Council of Scientific and Industrial Research, Central Road Research Institute, Ministry of Steel, NITI Ayog & ArcelorMtttal-Nippon Steel India has executed a joint-venture project to build a road with steel slag aggregate. ArcelorMittal Nippon Steel India tweetd “We're happy to partner with @CSIR_IND & @CSIRCRRI to develop India's first steel slag road: a cost-effective and environment-friendly alternative. It wouldn't have been possible without the strategic support of @SteelMinIndia @NITIAayog @NHAI_Official @CMOGuj & @Steel_Indian”The six-lane public road is a kilometer long stretch in Hazira, which also houses the AM/NS plant. The construction began around a year ago by converting mounds of steel waste into steel slag aggregate. The sixth and final lane of the road, with a three-lane to-and-fro carriageway on either side, was completed in early March. The road is now being used by heavy-duty vehicles of multinationals located in the industrial estate on the outskirts of Surat. 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 700 mm thickness of road layers are required on the foundation with 8% California Bearing Ratio. CRRI Principal Scientist Mr Satish Pandey 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 utilisation of steel slag.The CRRI will now prepare guidelines and specifications for the utilisation 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 utilise steel slag for the constructions of national highways.
