JSW Steel became part of the history by constructing a 1-km-long four lane steel slag road section on Indapur-Panvel Section of NH-66 Mumbai-Goa, part of India’s first National Highway Steel Slag Road. For construction of this road around 80,000 tonnes of CONARC steel slag were converted as processed steel slag aggregates at JSW Steel Dolvi, Raigad plant.

Dr. V.K. Saraswat, Member (S&T), Niti Aayog, has inaugurated India’s first national highway steel slag road section on NH-66 Mumbai-Goa National Highway.
Dr Saraswat said the Steel Slag Road Technology, developed by CSIR-Central Road Research Institute (CSIR-CRRI), is transforming the waste of steel industries into wealth and helping the National Highways Authority of India (NHAI) to build stronger and eco-friendly national highways in the country.
JSW Steel, under the CSIR-CRRI technological guidance, has constructed the 1-km-long four lane steel slag road section on Indapur-Panvel Section of NH-66 Mumbai-Goa.
For construction of this road around 80,000 tonnes of CONARC Steel slag were converted as processed steel slag aggregates at JSW Steel Dolvi, Raigad plant.
The processed steel slag aggregates are superior to natural aggregates in terms of various mechanical properties and utilised for steel slag road construction in all layers of the road in place of natural aggregates.

The road has a bituminous and cement concrete steel slag road section at the same location in RHS and LHS carriageways. On this road section, the processed steel slag aggregates and slag cement have been utilised for construction of the cement concrete road in all layers.
Mr. GS Rathore, Chief Operating Officer, JSW Steel Limited, appreciated the efforts put in by CSIR-CRRI and the support JSW Steel Limited received from NHAI in making this project a success.
Dr. Manoranjan Parida, Director, CSIR-CRRI, said that CSIR-CRRI, under a sponsored research project of the Union Ministry of Steel, is developing national guidelines for utilisation of processed steel slag in steel slag road construction.
He added that CSIR-CRRI, in collaboration with different steel industries, has successfully utilised steel slag in road construction at Gujarat, Jharkhand and Arunachal Pradesh.

NHAI Regional Officer, Mumbai and Chief General Manager, Mr. Anshumali Srivastava, stated that the steel slag road section is known for its novel technological features and exceptional performance, and garnered appreciation from the National Highways Authority of India (NHAI).
Mr. Satish Pandey, Principal Scientist CSIR-CRRI and Project Leader of the Steel Slag Road project, informed that the bituminous steel slag road on NH-66 is built with 28 percent less thickness in comparison to conventional bituminous road on NH-66, while cement concrete section is built at identical thickness.
Both the road sections – bituminous and cement concrete are around 32 percent economical in comparison to conventional roads and found to have better durability, he added.
