A Study on Effect of Steel Slag as a Partial Replacement in the Performance of Bituminous Mix

The construction industry is the largest consumer of natural resources which led to depletion of good quality natural aggregates. This situation led us to explore alternative materials and granular slag a waste industrial by-product is one such material identified for utilization it as replacement of natural Aggregate. The demand for and utilization of industrial by-products and wastes in road pavements is increasing and becoming more important. Government policies and public awareness is also contributing to the enhancement of both this demand and utilization. Manufactured aggregates may reduce environmental strain by minimizing over exploitation and indiscriminative use of natural aggregates which we get from the mining, quarrying and blasting activities. Waste is not a waste unless you waste it. Steel slag has potential and may also be utilized if technical feasibility can be proven. Hence, the principal objective of this research was to assess the possibility of used of steel slag in road pavements. This paper focuses on the use of steel slag as partially replacement in bituminous mix as coarse aggregate with 10 %, 20% and 30% Steel Slag Proportion by weight of total weight of Mix.
