Nowadays, in addition to several classic mechanical improvement methods, lightweight fill materials are used to reduce earthquake and vibration loads acting on the ground, as well as to minimize soil settlements. In recent years, the use of lightweight fill systems in geotechnical engineering has grown more common. In retaining structures, lightweight fill materials are also used to reduce the forces that impact the structure. Likewise, it makes it likable to utilize lightweight fill materials in order to lessen the loads on city center subsurface structures. In this study, the geotechnical properties of the lightweight fill materials which included EPS (Expanded Polystyrene Foam), waste tire, sand and cement materials as lightweight fill material were investigated. The L25 design model relevant to the Taguchi method was applied in the experimental study. The cement/mixture (EPS + waste tire + sand) weight ratios in designs include 8/1, 10/1, 12/1, 14/1, and 16/1. cement/water ratio was kept constant, EPS and waste tire in the mixture were used at rates ranging from 10% to 50% by weight. Unconfined compression, California bearing ratio (CBR), and freeze-thaw cycle tests were performed on the produced specimens, and the 'optimal mixing ratio for lightweight filler was investigated. As a result of the experiments, it was observed that the strength increased as cement ratios in the mixtures increased, whereas the strength reduced when the EPS ratio increased. Taking into consideration the ratios used in the study. Waste tires were found to have no impact on the designs' strength.
