对中试溶剂脱沥青DOA采用中试胶质以及富含芳烃的FCC油浆进行改质,探讨了改质剂加入量对沥青性质的影响,制备出合格的60号甲道路沥青。
The pilot plant deasphalting DOA was modified with pilot-scale gelatin and aromatics-enriched FCC slurries. The influence of the amount of modifier on the properties of the bitumen was discussed, and a qualified No. 60 alpha road asphalt was prepared.
