Abstract
Construction of roads requires huge quantity of aggregates not only for the paving surface but also for the base course and sub base course. And there is depletion of natural resources where we are using m-sand instead of natural sand and on the other hand there is lots of waste material been dumped on the land. And these kinds of materials can utilized for the construction purposes, out of which copper slag is one such material. Copper Slag (CS) is a by- product obtained during the matte smelting and refining of copper. It is classified as waste materials and, therefore, is taken into account as an environmental issue to deal with. It can be effectively used for construction of pavement layers. On the other hand, in order to save energy and reduce the amount of pollutants that are being released in the process of asphalt production, Warm Mix Asphalt (WMA) technology can also be employed. So this paper presents the influence of replacing fine aggregates by copper slag on the performance of warm mix asphalt and hot mix asphalt. We are incorporating copper slag in the asphalt mixes with varying percentages like 0%, 10%, 20%, and 30% by total weight of aggregate. And mix design for Bituminous concrete grade-2 is been performed for bitumen percentages of 5%, 5.25%, 5.5% and 5.75%. The specimen prepared with this mix design was evaluated for the stability properties. And it was observed that the maximum stability of 9.23KN and 9.1KN was achieved for OBC of 5.5% and copper slag content of 20% for HMA and WMA respectively.
