Abstract

To investigate and measurement of different variables effects such as type of fibers, weight percent (ratio of yarn dry weight and soil dry weight) and length of fibers on loading improvement of reinforcement weak sandy soil (with random distribution), was used artificial yarn such as polypropylene in CBR experiment. Conclusion of indicator in these experiments is increase of shear strength of sand mix with random distribution in 13.8 percent of humidity. But in further humidity, behavior of reinforcement becomes different. Lengthening of fibers till 12 millimeters, increases the loading strength by changing the percent of fibers; while more lengthening, leads up to reduce strength.

Keywords: Silty-sandy soil, Soil stabilization, polypropylene fibers, CBR.
