2.2. Jute Geotextile

Jute Geotextile is a highly significant product made from Jute fiber. It has numerous applications in several industries such as civil engineering, where it can be used as soil erosion prevention, road pavement building, and river bank protection. This product is biodegradable and but has a similar function as synthetic geotextile. The jute geotextile selected for the study is a woven material commonly found in the form of jute bags. 2.3. Methodology The experimental analyses were conducted according to the Indian standard code of practice. The sand obtained from the river bed was oven dried in a laboratory at a temperature of 105 ℃ for duration of 24 hours. The triaxial test specimens were manufactured with a dia of 100 mm and a height of 200 mm. The dried sand that had been prepared was placed into a rubber membrane that was stretched within a split mould by using a vacuum pump. It was then compacted in multiple layers using a tamper. The specimens were kept at a relative density of around 60% and had a unit weight of 15.2 kN/m3. The following combinations have been analysed to determine the most efficient reinforcing system for tri-axial compression tests:
