Roads Made from Steel Waste Material: technology transferred for sustainable road construction



The CSIR-Central Road Research Institute and ArcellorMittal Nippon Steel India have come together to transfer technology for steel slag road and processed steel slag aggregate. The goal is to use waste material in road construction and support the Prime Minister’s Waste to Wealth vision.

The Secretary in the Ministry of Steel, Nagendra Nath Sinha, emphasized that about 19 million tonnes of steel slag is produced in India every year, which will increase to 60 million tonnes by the year 2030. With steel slag road development, the waste material can be processed scientifically and used in road construction. This will not only benefit the environment but also speed up the government’s road development schemes.

Advantages of steel slag roads

Satish Pandey, Project Leader and Principal Scientist of the Steel Slag Road Research Project, explained that the thickness of the road made from processed steel slag will be less as compared to a normal road. This will reduce the requirement of material required in road construction, ultimately leading to a 30 to 40 percent reduction in the cost of road construction. The new technology reduces the use of bitumen, a non-renewable resource, and enhances the durability and strength of the roads. Steel slag roads have already been constructed in Gujarat, Jharkhand, Maharashtra, and Arunachal Pradesh under the technical guidance of CRRI.

The Future of Sustainable Infrastructure

The use of steel waste material in road construction is a sustainable solution for the future of infrastructure development. With the transfer of this technology, construction companies can reduce their environmental impact and promote eco-friendly practices. The development of sustainable infrastructure is crucial for achieving sustainable development goals and addressing global challenges such as climate change and resource depletion.

Conclusion

The use of steel waste material in road construction is a sustainable solution for the future, and the technology transfer to Indian construction companies is a significant step towards promoting eco-friendly practices in the industry. The adoption of sustainable infrastructure development practices is crucial for addressing global challenges and achieving sustainable development goals. The use of steel waste material in road construction is an excellent example of how waste can be repurposed to create a more sustainable future.
