Preparation And Performance Characteristics Of Reduced Graphene Oxide Modified Asphalt

Reduced graphene oxide (RGO) was self-prepared by the oxidation reduction method and then characterized by several tests known as Fourier Transform Infrared Spectroscopy (FTIR) test, scanning electron microscopy (SEM) test, transmission electron microscopy (TEM) test, elemental analysis, raman measurement and thermogravimetry (TG) analysis to evaluate the properties of RGO. Additionally, RGO modified asphalt was prepared in this research to study the influence of RGO on matrix asphalt. Some of the normal performances of RGO modified asphalt were studied in terms of penetration at medium temperature, penetration index (PI), softening point, equivalent softening point T-800 at high temperature and ductility at low temperature. Results showed that the prepared RGO has obvious layer structures and good properties and the performance of RGO modified asphalt at high temperature has increased significantly while the performance at low temperature decreased slightly. This research can provide an insight for the further study of RGO modified asphalt to enhance its road performance.
