This work presents a laboratory study conducted to evaluate the potential impacts of different graphene oxide (GO) dosages on properties of non-modified binder and SBS modified binder. The effects of GO on viscosity, rheological properties, creep and recovery behavior, cracking resistance, and thermal properties of unaged/RTFO aged binders were characterized respectively. It was demonstrated that the addition of trace amounts of GO (no more than 0.2 wt%) enhanced the paving temperature (120-135 degrees C) viscosity, high-temperature elasticity and rutting resistance of non-modified/SBS modifie...
