文摘In this paper morphology of APP modified bitumen (APP MB) and SBS modified bitumen (SBS MB) was studied by scanning elecron microscopy (SEM) and the morphology property relationship of these two modified bitumen (MB) was discussed. The results indicate that the APP MB systems is in a homogeneous phase structure and the SBS MB system is in a heterogeneous phase structure. Improvement of bituminous physical properties by APP and SBS is closely related with the microstructure of APP and SBS MB.
