Interface friction between soil and fiber and their interlocking are considered as fundamental factors of mechanical improvement of fiber-reinforced soils (so-called internal reinforcing). In order to study the quantitative effects of the surface roughness fiber on strength and deformational properties, box shear and unconfined compression tests were carried out using cohesion less soil (Toyoura sand) and cohesive soil (a mixture of Toyoura sand and Kaoline clay).It was found from the test results that both internal friction and cohesion components were increased with the mixing rate of fibers, and the higher degree of fiber's surface friction improved their peak strength, residual strength and ductility.
