The study of producing heavy traffic asphalt by using the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field

The characteristics of the high viscous crude from No.1 Shuguang Zone of Li aohe Oil Field are similar to those of residue distillates of general crude such as high density(p(20)=0.9977 g.cm(-3))(,)high viscidity (v(100)=1223. 9 mm(2).s(-1)) and high carbon/hydrogen ratio. This oil contains less wax, but rich in resin and asphalt, which belongs to low sulfur naphthene-base c rude oil and can be used as feedstock to produce high paving asphalt. But n ow it is used as fuel after emulsificating. In order to make full use of th is oil and resolve the problem of paving asphalt demand-supply, various pav ing asphalts conforming to GB5009296 standard were produced by blending vac uum residue of the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field and waste oil which is rich in aromatics and poor in wax. The labora tory test results show that modified paving asphalts have good low-temperat ure properties and antiaging feature.
