Abstract

Copper Slag (CS) is obtained as a by-product from the copper industry having heavy metals in its constituents. Most of the developed countries have specification to use it as construction material. Despite this, large amount of CS is disposed of in stockpiles and this arises serious environmental problems across the globe. The production of asphalt mixes with CS as a replacement of natural aggregate (CA) would limit the environmental hazard. The purpose of this paper is to review the physical, mechanical and chemical properties of CS which could be utilized as road construction material in asphalt mixes. Several studies have found improved engineering properties of CS with RAP (Reclaimed Asphalt Pavement), HMA (Hot Mix Asphalt) and WMA (Warm Mix Asphalt) and suggested that 10-30% of CS as fine aggregate is satisfactory as optimum proportion in asphalt mix.
