NEW DELHI, July 17 : Union Minister of State (Independent Charge) Science & Technology; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space Dr Jitendra Singh right now introduced that India has developed the world’s newest “Steel Road” expertise. He knowledgeable that CSIR- Central Road Research Institute (CRRI) , New Delhi, which was based in 1952, has pioneered the event of a revolutionary Steel slag street expertise which facilitates the large-scale utilization of waste metal slag from Steel Plants in street development.
The Minister additional disclosed that in June 2022, Surat in Gujarat grew to become the primary metropolis within the nation, or maybe world, to get a processed metal slag (industrial waste) street constructed as a part of a joint-venture venture by the Council of Scientific and Industrial Research (CSIR), Central Road Research Institute (CRRI), Union Ministry of Steel, authorities think-tank NITI Ayog, and Arcelormittal Nippon Steel (AM/NS), at Hazira.
Slag is made up of impurities melted out of the ore in the course of the steel-making course of in a lot of the Steel Plants.
Dr Jitendra Singh stated metal slag expertise in paving the roads is in tune with Prime Minister Narendra Modi’s “Waste to Wealth” Mantra. “This innovative technological initiative also addresses the problem of environmental degradation caused by waste steel slag and unsustainable mining and quarrying of natural aggregates. CRRI has developed several key technologies for sustainable utilization of waste materials in road construction”, he stated.
The stretch of six-lane street experimentally paved with slag from AM/NS plant has been proven to withstand beating from climate in addition to from 1000’s of heavy vans, despite the fact that the floor is 30% shallower than that of roads paved with pure aggregates.

The trial, guided by the CSIR-CRRI, means that roads constructed with the considerable waste materials blended with bitumen might be 30% cheaper than typical paving, and scale back the unsustainable mining of sand and gravel.
The Border Roads Organisation (BRO) additionally used metal slag to assemble a long-lasting heavy-duty street at Arunachal Pradesh alongside the India-China border space.  The metal slag materials was given by Tata Steel Ltd freed from price and transported from Jamshedpur to Arunachal Pradesh by Indian Railways freed from price. Besides, India’s largest street constructing company, National Highway Authority of India efficiently examined the Steel Slag Road expertise on NH-66 (Mumbai- Goa).
Dr Jitendra Singh, who visited the Central Road Research Institute right here right now, stated that the metal slag street not solely price about 30% cheaper than typical bitumen however they’re additionally extra sturdy and immune to climate vagaries.
“Steel slag roads have been found to last ten years as compared to three to four years for bitumen roads, thus bringing down sharply the maintenance costs. In Surat, the steel slag road top has been found to weather the erosive saline marine environment while in the cold, snowy and torrential rain prone toughest Himalayan terrain, the steel slag roads have been found to last longer” he stated.
During the go to, Dr Jitendra Singh additionally launched the CSIR ‘One Week One Lab’ programme. He additionally interacted with college students being performed on a guided tour of CRRI as a part of the ‘One Week One Lab’ marketing campaign.
Dr Jitendra Singh lauded the CRRI for partnering with the Central Electronics Engineering Research Institute (CEERI) in Pilani for an AI mission venture, which seeks to harness the ability of synthetic intelligence in transportation programs. During the go to, the Minister inspected the Mobile Cold Mixer-cum-Paver, particularly designed for developing roads in high-altitude areas, and the Patch Fill-Pothole Repair Machine, which permits fast and economical repairs of roads in each city and rural areas.
