One method for rehabilitation of weak and problematic soil properties is rehabilitation by using physical added material such as fibers. In this paper, effect of glass fiber on rehabilitation of clay soil mechanical properties is studied. The main goal of this paper is evaluation of how added glass fiber to clay soil can affect engineering properties of soil, particularly unconfined compression strength and elasticity modulus of reinforced soil. In this research five different composition of soil and glass fiber (0.5 to 2.5) per cent with 11, 13 and 15 per cent water content are used. In order to study the effect of water content and glass fiber, unconfined compression tests have been done on clay soil reinforced by fiber glass and unreinforced clay soil. Obtained results in this research show that adding glass fiber to clay increases highly unconfined compression strength and elasticity modulus of the reinforced clay. Increasing fiber glass and water content, increases failure strain and makes difference in failure situation of the reinforced clay. Increasing water content in samples, increases ductility and failure strain of reinforced clay and decreases unconfined compression strength and elasticity modulus.
