One of the most serious issues in the geotechnical engineering is soil erosion which requires an appropriate engineering technique to deal with. The main objective of this paper is to analyze the effectiveness of treated natural fibers in reduction of surface erosion of soil slopes. For this purpose, a laboratory soil slope model of cross-sectional area 90 × 90 cm2 and slope angle of 45° is prepared using red soil. Naturally available jute geotextile fibers are used as surface protection layers on top of soil slope. The jute is treated with alkali activated binder (AAB) with different water to solid ratios (0.35, 0.40, 0.45). An aluminosilicate precursor (fly ash/slag) reacts with an alkaline activator solution including sodium silicate and sodium hydroxide to form AAB. An artificial rainfall arrangement is framed, as splash type soil erosion with two different flow rates of 500 and 900 lit/hr. Based on the discharge, the rainfall simulator arrangement is designed to have 2.97 mm diameter holes with center to center spacing of 5 cm. The runoff is collected over intervals of 5 min from the beginning of the simulated rainfall through 1-h duration, resulting in a total of 12 time intervals. Runoff volumes are measured, and the samples are oven-dried at 105 °C for 48 h to measure the yield of sediment. This procedure is implemented on both unreinforced and reinforced slope. It is observed that 0.35 AAB treated jute reinforcement reduced soil erosion by 93.17%, whereas for untreated jute, the same reduced by 90.6%. The study’s findings are useful to develop a cost-effective and environmentally responsible solution for reducing surface erosion.
