Techno- Engineering Innovations: Integrating Geosynthetics and Construction & Demolition Waste for Base Soil Stabilization in Flexible Pavements

The research explores two key approaches to enhance the properties of base soil in flexible pavement construction. Firstly, it investigates the effectiveness of incorporating geosynthetic materials to boost the strength and stiffness of the subbase layer. Field and laboratory tests demonstrate the potential of geosynthetics to increase pavement strength, thereby extending its lifespan. Secondly, the study examines the viability of using recycled construction and demolition waste (RCDW) aggregates as sustainable alternatives to traditional natural aggregates. Extensive testing reveals that properly compacted RCDW aggregates improve bearing capacity, resilient modulus, and resistance to permanent deformation, making them suitable for base and sub-base layers. These approaches offer promising solutions to improve the properties of base soil, enhance pavement performance, and promote sustainable construction practices.
