂的可行性,通过调合与改性工艺,研究了颗粒SBR用作道路沥青增延剂和改性沥青改性剂的改性效果。结果表明,通过适宜的工艺条件,颗粒SBR作为增延剂制备的塔河原油道路沥青以及作为改性剂制备的改性沥青性质均符合JTG F40—2004指标的要求,而且闪点较高,其它性质与市售块胶制备的沥青相当。该颗粒SBR既可作为生产塔河原油等沥青的增延剂使用,也可用作生产SBR改性沥青的改性剂使用。对用于生产沥青而言,具有工艺简单、使用方便的优点。In order to investigate feasibility of particulate SBR used as asphalt modifier, the modified effect of particulate SBR used as improving properties agent of paving asphalt and modified asphalt was stud- ied. The results showed that through appropriate process, the quality level of Tahe oil paving asphalt and mod- ified asphalt were improved by particulate SBR and met the standard of JTG F40 - 2004. Compared with the asphalt prepared by commercial lump SBR, the flash point was higher. The particulate SBR could be used as not only improved agent, but also modifier. The advantage of particulate SBR was simple process and convert-ient use.
