Thermo rheological performance of DFNS enhanced asphalt binder modified with waste cooking oil and waste rubber powder (opens in new tab)

This study investigates the combined effects of dendritic fibrous nanosilica (DFNS), waste cooking oil (WCO), and waste rubber powder (WRP) as multifunctional modifiers for asphalt binders. Seven asphalt formulations were prepared and evaluated through conventional tests, dynamic shear rheometry (DSR), bending beam rheometry (BBR), fatigue time sweep analysis, and thermal characterization. Results showed that the DFNS/WCO/WRP modified binder exhibited improved rheological and mechanical perfo...
