In today's world, with the increasing population density, consumption habits are also changing and increasing rapidly in proportion to the population. The development of the industry, the transportation of products produced together, the increase in the rate of individual vehicle ownership have also increased the rate of vehicle tire usage significantly. This situation has led to the development of new environmental problems. Developing environmental problems have pushed countries to seek disposal of waste tires. In this study, it was used as an additive to hot asphalt as a disposal method of waste tires. The effect of waste tire on the physical and chemical properties of hot asphalt was investigated. Waste vehicle tires were granulated based on powder metallurgy principles with the help of water jet and a homogeneous mixture was provided with hot asphalt at 160 °C. Asphalt samples mixed with 2%, 4%, 6% and 8% rubber powder were prepared and subjected to Marshall test. The Marshall test results of the control sample obtained from hot asphalt without additives were compared. The waste tire ratio of the sample that provides the optimum value improvement was determined as 8%. Then, Indirect Tensile Strength Test, Bitumen Filled-Void Ratio Test, Breaking Energy Test, Loading Test, Tire Track Tests were applied to this sample. As a result, it was concluded that 8% waste tire additive had a positive effect on the physical and chemical properties of hot asphalt.
