红浅003稠油研制道路沥青

Development of Paving Asphalt with Hong-qian 003 Heavy Oil

以红浅003稠油为原料,分别采用蒸馏和丙烷脱沥青-调和工艺考察了研制道路沥青的可行性,研究表明两种工艺均可以研制出满足JTG F40—2004规范要求的50号、70号和90号A级道路沥青,道路沥青的性质和路用性能分级均与低凝稠油沥青相当。

The technologies such as distillation and propane deasphalting-blending were adopted respectively to examine the feasibility of developing road asphalt. The studies showed that A-class road asphalt such as No. 50, No. 70 and No. 90, which met JTG F40 - 2004 specifications could be developed by the two processes, and the properties and road performance grade were equal to low freezing heavy crude bitumen.
