Abstract

The construction sector is confronted with growing difficulties in procuring sustainable materials for highway building while simultaneously reducing environmental effect. This study provides a thorough examination of the research carried out on the utilise of by-products and industrial wastes in the building of highways. By-products and industrial wastes, such as fly ash, slag, foundry sand, and similar materials, have the potential to be utilised as alternative building materials. This may provide economic, environmental, and performance advantages.The study analyses many research that investigate the engineering qualities, performance characteristics, and environmental consequences of using by-products and industrial wastes in the building materials for highways. The research results emphasise the capacity of these materials to improve the mechanical characteristics, longevity, and ecological viability of roadway infrastructure. In addition, the utilise of by-products and industrial wastes helps to minimise waste, save resources, and reduce carbon footprint. The study focutilises on many important subjects, such as the utilise of fly ash and slag in asphalt concrete and concrete mixes, the integration of waste foundry sand in road foundation and subbase layers, and the implementation of other industrial by-products in soil stabilisation and pavement building. Moreover, the paper examines the difficulties, restrictions, and potential areas of future investigation in the utilise of by-products and industrial wastes for the purpose of constructing highways.This research highlights the significance of investigating creative approaches for constructing environmentally-friendly highways by efficiently using by-products and industrial trash. Adopting these methods may result in substantial progress in the long-term durability of infrastructure, the effective utilise of resources, and the responsible management of the environment in the transportation industry.Key Words: By-products, Industrial Wastes, Highway Construction, Sustainable Materials, Recycling, Utilization, Waste Management, Pavement Materials
