摘　　要：选用高温、中温、低温性能较优的Ba hrain(巴林)沥青作为改性沥青的原料沥青,采用SBS、GN-1及GN-2改性剂进行复合,制备了PG 75-16、PG 75-22、PG82-16、PG 82-22四个系列改性沥青产品,优化配方,降低成本,其技术方案在中东地区应用具有较好的经济性。The properties of four kinds of Middle East asphalt were evaluated including conventional per- formance and PG classification. As Bahrain asphalt had good performance at high, medium and low tempera- ture, it was selected as raw material of modified asphalt. By adding modifier SBS, GN - 1 and GN - 2, four series of modified asphalt products had been prepared , they were PG 76 - 16, PG 76 -22, PG 82 - 16 and PG 82 -22. Through optimizing formula and minimizing cost, this technical proposal had good economy appli- cation in the Middle East.
