A hot mix asphalt binder (HMAB), PG 64-22 with 0.05 wt.% graphene oxide (GO), was used to prepare warm mix asphalt binders (WMABs) with three types of warm mix additives, i.e, 3 wt.% Sasobit, 5 wt.% waste cooking oil (WCO), and Sasobit + WCO. The viscosity-temperature performance, rheological performance, low-temperature cracking behavior, Fourier Transform infrared spectroscopy (FTIR) spectrum, and low-temperature thermal properties of various HMABs and WMABs were investigated in the laboratory. The experimental results revealed that GO remark...
