This paper presents the effects of the waste tire, water content, and relative density on soil dominant frequency using the experimental application. In this study, metal cylindrical molds with a diameter of 30 cm and a height of 50 cm are prepared to understand the effects of these materials. These molds are filled with sand in different relative densities (60% and 80%). Also; the samples are prepared by adding waste tire particles at different rates (0%, 0.5%, 1%, 2%) to this sand for different relative densities and water contents (0%, 5%, 10%, 15%). The soil dominant frequency and H/V amplitude are determined with the microtremor technique by measuring at 60 minutes of measurement on each cylinder using a broadband seismometer. Microtremor data are analyzed by using the Horizontal/Vertical spectral ratio method. As a result of the experiments, it has been observed that the waste tire particles added to the sand affect the H/V amplitude in a decreasing way. It is detected that the most suitable environment is obtained to be 1% waste tire and 0% water content for 60% relative density. Moreover, the most suitable environment has been achieved in 0% water content and 0.5% waste tire ratio for 80% relative density. It has been concluded that the prepared composite material with waste tires may have positive effects on decreasing the earthquake devastating effects.
