| Abstract: | Admixtures and reinforcement materials are frequently used in practice to stabilize coarse and fine grained soils and to improve
their engineering properties. However, a limited number of studies have been carried out on fiber-reinforced fine grained
soils. In this study, a series of unconfined compression tests, direct shear tests, and California Bearing Ratio tests were
carried out to investigate the effect of randomly distributed polypropylene fiber on the strength behavior of a fine grained
soil. The content of polypropylene fiber was varied between 0.25 and 1% by total dry weight of the reinforced samples. It
was observed that unconfined compression strength, cohesion intercept and California Bearing Ratio increased with the addition
of fibers. On the other hand, the results of the tests indicated that shear strength angle was not affected significantly
by the fiber reinforcement. |
