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。
DOA coming from pilot solvent deasphalting were modified by using pilot resins and rich - aromatic FCC slurry. The influence of the amount of modifier added on asphalt's properties was discussed,qualified No. 60A paving asphalt was obtained after modification of pilot DOA.
