        abstract = {Soft soils, such as clay and cohesive soils, exhibit undesirable engineering properties, including low strength, swelling, and shrinkage. This study aims to enhance these properties through stabilization techniques combining alkaline solutions and natural fibers. Alkaline solutions, like NaOH, improve soil properties, while sisal fibers reinforce and increase shear strength, load-bearing capacity, and other engineering characteristics. Experimental investigations focused on optimal dosages of alkaline solutions, fly ash (20% by soil weight), and sisal fibers (up to 3.0 cm length, various percentages). Results showed significant improvements in California Bearing Ratio (CBR), unconfined compressive strength (UCC), and shear values of stabilized soils. The study also highlighted the impact of fiber and chemical combinations on stress-strain behavior, moisture content, and dry density. Optimal outcomes were achieved with 30mm sisal fibers treated with turpentine oil for durability. A comparative analysis indicated superior performance of chemically stabilized and reinforced soils over untreated soils. This eco-friendly and cost-effective methodology offers substantial benefits for subgrade and embankment applications.},
