    Abstract :

    India is the 3rd largest steel producer in the world with total steel production of 95.6 MT per annum. Steel slag is the major by- product of steel industry and the current utilization of steel slag is less than 30%, far behind the developed countries. The largest part of generated steel slag still ends on often non-regulated landfills as industrial waste in adjoining areas. Disposal of steel slag as landfills leads to serious pollution to the environment. The sustainable development concept requires a more efficient management of waste materials and preservation of environment. Steel slag can be used potentially as a sustainable material in construction of pavements as India has world’s second largest road network in terms of length with a total road length of 4.24 Million Km. Large scale highway construction in India, emanating from rapid development has caused massive depletion of scarce natural aggregate. This paper provides an overview on the worldwide utilization of steel slag to resolve this problem and also the important routes and critical problems for large-scale utilization of steel slag were proposed.
