        abstract = {Expansive soils, known for their high swelling and shrinkage potential, present serious challenges to the stability and durability of civil engineering structures. Conventional stabilization techniques, while effective, often rely on materials that are costly and environmentally taxing. This study explores the use of dry leaf ash (DLA) and sea shell powder (SSP)—two abundant and sustainable waste materials—as alternative stabilizers for expansive soils. The soil was treated with varying proportions of DLA and SSP, both individually and in combination, and subjected to a series of geotechnical tests, including Atterberg limits, compaction characteristics, free swell index, unconfined compressive strength (UCS), and California Bearing Ratio (CBR). The results demonstrated a significant improvement in engineering properties, including reduced plasticity and swelling behaviour, along with enhanced strength and load-bearing capacity. These improvements are attributed to pozzolanic reactions and the filler effect, where reactive silica from DLA and calcium carbonate from SSP form cementitious compounds that improve the soil matrix. The findings suggest that the combined use of DLA and SSP is a viable, eco-friendly solution for the stabilization of expansive soils, offering both performance efficiency and environmental sustainability through the productive reuse of waste materials.},
