“…Other research carried out in Egypt, studied the effects of adding sawdust on the compressibility and shear strength characteristics of an organic clay from the city of Kafr Elsheikh where 5% cement was mixed with variable percentages of sawdust from 10 to 20%, it showed that the best results in the shear strength tests were obtained for a combination of 5% cement with 15% sawdust, while the combination of cement and sawdust gives better consolidation, the results are 5% cement with 10% sawdust [39]. Another study conducted in Pakistan analyzed the effect of the addition of variable percentages of the mixture of rice husk (0 to 21%) and sawdust (0 to 7%) applied to clay soil, mitigating their erosive potential and improving their parameters of shearing strength for the use on earthen embankments, observing that 5% sawdust and 15% rice husk are established as the optimal content for effective stabilization, and soil erosion control studied [112]. In Malaysia, the research analyzed the variation in the engineering properties of a peat-like soil with the addition of some percentages of sawdust varying from 2 to 5% and rice husk ash (RHA) with lime as an additive, as a result, it was observed a decrease in the value of the Atterberg limits, OMC, UCS, and MDD with the increase in the percentage of sawdust and rice husk ash added [24].…”

A frequent problem in Geotechnics is the soils with inadequate physical-mechanical properties before the efforts to which they will be subjected by the constructions, incurring cost overruns caused by their engineering improvement. The need to improve the engineering properties of soils is not recent, currently observing that the most common alternatives are binders such as cement and lime. The climate change observed in recent decades and the uncontrolled emission of greenhouse gases have motivated Geotechnical and Geoenvironmental researchers to seek mechanisms for soil reinforcement from a more sustainable and environmentally friendly approach by proposing the use of recycled and waste materials. An alternative is natural fibers, which can be obtained as waste from many agro-industrial processes, implying their high availability and low cost. Sawdust as a by-product of wood processing has a rough texture that can generate high friction between the fiber and the matrix of the soils, leading to a significant increase in its shearing strength and bearing capacity. This concept of improving the properties of soils using natural fibers distributed randomly is inspired by the natural phenomenon of grass and/or plants that when growing on a slope can effectively stabilize a said slope.

“…The soil's top layer in an embankment slope is more sensitive to erosion during rainstorms. It provides the least erosion resistance and rapidly loses strength [2]. The undrained condition of soil stability analysis was calculated by First Order Reliability Method (FORM), and Monte Carlo Simulation (MCS) method to calculate the Factor of Safety (FoS) in [3].…”

Heavy rainfall is often responsible for embankment failures. During intense rainfall, the embankment slope inclination is vital for slope stability. Some failures occur in the slope due to heavy rainfall and sudden change in the matric suction. Jute fiber is a reinforcing material that is added to improve soil strength. In this research, in order to explore the effects of slope inclination on soil stability, soil samples were collected and exposed to artificial rainfalls. This study presented various tests performed on the soil samples. Different tests like sieve analysis, permeability test, Direct Shear Test (DST), liquid limit, plasticity limit, and numerical modeling were conducted in the laboratory. The study's findings revealed that the failure is caused by a soil suction loss when the inclination of the slope is higher than the soil friction angle and the collapse is caused by the positive water pressure at the slope's toe when it is lower than the soil's friction angle. Furthermore, when the slope angle increases, the slopes are becoming increasingly vulnerable to rapid collapse. After that, jute fibers were combined with the soil to improve its performance. Samples of 2, 3, and 4 rows of jute fibers were tested. These jute fiber samples performed better than the ones without fibers under different rainfall conditions. The distribution of jute fibers had a favorable influence on both strength measurements and safety aspects. Utilizing the factor of safety and matric suction, the performance of jute fiber samples is superior to those without jute fibers. Consequently, by adding jute fibers the stabilization of the soil is significantly improved along with its factor of safety.
