Performance of Aged Asphalt Binder Treated with Various Types of Rejuvenators

High demand for asphalt binders in road construction verifies the need of finding alternative materials through pavement recycling. This paper investigated impact different rejuvenators on performance an aged binder. Virgin Olive oil, virgin cooking waste engine and oil were added to a 30/40 penetration grade binder at fixed content 4% all types. The wet method was used blend physical, rheological, chemical properties rejuvenated evaluated using several laboratory tests which include penetration, softening point, bleeding, loss heating, storage stability, index, ductility, viscosity, dynamic shear rheometer, Fourier transform infrared spectroscopy. outcomes physical showed that olive, waste, can restore 60/70. In contrast, required more quantity rejuvenate A sufficient amount rejuvenator could regenerate (G*/sin δ), (δ°), (G*) addition olive oils led rutting issue. No reactions observed with but they give reducing oxidation level As result, further research should be performed given it is inexpensive provides excellent results.
