Abstract:  Copper Slag (CS) is produced as waste from roasting of copper, in which sulphur (as SO2) is eliminated. CS was used as fine aggregate (up to 30%) in the design of bituminous mixes like Bituminous Macadam, Dense Bituminous Macadam, Bituminous Concrete and Semi-Dense Bituminous Concrete. Mechanical properties of mix such as Marshall stability, Indirect Tensile Strength was determined. Addition of CS as fine aggregate in various bituminous mixes provides good interlocking and eventually improves volumetric and mechanical properties of bituminous mixes.
