Use of steel slag as railway ballast: A review

The higher dead weight of track can lead to the requirement of heavier sections in case of railway bridges. Further, the transportation costs of heavier steel slag can be slighter higher when compared to granite. However, the use of steel slag can lead to a reduction in the cost of ballast by about 25.3% [50].
