The low flash point of Tahe vacuum residue affects its derivative asphalt product quality. Thus improving the Tahe vacuum residue flash point is beneficial to the asphalt product quality and to the capacity of the plant. Based on the analysis and comparison of Tahe crude with Kuwait crude, a conclusion could be drawn that the reason for low flash point of Tahe vacuum residue is due to high content of asphaltene in the crude. By blending FCC slurry in Tahe crude oil and intensifying vacuum distillation, the Tahe vacuum residue flash point can be significantly improved. Blending 1% FCC slurry make the vacuum residue flash point increase by 1.6��C. A high quality road asphalt product can be manufactured using such residue with SBR.

By special chemical crosslinking additive or styrene-butadiene rubber latex admixing process,SBR modified asphalt producted from Tahe crude oil feed was developed to meet the JTG F40-2004 polymer modification technique requirements of Transport of People's Republic of China.Accommodation of main process conditions with the grade of modified asphalt is investigated,their toughness and tenacity performance are effectively improved by adding special chemical crosslinking.According to the U.S.SHRP PG specification and grade specification of Ministry of Transport of People's Republic of China,the performance of SBR modified asphalt obtained from Tahe oil by industrial production process and their mixes was evaluated, the result shows that Tahe oil SBR modified asphalt's performance can meet the PG76-28 binder grade level and suitable to all climatic conditions categories,forthermore,has good high temperature performance、improved water damage resistance and well anti-fatigue-cracking performance.
