摘　　要：以塔河原油生产的70号沥青为基质沥青,通过对不同改性剂、稳定剂和相容剂等的研究,筛选出制取改性沥青的方案,并在工业装置上生产出满足JTG F40—2004要求的SBSⅠ-C改性沥青。该SBSⅠ-C改性沥青产品性能分级为PG76-28,具有软化点高、针入度指数高和抗老化性能好等优点,塔河原油SBSⅠ-C改性沥青混合料的高温性能、低温性能和水稳定性等主要指标均满足交通部JTG F40—2004要求。Using 70# asphalt of Tahe crude oil as basic material, the solution for preparation of SBS modified asphalt was determined by performance evaluation of modified asphalt with different modifier, stabilizer and compatilizer in laboratory screening tests. The industrial practice was conducted based on the laboratory solution. The qualities of the produced SBS modified asphalt meet the SBS I-C require- ment of JTG F40--2004 standard. The product has advantages of higher softening point and penetration index, and better anti-aging performance, being the PG78-28 grade. The rutting tests indicate that the SBS modified asphalt mixture has a better performance both at high temperature and low temperature, and good water stability, meeting JTG F40-2004 requirement.
