Abstract

The production of Hot Mix Asphalt (HMA) requires high energy input and releases substantial amounts of greenhouse gases and other hazardous emissions, contributing significantly to air pollution. Warm Mix Asphalt (WMA) offers a more sustainable alternative, as it requires lower mixing and production temperatures, thereby reducing both energy consumption and emissions. This study investigates the potential of waste motor engine oil (WMEO) as a bitumen modifier in WMA. WMEO was incorporated at varying dosages of 0%, 3%, 4%, and 5% by weight of bitumen. The modified binders and mixtures were evaluated through penetration, softening point, stability, flow, and stiffness tests. The results demonstrated that WMEO significantly enhanced penetration and softening point values, while also improving mixture performance in terms of stability, flow, and stiffness. These findings suggest that WMEO can serve as an effective modifier for WMA, contributing to improved performance and sustainability in asphalt pavement applications.
