The Use of Asphaltites in the Landfill Layer
The waste materials emerged in developing cities should be disposed without damage to environment. Landfills must properly be designed and well managed. Recently, some waste materials were began to be used with clay in landfill layer design. This process was positive effects on environment by means of recycling, regains to economy and reducing environmental pollutions. In this study, asphaltite dust was added at ratio of 5%, 10% and 15% to mixture of 90% kaolinite and 10% bentonite by weight. Geotechnic, physical and chemical experiments were carried out on the samples. The experiment results were in acceptable limits with the literature, United States Environmental Protection Agency and the Turkish solid waste regulations. As a result, the asphaltite can be used as an additive material in landfills.
