India has opened the country's first road using metallurgical slag on the NH-66 highway connecting Mumbai and Goa, thanks to the CSIR-CRRI Transformative Steel Slag Road technology.
The construction of 1 km of the road used 80,000 tons of CONARC Steel slag, The Financial Express reports.
It is noted that the technology can open a new milestone in sustainable road construction, in particular by recycling industrial waste into valuable resources.
CSIR-CRRI Chief Scientist and Project Leader Satish Pandey emphasized that the bituminous steel slag road is 28% thinner than traditional bitumen pavement. In addition, the new sections are 32% more economical than classic roads and more durable.
CSIR-CRRI Director Dr. Manoranjan Parida said that the research project is also developing national guidelines for the use of processed steel slag in road construction.
Earlier, EcoPoliti wrote, that in Odesa region in the Podilskyi district they started to rehabilitate the road using ash, which reduced the costs of the works by 30%.
As EcoPolitic previously reported, the company "DTEK Energo" was the first in Ukraine to build 900 m of road in the area of the Burshtyn TPP using ash slag – a product of coal combustion.
