Steel slag road technology is a revolutionary innovation that can enable the Border Roads Organisation (BRO) to construct long-lasting heavy-duty roads in strategic border areas, particularly in hilly states like Arunachal Pradesh. This technology utilizes processed steel slag aggregates in place of natural aggregates for road construction, which conserves the ecology and mountainous topography of the region. The technology has been well tested in multiple projects across India, and leading steel companies are working with CSIR-CRRI to produce wealth from waste. This collaborative effort between BRO, CRRI-CSIR, Indian Railway, and Tata Steel aligns with Prime Minister Narendra Modi’s vision to convert waste to wealth. The pilot project for this technology was executed by 119 RCC of 756 BRTF under Project Arunank officer commanding Roshan Kumar. This initiative has received appreciation from Prime Minister Narendra Modi and will have a positive impact on both the infrastructure and environment of the region.
Steel Slag Road Technology is set to revolutionize the road-building process of Border Roads Organisation (BRO) in strategic border areas, particularly in hilly states such as Arunachal Pradesh. According to Dr. V.K Saraswat, a member of Niti Aayog, the CSIR-CRRI Steel Slag Road Technology will enable the BRO to construct long-lasting heavy-duty roads, while also conserving the ecology and mountainous topography of the region.
A pilot project for the technology has already been undertaken by BRO on a 1-km stretch of the Joram-Koloriang Road in Arunachal Pradesh, with a team from CSIR-Central Road Research Institute, Tata Steel, and Lower Subansiri DC Bamin Nime conducting an inspection of the site. Dr. Saraswat emphasized the importance of using alternative road materials, such as processed steel slag aggregates, in place of natural aggregates for road construction.
The steel slag road section constructed by BRO’s Project Arunanak Division under CSIR-Central Road Research Institute, New-Delhi, utilized processed steel slag aggregates supplied by Tata Steel Jamshedpur plant. Approximately 1200 MT processed steel slag aggregates were transported from Jamshedpur to Itanagar via railways and then to the project site near Ziro by road.
Dr. Satish Pandey, Principal Scientist and inventor of steel slag road technology at Central Road Research Institute, highlighted that the waste product of steel manufacturing units called steel slag is utilized in the form of processed steel slag aggregates to construct 40mm thick bituminous surfacing on the BRO stretch. Steel slag bituminous surfacing, due to its inherent high strength and stiffness, is expected to offer a more durable heavy-duty road surface even in the face of inclement weather conditions in the region.
BRO Arunank Chief Engineer Brig AS Kanwar reiterated that the use of steel slag for road construction was an initiative taken up under the aegis of Niti Aayog as an inter-ministerial collaboration task between the Ministries of Defence, Science and Technology, Steel, and Indian Railways. He also highlighted the various technological initiatives of BRO across various border states, including Arunachal Pradesh.
The project has received appreciation from Prime Minister Narendra Modi for its positive impact on both the infrastructure and the environment of the region. With this new technology, BRO will be able to build long-lasting heavy-duty roads in strategic border areas, while also contributing to the conservation of the ecology and mountainous topography in hilly states like Arunachal Pradesh.
Dr. Saraswat commended the Border Roads Organisation (BRO) for their innovative work in constructing roads in difficult terrain and weather conditions. He also appreciated the collaborative efforts between BRO, CRRI-CSIR, Indian Railway, and Tata Steel to convert waste to wealth in line with Prime Minister Narendra Modi’s vision.
Under CSIR-CRRI technological guidance, steel slag road technology has been well tested in multiple projects across India. The first steel slag road was built at Hazira in Surat, followed by the second at NH-33 Jamshedpur, and the third at NH-66 Mumbai to Goa Highway at Maharashtra. Leading steel companies such as AMNS India, TATA Steel, JSW Steel, and RINL are also working with CSIR-CRRI on this technology.
TATA Steel EIC IBMD Division Dasgupta reaffirmed TATA Steel’s commitment to supporting green initiatives through all possible means, including strengthening strategic roads in the country through public-private partnerships.
The pilot project steel slag road at Joram Koloriang road was executed by 119 RCC of 756 BRTF under Project Arunank officer commanding Roshan Kumar. Lower Subansiri Deputy Commissioner Bamin Nime also visited the steel slag road site along with a few HoD’s.
