India’s Union Steel Minister Mr Ram Chandra Prasad Singh has inaugurated India’s first road constructed entirely from a specially designed slag produced by ArcelorMittal Nippon Steel India. Steel Minister said “The milestone project came to fruition from AM/NS India s commitment to recycle and reuse by-products from its steelmaking operations, which is commendable. As India's steel industry grows, so too must industrial innovation that ensures sustainable, circular manufacturing growth.”
AM/NS India CEO Mr Dilip Omen said “Supported by the CRRI, AM/NS India is proud to have developed an alternative to natural aggregates in road construction, which is of international quality’ standards, cost competitive, and reduces the burden on natural resources. Part of the Waste to Wealth and Clean India Campaign, the first-of-its-kind initiative not only validates our quest to contribute to a circular economy, but also sets a new benchmark for others to emulate”
The 1 km six-lane road in Surat was constructed using around 1 lakh tonnes of processed steel slag from AM/NS India’s Hazira manufacturing plant, which was developed in collaboration with Council of Scientific and Industrial Research laboratory Central Road Research Institute. The Hazira road used around 100,000 tonnes of processed steel slag. According to the Indian Road Congress guidelines for construction of a heavy traffic road that is capable of taking the load of 1,000 to 1,200 trucks per day, around 600 to 700mm thickness of road layers are required on the foundation with 8% California Bearing Ratio. CRRI Principal Scientist Mr Satish Pandey had said that the construction cost of the processed steel slag road is 30% cheaper than roads built from natural aggregates as the thickness of the road is 30% lesser than normal ones, while the durability is much longer due to the utilization of steel slag. The CRRI is now preparing guidelines and specifications for the utilization of steel slag in road construction. The parameters and performance indicators will be incorporated in the road guidelines and will be given to Indian Road Congress, Ministry of Roads and Highways, to utilize steel slag for the constructions of national highways.
