![]() #Steelslag road built with 100 % processed steel slag aggregates in all layers of bituminous roads at Hazira, Surat in collaboration of & under the R&D study sponsored by /dNHxxdnAZA- CSIR CRRI March 22, 2022 The molten material is poured into the slag pits for cooling as per the customised procedure and further processed to develop stable steel slag aggregates, with “better material properties in place of the natural aggregate commonly used in road constructions. ![]() The slag is generated from a steel furnace burning at around 1,500-1,600 degrees centigrade in the form of molten flux material as an impurity. Steel slag road is built with 100 percent processed steel slag, which aggregates in all layers of bituminous roads at Hazira, Surat. India’s first-ever ‘steel slag road’ was laid by ArcelorMittal Nippon Steel India in collaboration with CSIR India. A road made with steel waste has come up in the city of Surat in Gujarat at the Hazira Industrial Area. In the first such use case, waste steel has been utilised in India for constructing a road in Surat. The utilisation of waste as a construction material is being experimented with across the country.
