Soft soil is one of the major challenges in engineering projects. Improving soil’s engineering properties is called soil stabilization. This paper focuses on soil stabilization materials and methods thereby soils and related materials and structures are made stronger and more durable. Soil stabilization involves the using of stabilizing agents, binder materials, in soft soils to improve its geotechnical properties such as bearing capacity, compressibility, shear strength, permeability and durability. Using of stabilized soils in place with natural aggregates and structure of soil has great environmental and economic advantages. Investigation for selection the best soil stabilizers to overcome geotechnical problems occur by the weak soils is one of the main concerns to attain the required soil engineering parameters by considering the cost, efficiency and the effect to the environment. This paper reviews the application of different materials and additives used in soil improvement in geotechnical projects in Iran and present their effects on soil engineering parameters.
