“…A substantial reduction in emissions after the use of WMA technologies has also been reported, thus improving the working conditions ( 10 ). Besides being cost-effective and environment-friendly, WMA additives have shown improvements in the rheological performance of asphalt binders and in the thermo-mechanical properties of asphalt mixes ( 11 – 13 ).…”

The current study investigates the synergized effect of a nanomaterial and two warm mix additives asphalt (WMA) additives on different properties of asphalt binders. The study used an optimal percentage of 2% for nano-Al2O3; two WMA additives were used in different concentrations. The results revealed that the addition of WMA additives increased the softening point of nano-Al2O3 modified asphalt binder. Penetration and ductility results showed a decrease after the introduction of WMA additives. The viscosity of nano-Al2O3 modified asphalt binders showed a reduction after the introduction of WMA additives. Rutting evaluation was done by using the superpave rutting parameter and multiple stress creep and recovery (MSCR) test. The fatigue performance of the asphalt binders was measured using the superpave fatigue parameter and linear amplitude sweep (LAS) test. Results showed that the introduction of WMA additives improved the rutting and fatigue performance of nano-Al2O3 modified asphalt binders. The introduction of WMA additives enhanced the aging performance of the nano-Al2O3 modified asphalt binders.
