The Usage of Copper Slag in Bituminous Mix

This report basically discusses the researches done and basic understanding of the chosen topic, which is 'The Usage of Copper Slag in Bituminous Mix'. Copper slag is produced as waste from roasting of copper, in which sulphur (as S02 ) is eliminated. Disposal of many million tons of wastes such as copper slag is responsible for health hazards and degradation of environment. The purpose of the research is to determine the performance of the asphalt pavement with the existence of copper slag, compared with the conventional asphalt pavement. The use of copper slag, in hot bituminous mixes is to enhance the pavement performance, to protect the environment and to provide low cost roads is the need of hour. There have been researches done where copper slag was used as fine aggregate (up to 30%) or filler in the design of bituminous mixes like Bituminous Macadam, Dense Bituminous Macadam, Bituminous Concrete and Semi-Dense Bituminous Concrete. The addition of copper slag in various bituminous mixes provides good interlocking and eventually improves volumetric and mechanical properties of bituminous mixes. The research is conducted by adding the copper slag to substitute the filler in the asphalt mixtures while finding the optimum mix. The mixes are made to comply with the standards of the pavements done in the industry set by Jabatan Kelja Raya (JKR) and Projek Lebuhraya Utara-Selatan (PLUS). Tests are done on the aggregates used for the mix and also on the hot mix asphalt and based on the result it is found that copper slag can replace the use of cement in bituminous mix while also increase the quality of the pavement
