摘要
以中东进口原油的减渣为原料，经溶剂脱沥青得到脱油沥青，并将其作为基本组分与改性油浆等富含芳烃的组分调合，生产符合ＧＢ／Ｔ１５１８０－９４的高等级道路沥青，并且薄膜烘箱试验后的１５℃延度大于１００ｃｍ，其质量与进口沥青相当。
Deoiled asphalt (DOA)obtained by solvent deasphalting(SDA)vacuum residue(VR)of Middle East crude oil,is mixed with some blending components such as modified FCC slurry oil,results in producing high grade paving asphalts,which meet GB/T 15180-94 specifications and ductility(15℃) of TFOT residue exceeds 100 cm The quality of asphalt product is similar to that of foreign paving asphalts
