This abstract provides a concise summary of the review conducted on the subgrade soil stability enhancement through the application of cow dung ash and rice husk ash. The study focuses on investigating the effectiveness of utilizing cow dung ash and rice husk ash as stabilizing agents for subgrade soil. Various laboratory tests and field evaluations were carried out to assess the impact of these organic materials on subgrade soil properties and stability. The ashes act as pozzolanic materials, reacting with the soil particles and forming cementitious compounds that enhance the soil's mechanical properties. The increased stability is attributed to the improved shear strength, reduced plasticity, and enhanced compaction characteristics of the soil. The utilization of these organic ashes offers additional benefits, such as cost-effectiveness, environmental sustainability, and waste management. By repurposing agricultural waste products, the study contributes to the promotion of eco-friendly practices in construction and geotechnical engineering.
