Abstract

In the scope of the study, the usability of waste quartz sand, generated by glass factories, as a filler material in hot bituminous mixtures was investigated. Filler material was substituted in the mixture with 25%, 50%, 75%, and 100% of the limestone filler. The optimum bitumen ratios were determined. The strength values and moisture sensitivity of the samples subjected to the indirect tensile test were determined. Strength values showed better results compared to the reference sample. It was observed that the Tensile Strength Ratio (TSR) (%) was found to reach the peak at 50% content and determined that all samples provide the limit value of 80%. Hamburg Wheel Track test was applied to determine the track performance of the mixtures. Experiment results indicated that the best track performance was at 50% of the mixture. In addition, it was determined that the specification provides the maximum rutting value of 12.5 mm in all mixing ratios.
