ABSTRACT
In this study, the usability of Sulphur Factory Waste (SFW) in Hot Mix Asphalt (HMA) as the filler material is investigated. Firstly, standard tests on the SFW have been done to determine the soil class. Next, optimum binder content and aggregate gradation are determined in accordance with Superpave volumetric mix design. The SFW is substituted into the HMA as filler material in four different rates (25, 50, 75 and 100%). Optimum binder content for each SFW ratio is determined. Superpave gyratory compactor is used for the compaction of the specimens. Prepared specimens have been tested for the indirect tensile strength. As a result, SFW has been increased the optimum binder content by 9.1%. Indirect tensile strength values of the specimens have been increased by 36.4%.
