Utilization of marble piece wastes as base materials

Abstract

With the increasing population, the limited natural sources are decreasing and environmental pollution is increasing. In recent years, the increase in industrial wastes and the high cost of disposal methods of these wastes have necessitated the evaluation of industrial wastes in industrials businesses. Truck tires, blast furnace slag, fly ash, waste concrete, and dismantled asphalt coverings can be listed as industrial wastes. If these wastes are used, environmental pollution is reduced, and contributions are made to the country's economy. In this study, an evaluation of marble waste as base material was performed. In this scope of work, physical tests, a modified Proctor test, a dry/wet California bearing ratio test, and density of soil in place by the sand cone test were conducted. Also, X-ray diffraction, X-ray fluorescence, and mercury intrusion porosimetry analyses were performed on these marble waste. As a result, the physical and mechanical properties of marble waste were determined. In conclusion, marble waste has been found suitable as a base material according to the Technical Specifications of Turkish Highways.
