dc.description.abstractThis research presents the laboratory outcomes in which the influence of pongamia oil, a locally available non-edible oil as rejuvenator on the performance of hot mix asphalt containing reclaimed asphalt pavement was assessed. A research study has been taken up in three stages to assess the potential of rejuvenator. First stage focussed on determining optimum dosage of rejuvenator. The aged binder was then mixed with the rejuvenator at varying rates and the rheological properties were studied in terms of rutting, and fatigue using Dynamic Shear Rheometer. Second stage, thermal stability of the binder determined with the help of Thermo gravimetric analysis, which shows binder samples are stable up to 230��C. From the results, it was concluded that 5% of pongamia oil can successfully rejuvenate the aged binder. Third stage, performance of HMA prepared with varying RAP content (30%, 40%, 50%, 60% and 70%) rejuvenated with Pongamia oil and control mixture was assessed according to superpave mix design guidelines. The performances of the rejuvenated HMAs were evaluated in terms of volumetric properties, indirect tensile strength, rutting and fatigue parameters. By comparing rejuvenated mixtures, 60% rejuvenated RAP mixture performs were found to perform superior than the control mix. � 2020, Springer Nature Switzerland AG.en_US
