- Lateritic soils extensively found in the Ranchi district of Ranchi are widely used as subgrade material in rural and semi-urban infrastructure projects. However, these soils often exhibit moderate to high plasticity, low bearing capacity, and significant moisture susceptibility, leading to premature pavement distress and foundation settlement. Considering the rapid infrastructural development in the Ranchi region, there is a need for sustainable and cost-effective soil improvement techniques. This study investigates the stabilization of locally sourced lateritic soil from Ranchi using lime and fly ash blends. Laboratory experiments were conducted by incorporating varying percentages of lime (2–8%) and fly ash (5–20%) into the natural soil. Engineering properties were evaluated through Atterberg limits, Standard Proctor compaction, Unconfined Compressive Strength (UCS), and California Bearing Ratio (CBR) tests. The results demonstrate a considerable reduction in plasticity index and improvement in strength and load-bearing capacity with the addition of stabilizers. The combined lime–fly ash treatment showed enhanced performance compared to individual additives. The findings indicate that lime–fly ash stabilization is an effective and sustainable ground improvement technique suitable for road subgrades and light foundation works in the Ranchi region, promoting the utilization of industrial by-products and supporting sustainable infrastructure development in Jharkhand.
