copper slag in mixes. Although adding copper slag had negative effect on indirect tensile strength of mixtures, the tensile strength rate (TSR) value emproved by replac ing CS in the mixtures [Hassan and AlJabri, 2010]. In this research, the usability of copper slag in warm mixed asphalt concrete was investigated in order to bear the
Copper Slag (CS) is a byproduct obtained during the matte smelting and refining of copper. It is classified as waste materials and, therefore, is considered as an environmental issue to cope with.
Copper Slag. Shape and Texture: Aircooled copper slag aggregates are black in color, and typically have a glassy appearance. Granulated copper slag aggregates are similar to aircooled copper slag aggregates but more vesicular. Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in hot mix asphalt.
Fine copper slag has reportedly been used in HMA pavements in California and granulated copper slag has been incorporated into asphalt mixes in Georgia to improve stability. Michigan Department of Transportation Specifications consider reverberatory copper slag to be a conventional coarse and fine aggregate for HMA pavement ( Gorai et al., 2003 ).
#0183;#32;This paper presents the influence of replacing limestone aggregates by copper slag on the performance of warm mix asphalt. Optimal Binder Contents () of asphalt mixes containing CS proportions of 0, 10, 20, 30 and 40% by total weight of aggregate
This paper presents the influence of replacing limestone aggregates by copper slag on the performance of warm mix asphalt. Optimal Binder Contents () of asphalt mixes containing CS proportions of 0, 10, 20, 30 and 40% by total weight of aggregate were determined using Marshall procedure.
In this research, friction and cohesive qualities of copper slag are exploited, in order to incorporate this slag as aggregate in asphalt mixes containing Reclaimed Asphalt Pavement (RAP). Results demonstrate that the use of copper slag in an addition percentage of 35% is favorable, because flow values increase and stability values decrease.
Copper slag (CS) is a derivativ e of copper production that is mainly composed of heavy metals. The large amount of this material accumulated around the world entails a serious environmental da...
Copper slag (CS) is a byproduct of the copper extraction process, which can be used as coarse and/or fine aggregate in hot mix asphalt (HMA) pavements. This study used CS as a replacement of the fine aggregate with a percentage of up to 40% by total aggregate weight.
#0183;#32;The use of copper slag reduces asphalt mix rigidity with RAP. Asphalt mix with copper slag perform better at low rather than high temperatures. A stiffening effect of fine material appears when copper slag exceeds 15% addition.

Copper slag is obtained as a byproduct of copper production, which is available in ample in India. In the year 2017, the volume of copper produced in India is nearly 134,790 metric tons. So many researchers studied the effect of copper slag on pavement construction and observed convincing results in improving the mechanical properties of the mix.
