Thermo rheological performance of DFNS enhanced asphalt binder modified with waste cooking oil and waste rubber powder

This study delves into the combined effects of dendritic fibrous nanosilica (DFNS), waste cooking oil (WCO), and waste rubber powder (WRP) as multifunctional modifiers for asphalt binder. The incorporation of these waste materials aims to enhance the thermo-rheological performance of the asphalt binder, which is crucial for ensuring the durability and longevity of roads. The researchers employed a comprehensive experimental approach, incorporating various characterization techniques to evaluate the modified asphalt binder's properties. The results demonstrate the synergistic effects of the combined modifiers, leading to improved high-temperature stability, low-temperature flexibility, and resistance to deformation. This study's findings have significant implications for the development of sustainable and eco-friendly asphalt binder modification techniques, which can contribute to reducing waste disposal issues and minimizing the environmental impact of road construction and maintenance.
