A THEORETICAL REVIEW ON THE ROLE OF NATURAL FIBRES IN SUSTAINABLE PAVEMENT SUBGRADE STABILIZATION

Loknath Panigrahi, Dr. Ramprasad Naik & Dr. Jayesh A. Shah

The rapid deterioration of pavements built over soft soils is a persistent challenge in road construction, often resulting in high maintenance costs and reduced service life. Traditional methods of improving weak subgrade soils include chemical stabilization using lime, cement, or other additives. However, these methods raise environmental concerns due to their high carbon footprint. In recent years, the use of natural fibres as a sustainable solution for subgrade stabilization has gained attention. Natural fibres such as coir, jute, sisal, and bamboo offer numerous advantages, including biodegradability, low cost, and the ability to reduce shrinkage and desiccation cracks in soil. This paper presents a comprehensive theoretical review of natural fibre-based soil stabilization techniques, focusing on their role in enhancing soil strength and reducing pavement deterioration. The study explores the mechanical properties of various natural fibres and their interactions with different soil types. It also examines key factors affecting fibre performance, such as fibre length, dosage, orientation, and degradation over time. Additionally, this paper addresses the sustainability benefits and limitations of using natural fibres in pavement construction, with an emphasis on future research directions and practical applications in road infrastructure. The findings from this theoretical review suggest that natural fibre stabilization can be an effective, eco-friendly approach to improve pavement performance, especially in regions with abundant natural fibre resources. By promoting sustainable construction practices, the use of natural fibres can help reduce the environmental impact of road projects and contribute to achieving global sustainability goals in the construction sector.
