Abstract：A graphene asphalt concrete with excellent electrothermal properties was prepared by using graphene doped with graphene and conductive composite fibers as conductive phase materials.Firstly，the ratio of graphene asphalt concrete was optimized，and then the road performance and electric thermal performance of graphene asphalt concrete were analyzed. The test results showed that when the fiber length was 7mm ，the fiber content was 0.4% ， and the graphene content was 3% ，the resistivity of graphene asphalt concrete was about 20Ω·m ，the dynamic stability was 1 634.9 times/ mm ，the indirect tensile strength was 4.772MPa ，the residual stability of the immersed Marshall residue was 91.4% ，thefreeze-thaw fatigue residual strength was 77.4% ，thecumulative indirect tensile deformation was 12.374mm ，and the number of fatigue loads was 41 314 times，showing good electrical conductivity and road performance. Under the voltage conditions of 36，72 and 108V ，the surface temperature of graphene asphalt concrete slabs was raised to 0℃for less than ，showing good electrothermal performance Key words ：graphene ；modified asphalt ； melting snow and ice ；electric heating performance
