【摘要】 以70号沥青、减压渣油和催化裂化油浆为原料,配制沥青原料、制备油浆改质沥青和SBS改性油浆改质沥青,分析其性质和族组成,探讨了油浆改质沥青性质对SBS改性沥青性质的影响,并结合荧光显微照片,考察了SBS在油浆改质沥青中的分散状态和微观结构。结果表明:芳香分含量较高时,油浆改质沥青的性能较好,SBS与其相容性也较好,从而能够制备出性能较好的SBS改性油浆改质沥青;SBS改性缩合油浆改质沥青的性质优于SBS改性油浆改质沥青的性质,且达到了SBS改性沥青I-D级标准。更多还原

【Abstract】 By analyzing the properties and SARA composition of the raw materials and the asphalt blending with FCC slurry,the influence of the properties of the blending asphalt on the performance of its SBS modified asphalt was discussed.Meanwhile,the dispersion and microstructure of SBS in the blending asphalt were investigated by fluorescence micrograph.The results demonstrated that high content of aromatic contributes to the better performance of the asphalt blending with FCC slurry and compatibility between SBS and asphalt with FCC slurry,which enhance the performance of SBS modified asphalt with FCC slurry.Moreover,the properties of SBS modified asphalt with condensed FCC slurry was superior to those of SBS modified asphalt with FCC slurry and satisfy the requirement of I-D grand standard of SBS modified asphalt.更多还原
