India Inaugurates First NH Steel Slag Road on Mumbai-Goa NH
Under the guidance of CSIR-CRRI, JSW Steel constructed a 1 km long, four-lane steel slag road section on the Indapur-Panvel Section of NH-66 Mumbai-Goa. Approximately 80,000 tons of CONARC steel slag were converted into processed steel slag aggregates at the JSW Steel Dolvi, Raigad plant. These processed steel slag aggregates, superior to natural aggregates in various mechanical properties, were used in all layers of the road, replacing natural aggregates. The road features both bituminous and cement concrete steel slag sections on the right-hand side (RHS) and left-hand side (LHS) carriageways.
Shri G S Rathore, Chief Operating Officer, JSW Steel Ltd, praised the efforts of CSIR-CRRI and expressed gratitude for the support received from NHAI in making the project successful. Dr. Manoranjan Parida, Director, CSIR-CRRI, highlighted that CSIR-CRRI, in collaboration with different steel industries, has successfully utilized steel slag in road construction in various states.
Shri Anshumali Srivastava, NHAI Regional Officer, Mumbai, and Chief General Manager, noted that the steel slag road section features innovative technological aspects, exceptional performance, and has received appreciation from NHAI. Shri Satish Pandey, Principal Scientist CSIR-CRRI and Project Leader of the Steel Slag Road project, shared that both the bituminous and cement concrete steel slag road sections are approximately 32% more economical than conventional roads and demonstrate better durability. The bituminous steel slag road is built with 28% less thickness than conventional bituminous roads on NH-66.
