Evaluation of environmental waste in asphalt concrete

Industrial production and population growth have led to an increase in waste accumulation all over the world. Waste accumulation creates environmental and visual pollution. Waste storage areas are also gradually decreasing. Therefore, wastes are used in various production areas. In recent years, the rapid increase in waste and the limited storage areas have led scientists to accelerate studies on the use of waste in production. With the 2015 Paris Agreement, all countries of the world have been directed to work in the context of environmental pollution. In the preparation of this thesis, first of all, the wastes generated as a result of production in Eskişehir province were investigated. Ceramic wastes are also included in these wastes. This study was carried out with the R&D cooperation between Eskişehir Osmangazi University and İnönü Ceramic Factory. Turkey ranks ninth among the top ten countries in the world in terms of ceramic coating material production. Ceramic coating industry is one of the important groups within construction ceramics. In addition, Eskişehir-Bilecik-Kütahya region has an important place in terms of ceramic production and exports. Ceramic wastes can be categorized in 3 groups as floor, wall and filter mud wastes. The use of wastes in asphalt concrete was realized by replacing one of the two components of asphalt concrete, aggregates. In this study, for mix modification, 10%, 20%, 30% and 40% of the aggregate weight was replaced with coarse aggregates corresponding to ceramic waste gradation and performance evaluation was performed by applying Marshall Design. To support these studies, dynamic and static creep tests were performed. The test results obtained, it was proved that 20% of the ceramic wall waste can be used in asphalt concrete. In this way, efficient use of the country's resources can be achieved by reusing waste in production. In addition, sustainable environment and life can be improved.
