BRO to build durable steel slag road in Arunachal

19 Aug 2022 CW Team

Steel slag, which can survive heavy rain and adverse weather conditions, will be used by the Border Road Organisation (BRO) in its prototype road project in Arunachal Pradesh. If this proves to be successful, building strong roadways in prominent locations may become simpler. A six-lane highway connecting the port with the city was opened in Surat, Gujarat, in June of this year using the same technology.

Slag is a by-product of the production of steel. The Indian Railways has also sanctioned a significant research and development (R&D) project to the Council of Scientific and Industrial Research (CSIR) and Central Road Research Institute (CRRI) to explore the possible utilisation of steel slag aggregate as railway ballast for track construction and maintenance. The National Highways Authority of India (NHAI) will also use steel slag for the construction of a portion of the Mumbai-Goa highway.
