In line with Centre’s ‘Waste to Wealth’ mission and encouraging environmentally sustainable National Highways construction, trial use of ‘Steel Slag’ in road construction has been initiated by central road making agency NHAI. This initiative will help to address challenge of shortage of material used in development of the National Highways, and could replace natural aggregates such as sand, gravel, or crushed stone with the waste material from the steel industry.
To construct India’s first Pavement Quality Concrete (PQC) with steel slag, The National Highways Authority of India (NHAI) started trials for its possible use in road construction.
