“…In addition, the concentration in sample E increased over time. This increase in E has also been reported by several researchers who used different types of fibers, such as plastic fibers [16], sisal fibers [26], polypropylene fibers [12], and jute fibers [14].…”

The exploration of oil palm empty fruit bunch (OPEFB) fiber as a construction material, especially in geotextile applications, is a growing area of interest. However, OPEFB fibers degrade rapidly, particularly in soil conditions, due to their natural composition. This study investigates the application of an alkaline solution, sodium hydroxide (NaOH), for enhancing the fiber strength and durability. OPEFB fibers, sourced from a palm oil mill in the Tanah Bumbu Regency, were treated via immersion in a 1N NaOH solution for 90 min. Subsequently, these treated fibers were embedded in soft soil and cured for 1, 7, 14, and 28 d under both open and closed conditions (that is, covered with plastic wrap). Tensile strength was assessed using specialized equipment designed for this purpose. Additionally, the fibers were blended with soil at a percentage of 7% based on dry weight, and compacted with 10% water content and a dry volume weight of 16 kN/m 3 . These samples were then tested for compressive strength, revealing a substantial improvement in the average tensile strength of fibers treated with NaOH at 288.22 MPa, which is 2.77 times greater than untreated fibers. Furthermore, the treated fibers exhibited enhanced durability, with tensile strength ranging between 160.2-179.58 MPa under closed and open conditions, respectively. Additionally, the compressive strength of the soil with treated fibers exceeded that of the soil with untreated fibers. Microscopic analysis revealed that the morphology of the treated fiber was denser and free of surface impurities, contributing to its improved performance.

“…Considering the Young's modulus [44], the addition of this fiber also resulted in an increase in sample consistency from very soft (i.e., E<4 MPa) to stiff in 1-7 days (i.e., 7<E<20 MPa) and to hard after 14 days (i.e., 20<E<32 MPa). Several researchers have also noticed this rise in the stiffness of fiber-reinforced soils [45][46][47][48]. The increase in strength and stiffness is only for samples with the addition of a 10 mm long fiber.…”

Natural fibers are already being used to stabilize the soil. However, the exact mechanism by which natural fibers improve the shear strength of soil is still not clear, and it varies according to the morphology of each fiber. Its durability in the soil is also an important issue in the use of natural fibers for soil stabilization. This study focused on the strength and durability of oil palm empty fruit bunch (OPEFB) fiber as a stabilizing material for soft clay. The durability was determined according to the changes in tensile strength and friction of the soil after a certain period. The clay was obtained from Banyu Hirang in South Kalimantan. The OPEFB fiber was obtained without further treatment from a palm oil processing plant. Tensile, soil-fiber friction, and unconfined compression tests were conducted for mixtures of fiber and soil. Preparations were made for each test with the same duration and conditions (1, 7, 14, 28, and 90 days) in closed and open conditions. The results showed that the average tensile strength of the fiber before use was 101 MPa. This value decreased sharply after 14 days in the soil, leaving a strength of 35.71 MPa in the open condition and 23.89% in the closed condition on the 90th day. The soil-fiber friction increased with increasing time, reaching 0.15 MPa in both conditions from the initial value of 0.06 MPa. The compressive strength of the soil-fiber mixture also increased with time. The corresponding scanning electron microscope results strengthened the findings of this study.

“…The triaxial test and California Bearing Ratio (CBR) test were carried out on unstabilised and stabilised soil. According toLal et al (2020), the results of the California Bearing Ratio (CBR) test and the triaxial test show that the layered arrangement of the jute fibre reinforcement significantly improved the strength and stiffness properties of the soil. In addition, it can be concluded that placing two layers of jute fibre reinforcement is more effective than one or three layers Prasanna et al (2020).…”

Subgrade soil is an essential component in the design of road structures as it provides lateral support to the roadway. One of the main reasons for pavement failure is subgrade settlement, which leads to a loss of subgrade strength. If the mechanical properties of subsoils are lower than required, a soil stabilisation method may be an option to improve the soil properties of the weak subsoil. Soil stabilisation is one of the techniques for improving poor subsoil, which results in significant improvement in tensile strength, shear strength and bearing capacity of subsoil. Soil stabilisation can be broadly divided into four types: thermal, electrical, mechanical, and chemical. The most common method of improving the physical and mechanical properties of soils is stabilisation with binders such as cement and lime. However, soil stabilisation with conventional methods using cement and lime has become uneconomical in recent years, so an alternative such as fibres may be sought. This review provides a comprehensive comparison of the effectiveness of natural fibres and synthetic fibres in stabilising subgrade soils.
