In this study, the usability of the waste olivine material obtained as a result of enrichment of chromite ore in Eti Krom plants as fillers in flexible superstructures was investigated. In the first stage, the rate of fixed fillers in the gradation obtained by using traditional crushed stone powder was taken as 4.7% and the optimum bitumen percentage was obtained by taking the bitumen rate as 3.5%, 4.0%, 4.5%, 5.0%, 5.5%. In the second stage, stability, flow, practical specific gravity, percentage of voids, percentage of asphalt filled voids and aggregates to the deposits created by replacing olivine in the ratio of 25%, 50%, 75% and 100% to the traditional crushed stone powder with the optimum percentage of bitumen found in the first stage. Percentage of gap was tested. According to the results, the changes in the engineering properties of asphalt concrete were compared according to the olivine percentages substituted with traditional crushed stone filler material.
