Özet: Clayey soils contain clay minerals known as smectite. These soils present problems to geotechnicalengineers due to their complex nature. Excessive compression, dispersive behavior, collapsingbehavior, low shear strength, high swell potential and frost susceptibility are some of the undesirableproperties of soils in geotechnical engineering. Soil properties such as those mentioned would causesevere distress to structures build on them. In this regard, it is necessary to reinforce and or stabilizethe soil. In this study, clayey soils were stabilized by using additive geo-material to improve theirengineering properties. For this purpose, quartzite known geological material was used as additive.In experimental study, the natural and stabilized clayey soil samples were subjected to the unconfinedcompression, the shear box, the odometer and the falling-head permeability tests after compactionat optimum moisture content. The test results indicated that quartzite enhanced both the unconfinedcompression strength and strength parameters. Consequently, it is concluded that the quartzite canbe successfully used for the modifications of clayey soils in the geotechnical applications.
