Steel Slag Road Tech

January 16, 2024

India’s First National Highway Steel Slag Road section on NH- 66 Mumbai-Goa National Highway was inaugurated recently.
Steel Slag Road Technology, developed by CSIR-Central Road Research Institute (CSIR-CRRI) is transforming the waste of steel industries into wealth and is helping the National Highways Authority of India (NHAI) to build stronger and ecofriendly national highways in the country.
The bituminous steel slag road is constructed with 28% less thickness compared to conventional bituminous roads on NH-66.
The construction process involved converting approximately 80,000 tons of CONARC Steel slag into processed steel slag aggregates.
- These exhibit superior mechanical properties compared to natural aggregates and have been used in all layers of the road, replacing traditional natural aggregates.
