Volumetric properties and leaching effect of asphalt mixes with electric arc furnace steel slag and copper mine tailings

This study focuses on the potential of electric arc furnace (EAF) steel slag and copper mine tailings as asphalt paving materials with respect to issues of volumetric properties and leaching. In this study, four different asphalt mixes were investigated; each contained EAF steel slag and copper mine...
