Jindal Steel Creates World’s Longest Road Using Steel Slag

Jindal Steel Limited has achieved a major sustainability milestone by constructing the world’s longest road built exclusively with processed steel slag aggregates at Raigarh, Chhattisgarh. Developed in collaboration with CSIR-Central Road Research Institute (CSIR-CRRI), the 1.85-km, four-lane road has earned recognition from Guinness World Records. The project uses approximately 200,000 tonnes of processed electric arc furnace steel slag, transforming a steelmaking by-product into valuable infrastructure material. Processed steel slag has replaced natural stone aggregates throughout the pavement structure, reducing dependence on quarrying and supporting more sustainable road construction. The road is engineered to handle heavy commercial traffic, making it an important demonstration of steel slag’s potential in large-scale infrastructure projects. The initiative also strengthens India’s push toward a circular economy, where industrial by-products are reused instead of being discarded. Jindal Steel and CSIR-CRRI have also moved to expand the use of steel slag road technology through further collaboration. The project highlights how innovation in the steel industry can contribute to greener infrastructure while improving the productive use of industrial waste.
