Soft soil having a low bearing capacity is found in many parts of the world and construction on soft soil is a challenge. To overcome the situation, the soil needs to be stabilized with some external material like geosynthetic, fly ash and rice husk. Geosynthetics materials are tremendous materials used to solve many civil engineering problems. Fly ash is a byproduct produced by burning of coal and is available in various thermal power plant as a waste material. Disposal of fly ash is also a problem but in one area where it can be used is soil stabilization. A comprehensive review of published literature on the use of geosynthetic and fly ash to stabilize and enhance the strength of soil was carried out. The effect of using geosynthetic material and fly ash was investigated on the properties of soil like Optimum Moisture Content, Maximum Dry Density, California bearing ratio, unconfined compressive strength and compaction behavior of the soft soil.
