Dynamic Rheological Behavior of Green Alternative Binder for Asphalt 60/70 at Different Temperatures

An alternative approach for decreasing the demand and dependency for crude petroleum/bitumen binders is the use of bio-binders. In this paper, bio-binders were used as a bitumen extender to obtain an eco-friendly green alternative 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. A series of tests were conducted for such purpose, including conventional physical properties, 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 improved the physical and rheological properties of asphalt samples and the sample with formula (L+ GBA(3)) 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.
