An investigation of the behavior of soil, soil-cement, and soil-cememt-fiber at different water contents and fiber contents is to study how the fiber (Polypropylene) effects the strength of soil (clay). Laboratory testings undertaken measured the stress-strain relationship by using a cubical multiaxial testing device. Experiments were set up for two different tests, Hydrostatic Compression (HC) and Conventional Triaxial Compression (CTC). For CTC, a confining pressure was simulated to match the stress that occurred under a county roadway. Soil used in this investigation was brought from Athens County Road 20. Soil moisture during testing was set at optimum water content (19%), 2 percent below, and 2 percent above optimum. Cement content was held constant at 6 percent of the weight of soil. The main objective of this investigation is to improve soils by adding cement and fibers at varying water contents.
