Study of warm mix asphalt using reclaimed asphalt pavement and copper slag: a review

The incorporation of copper slag (CS) in asphalt pavements proves to be a good substitute in replacing the natural aggregates. This reduces pavement construction cost and plays a key role in protecting the environment. The CS can be used with Recycled Asphalt Pavement (RAP) material especially in Warm Mix Asphalt (WMA) pavements. The use of CS in pavement construction sector eliminates the disposal as well as leaching problems associated with it. This paper focuses on the review of studies carried out on the use of CS along with RAP in road construction. It analyzes the requirement/advantage of using CS with RAP in asphalt pavements in light of previous research findings and its influence on various engineering properties in pavements. This paper also reviews the work done to study the environmental impact of using CS in asphalt mixesThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
