RECYCLED CONCRETE FINES AS A COMPONENT OF COMBINED STABILISATION OF CLAYEY SOILS FOR SUSTAINABLE ROAD CONSTRUCTION
This study investigates the application of recycled concrete fines (RCF) as a mineral modifier and hydrated lime as a traditional stabiliser of clayey soils used in road foundations. The incorporation of RCF was shown to reduce soil plasticity and improve the compactability of loam due to the skeletal effect of inert crystalline particles. Compressive strength tests confirmed the enhanced strength of the modified mixtures. The addition of lime promoted the formation of hydraulic products, providing further gains in soil strength and stability.
