In this paper, bio-binders were used as a bitumen extender to acquire a green, eco-friendly alternate binder (GAB). To achieve this objective, an extensive investigation of the flow properties (dynamic and rheological) for the prepared green alternative binders (GAB) which was obtained by mixing a conventional 60/70 bitumen with different Green binder additives (GBA) - that was formed from waste cooking oil and waste polymers under different conditions- this mixing have been done as 1:1 volume ratio. For this reason, a number of tests were carried out, including standard physical attributes, Dynamic viscosity at different (time, temperature and shear rate) and Dynamic shear rate (DSR) test. The results obtained from this research, show that the prepared GAB samples enhanced the rheological and physical characteristics of asphalt samples and the sample with formula (L+ GBA3) could be considered as the most promising mixture can be used for paving, as it has the highest rutting factor value with the same physical and rheological properties for the original asphalt sample.
