“…As the fiber content increases, it affects the contact area between the fiber and the soil, affecting the cohesion and friction between the fiber and the soil. Similar observations were made by Zafar et al [59] on natural and synthetic fiber-reinforced soil. Therefore, when the fiber content was increased from 1% to 2%, a larger contact area occurred in the soil and improved mechanical properties.…”

The aim of this study is to investigate the bearing capacity-settlement behavior of strip footing settling on sand soil randomly reinforced with glass fiber, basalt fiber, macromesh fiber, and four different hybrid fiber additives in which these fibers are used together. Model tests were carried out in the laboratory on the strip footing and placed on the unreinforced and reinforced sand with different fibers. In the study, model tests were carried out on seven types of randomly reinforced soils by using glass, basalt, macrame, and mixtures of these fibers as reinforcement. In the model tests, two different fiber contents, 1% and 2%, and two different fiber lengths, 24 mm and 48 mm, were used. Tests were carried out with Dr = 30% and 50% relative density, and reinforcement depths 1B, 2B, and 3B were selected. In addition, the photographs taken during the test were analyzed with the particle image velocimetry (PIV) method and the displacements on the soil were examined. As a result of the reinforced and unreinforced model tests, the highest ultimate bearing capacity was measured as 680 kPa from the tests with Dr = 50% relative density, 48 mm length, 2% contents, and 3B depth macromesh fiber reinforced. In hybrid fibers, the highest ultimate bearing capacity was measured as 495 kPa, with Dr = 50% relative density, 48 mm length, 2% contents, and 2D depth micromesh and basalt fiber-reinforced tests. In the reinforced tests, it was concluded that the most effective fiber on bearing capacity is macromesh fiber. It can be seen that in the PIV analysis, as the fiber additive increased, the settlements made by the foundation decreased under the same pressure. It has also been observed that adding reinforcement to the soil transfers the stresses occurring in the soil to a wider area.

“…Several materials and techniques have been used in soil stabilization such as cement stabilization [15,16], lime stabilization [5,6,17], bituminous stabilization [18,19], electrical stabilization [20,21], grouting [22,23], fly ash stabilization [24,25], burned sludge stabilization [26][27][28], sisal fiber stabilization [29,30], polypropylene stabilization [31,32], and compaction [33]. These materials and techniques were used to increase the shear strength properties, as well as to reduce settlement, compressibility, and expansion of the soils.…”

Construction of earth fill dams offers a cost-effective solution for various purposes. However, their susceptibility to internal soil erosion, known as piping, poses a significant risk of structural failure and resultant loss of life and property. Soil stabilization emerges as a practical technique to fortify these dams against such threats. This study investigated the impact of lime on the internal erosion properties of clay soils, focusing on CH and ML soil types. Specimens of different lime content were prepared and remolded at 95% relative compaction and optimum moisture content. Hole Erosion tests at varying lime concentrations and curing durations were adapted to conduct the investigation. This investigation aims to optimize lime content and curing time for cohesive soil stabilization against internal erosion. Findings revealed that 2% and 5% of quicklime, by dry weight of the soil, effectively stabilized CH and ML soils, respectively, against internal erosion, with a two-day curing period proving optimal. Furthermore, the addition of lime significantly enhanced erosion rate index and critical shear strength in clay soil, underscoring its efficacy in soil stabilization efforts.

“…When constructing roads, bridges, and other infrastructures on expansive soil, which expands and contracts depending on the weather, civil engineers face many challenges. Over 20% of India is made up of black cotton soils [2][3][4][5]. Variations in the moisture content cause these soils to exhibit considerable differences in swelling, compressibility, and shear strength, ultimately resulting in structural failure.…”

“…Soil stabilisation is the process of transforming unconsolidated unstable soil into a more rigid stable medium that can support constructed structures, change permeability, alter subsurface movement, or immobilise pollution by mineral precipitation. Multiple materials and techniques are studied and employed in soil stabilisation to make it more suitable for construction purposes [3,8,9].…”

“…All these stabilisers were added in different dosages and most of the research works involved obtaining the optimum dosage with reference to the soil selected. Some of the studies utilised both stabiliser and a fibre to increase the strength [3]. Behnood [6] conveyed that any cementitious materials, such as Portland cement or lime, can be employed to stabilise soil, but the resulting product takes on the characteristics of both the soil and the stabilisation reagent.…”

Soil, a naturally occurring resource, is increasingly used as a construction material. Stabilisation strengthens soil, which is weak as an engineering material. Stabilising soil changes its physical qualities, enhancing its strength. Soil stabilisation increases the shear strength and load-bearing capacity. Soil stabilisation refers to any endeavour to change natural soil for engineering purposes using physical, chemical, mechanical, or biological methods, or a mix of these. Strengthening road pavements includes improving the load-bearing capacity, tensile strength, and performance of unstable subsoils, sands, and waste materials. Due to market demands and scientific advances, the number of soil-stabilising additives has increased. These innovative stabilisers include reinforcing fibres, calcium chloride, sodium chloride, and cross-linking water-based styrene acrylic polymers, which are geopolymers that boost the load-bearing capacity and tensile strength of soil. Many materials are being explored for soil stabilisation. In this article, the authors investigated the direction of soil stabilisation research. Scientometric analysis identifies stabilisation challenges and research trends in the field. This study analysed research patterns by countries, authors, institutions, keywords, and journals from 1959 to 2023; in 2021, 150 articles were published, which was the highest number in a year. Citations peaked at 3084 in 2022. With 253 publications and 3084 citations, India was the most productive country. Iran and France published the fewest, 34 and 33, respectively. The Islamic Azad University and the National Institute of Technology had the fewest published articles with 17 articles. This work can help track soil stabilisation research and will serve as an information document for future research.
