摘要：Graphene oxide nanomaterials are increasingly used in various fields due to their superior *** order to study the influence of graphene oxide additives on the performance of modified asphalt,in this study,graphene oxide modified asphalt was prepared and characteristics was studied including the high deformation resistance performance and the self-healing property of modified *** groups and morphology of graphene oxide modified asphalt were described by Fourier transform infrared *** high deformation resistance performance and self-healing effect of asphalt samples were obtained through dynamic slear rheometer(DSR)*** shows that graphene oxide dispersions improve the performance of asphalt relatively well compared to graphene oxide *** is no chemical reaction between graphene oxide and asphalt,but physical *** addition of graphene oxide improved the high deformation resistance of modified asphalt and expedited the self-healing ability of asphalt under fatigue load.
