| Abstract: | The relationship between PI and the average molecular weight about asphalt was stud ied. Based on the results of PI and the average molecular weight research, we put forward the approach to increase PI of high-grade paving asphalt through selecting crude oil, improving vacuum dis tillation separating effect , oxidizing and crude oil blending. The test result of crude oil selecting indi-cates that crude oil 2 to produce grade-A product. The test result of oxidation proves that with appropriate oxidizing process Saudi middle vacuum residue can be used to produce grade-A product. The test of improving vacuum distillation separating effect proves that Saudi middle crude oil can be used to produce gradc-A product, which has been verified in a commercial vacuum distillation unit. |
