Abstract: By analyzing the properties and SARA 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.
