BRO to build a steel slag road in Arunachal Pradesh

01 Aug 2022

Steel slag, which can survive torrential rain and unfavourable weather conditions, will be used in the Border Road Organisation's (BRO) prototype road project in Arunachal Pradesh. If this is shown 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. While the project would be a first for the BRO, it was created entirely out of processed steel slag. 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 the steel slag for the construction of a portion of the Mumbai-Goa highway.
