This research would entail determining the shear strength of reinforced sand with geotextile using triaxial compression tests. A triaxial compression test was done at the laboratory to study the stress-strain behavior of the geotextile and sand. The geotextile-sand aggregates were subjected to the variation of confinement pressures and by using different geotextile layers. The experimental results showed that the inclusion of geotextile fibers improved the maximum shear strength and axial load to failure of the specimens. After an unreinforced soil, the reinforced samples show more shear strength as compared to knowing an axial strain of 1-1.5%. This means that a sufficiently great deformation is required before the geotextile works to develop its tensile behavior and improve the shear strength of the reinforced soil.
