The method of stabilisation is frequently employed to improve the engineering characteristics that cohesive or clay soils, sometimes known as soft soils, normally exhibit. Stabilisation is the most common method of improving these qualities, which include low strength, swelling and shrinkage characteristics, etc. The purpose of this investigation was to ascertain whether soft soil that had been combined with an alkaline solution was effective in stabilising the soil. It provides not only with an answer for the proper use of alkaline solutions, but also with a material that works well as a subgrade while constructing pavement.Because natural fibres are affordable, easily obtainable locally, and environmentally friendly, using them in civil engineering to enhance the properties of the soil is advantageous. The natural fibre reinforcement significantly enhances the soil's shear strength, load bearing capacity, and other engineering characteristics.
