Influence of Modify Bituminous Mix with Fly Ash

Abstract

In India, the disposal of industrial waste streams like fly ash and waste tires from vehicles constitutes a significant environmental challenge. Fly ash, generated predominantly by coal-fired power stations, exceeds 0.3 billion tons annually and is a major solid waste byproduct. Concurrently, the rising popularity of automobiles, including four-wheelers and two-wheelers, has led to an increase in discarded tires. A substantial portion—approximately 60%—of these waste tires are disposed of through informal routes, both in urban and rural regions, resulting in pollution issues such as air contamination from open burning and aesthetic degradation. To address these concerns, effective utilization of these waste materials through technological innovation is essential. Developing modified bituminous mixtures that are resilient, durable, and environmentally friendly is a promising approach. Such mixtures should resist fatigue and permanent deformation while remaining cost-effective. To optimize these properties, various tests are conducted on different material combinations to identify the most suitable mix. This study employs the Marshal method for designing bituminous mixes with varying fly ash percentages, aiming to evaluate the resulting properties.
