  • The use and advantages of slagvoestalpine

     · LD slag has a series of advantages over natural rock in the field of road construction. Greater hardness. Slag has a greater PSV (Polished Stone Value) i.e. greater resistance to wear. This is the result of its mineral composition. The consequences less wear and longer road lifetimes. Roads constructed using LD slag demonstrate reduced rutting.
