The escalating demand for sustainable infrastructure has generated significant interest in the development of eco-friendly pavements incorporating waste materials. Traditional pavements depend heavily on virgin aggregates and bitumen, depleting natural resources and contributing to environmental degradation. This research article explores innovative pavement designs using industrial, agricultural, and municipal waste by-products—including recycled concrete aggregate (RCA), fly ash, waste plastic, crumb rubber, slag, and rice husk ash—to improve performance while mitigating environmental impact. A systematic methodology is proposed to evaluate material properties, mixture design, structural behavior, and life-cycle environmental benefits. Laboratory and field implementation results indicate that sustainable pavement mixtures can achieve comparable or improved mechanical properties, enhanced durability, and lower carbon footprint relative to conventional designs. The study also presents recommended mix design frameworks, performance evaluation methods, and guidelines for implementation in real-world scenarios. Eco-friendly pavement systems have been validated through performance testing and life-cycle assessment (LCA), demonstrating reduced greenhouse gas emissions and lower reliance on virgin materials. The findings underscore the feasibility and benefits of integrating waste materials in pavement engineering, offering valuable insights for researchers, policymakers, and practitioners in sustainable infrastructure The integration of these waste materials not only addresses environmental concerns but also offers economic advantages by reducing construction costs. Challenges such as material variability, long-term performance, and regulatory acceptance are discussed to provide a comprehensive understanding of sustainable pavement implementation. Future research directions emphasize optimizing mix designs and expanding field trials to further validate these innovative solutions.development.
