In order to improve the rheological properties of rubber modified asphalt, the feasibility of graphene rubber composite modified asphalt was studied. Dynamic shear rheological(DSR) test combined with electrodynamic fluorescence microscopy(E FM) and Fourier transform infrared spectrometer(FTIR) was used to study the macro mechanical properties of graphene rubber modified asphalt with different content of graphene, FTIR was used to investigate the change of the microstructure of rubber modified asphalt. The results show that the addition of graphene can improve the elastic recovery and deformation resistance of rubber modified asphalt, and improve its rheological properties. The fluorescence microscopy of graphene rubber composite modified asphalt shows uniform distribution and continuous morphology in the electro fluorescence microscope, which indicates that the storage stability of rubber modified asphalt is improved. In infrared spectroscopy, the addition of graphene makes rubber and asphalt more compatible. The relative increase of CC content indicates that its mechanical properties are improved.
