Geotextiles and jute fibers both have been successfully used for reinforcement of soils to improve the bearing capacity. In the present study, firstly the geotextile is used as a tensional material for reinforcement of granular soils. Laboratory California Bearing Ratio (CBR) tests were performed to investigate the load-penetration behavior of reinforced and unreinforced granular soils with geotextile. By placing geotextile at certain depth within sample height in one, two or three layers were tested under soaked condition to investigate the effects of the number of geotextile layer on the increase in bearing capacity. Secondly, laboratory tests were performed to investigate the behavior of granular soil reinforced with jute fiber of various aspect ratio mixed with soil at 0.5%, 1.0%, 1.5%, 2.0% by weight of the soil. Finally, the granular soil was reinforced with the combination of geotextile (top and middle layer of the sample) and jute fiber (0.5% and 1% by the weight of soil). The experimental results were then studied and compared to determine the most effective combination of geotextile and jute fiber to reinforce the studied granular soil.
