Gujarat’s Surat is the first Indian city to urge a road built from processed steel slag (industrial waste). This road has been developed as a joint-venture project by the Central Road Research Institute (CRRI), Council of Scientific and Industrial Research (CSIR), NITI Aayog, Union Steel Ministry, and ArcelorMittal-Nippon Steel (AM/NS), at Hazira, a suburb of Surat covering all the landmarks of importance.
The construction of this road began a year ago. it had been done by converting mounds of steel waste into steel slag. This road has six lanes, with three lanes on either side. Heavy-duty vehicles of multinationals that are located within the industrial estate on Surat’s outskirts are using this road.
This steels road’s construction cost is 30% cheaper than the roads that are built using natural aggregates. Also, this road’s thickness is 30% lesser than the traditional ones. As steel slag is employed to construct this road its durability is way longer. As far as the implementation is concerned, this project has been implemented under the Waste to Wealth and Clean India Campaign initiative.
The slag that was wont to build this road was generated from a steel furnace that was burning at 1500 to 1600 degrees centigrade within the type of molten flux material.
The molten material was then poured into slag pits so they’ll be cooled and was processed further to develop the stable steel slag aggregates that were wont to build the road. The constructed road required around 1 lakh a lot of processed steel slag.
The steel slag road has been constructed using pressure cells, strain gauges, thermocouples, and displacement gauges to live deformation that’s load-induced. This road is going to be monitored by CSIR CRRI for an additional year. over 30 heavy-loaded trucks are using this road on a daily
