This document summarizes research on using dolochar, a solid waste produced by the sponge iron industry, to stabilize soil for pavement construction. Dolochar contains silica and other compounds that can improve soil properties through pozzolanic reactions when mixed with soil. The document reviews several studies that found mixing dolochar into expansive soils reduces swelling, increases bearing capacity, and improves other geotechnical properties. Using dolochar for soil stabilization provides environmental benefits by reducing disposal of this industrial waste, while also improving soil quality at a lower cost. The research demonstrates dolochar can effectively stabilize soils and make them suitable for uses such as road and pavement construction.
