Abstract

Employing Hot Mix Asphalt (HMA) technology for asphalt pavement construction results in the emission of greenhouse gases and other harmful pollutants, contributing to significant air pollution due to extensive energy consumption. Consequently, the adoption of Warm Mix Asphalt (WMA) is recommended, given its potential for enhanced energy efficiency and reduced emissions due to lower mixing and production temperatures compared to HMA. This research delves into the impact of incorporating waste motor engine oil (WMEO) as a bitumen modifier in warm mix asphalt. The investigation involved adding WMEO at various percentages, specifically 0%, 3%, 4%, and 5% based on the weight of bitumen. The study assessed the performance of the samples in terms of penetration, softening point, stability, flow, and stiffness. The findings revealed that the incorporation of WMEO in warm mix asphalt led to a substantial improvement in penetration and softening point. Moreover, the results indicated that incorporating WMEO as a bitumen modifier could enhance the performance of WMA in terms of stability, flow, and stiffness.

Abstract

Waste management is increasingly crucial worldwide, and integrating agro-waste into pavement construction offers a promising approach for sustainability and enhanced material properties. This research investigates the use of wood ash as a filler in asphalt mixtures, using varying proportions of 0%, 2%, 4%, and 6% replacement by weight of asphalt. Experimental tests, including softening point, penetration, Marshall stability and flow, indirect tensile strength, and abrasion loss, were conducted to assess the influence of wood ash on asphalt mixture properties. The findings reveal that wood ash can improve certain performance aspects such as stiffness and density at an optimal content of 4%, balancing tensile strength and flow properties. However, higher wood ash percentages negatively affected the mixture's overall durability and stability. These results underscore the importance of optimizing wood ash content to enhance asphalt performance. This study demonstrates that wood ash is a sustainable alternative to conventional fillers in asphalt production, contributing to environmental conservation and waste management. Further research is recommended to explore various aggregate gradations, binder types, and the potential of wood ash as an asphalt modifier for quality improvement. Such studies are vital for advancing pavement technology, improving infrastructure quality, and addressing environmental challenges.
