Abstract :The issue of investigating the usability of waste materials in many different applications of civil engineering has attracted the attention of researchers until today. The additive material used for stabiliser is waste material that causes positive effects on the environment, engineering and economy. Studies on the use of waste materials, especially in improving road and foundation filling materials, have recently attracted attention. In this study, compaction parameters, California Bearing Ratio insert ignore into journalissuearticles values(CBR); with the soaked and unsoaked condition and unconfined compressive strength values of soil-crumb rubber mixtures were evaluated. To investigate these effects, crumb rubber with various percentages insert ignore into journalissuearticles values(2.5%, 5.0%, 7.5%, 10.0% and 15.0%); was added to clay soil taken from Eskisehir city in Turkey. CBR and unconfined compressive test results show that a 5.0% crumb rubber level is optimum. For 5.0% additive level, soaked and unsoaked CBR values increased by approximately 18% and 25%, respectively. The highest increase was seen at same additive level as 8% compared to pure clay specimen for unconfined compressive strength.
