Stabilizationof soil  is treatment of the'soil which renders it more stable. In engineering construction,stabilization refers to addition and mixing an admixture known to be stabilizing agent with soil before compaction is carried out, so as to altering the chemical make up of soil resulting in more stable material.Stabilization may be applied in place to a soil in its natural position or as it is placed in a fill. Also, stabilization may be applied in a plant and then transported to the job site for placement and compaction.

Cement-soil Stabilization is another technique, the other answers mentioned are also true but this is another technique for your information...Where Portland cement can be used to stabilize and strengthen certain type of soils. In this regard granular soils are very effective for cement stabilization. The required quantity of portland cement is spread over the soil uniformly which is to be stabilized, followed by mixing it into the soil, preferably with a pulverizer-type machine, to the specified depth, followed by fine grading ar@ compaction. If the moisture content of the soil is low, it will be necessary to sprinkle the surface with water during the process of operation.

Stabilization of soil with lime,  Because  Lime in its hydrated form rapidly exchanges cation leading to flocculation and agglomeration,provided it is intimately mixed with the soil. The clay type soil will then behave more like a silt type soil than clay type soil. This transformation starts within a hour of mixing and significant changes are realised within a very few days depending upon the plasticity index of the soil and the amount of lime used.

Blending and Mixing Soils - this is one technique by which soil stabilization is achieved.

 If the soils found are to be heterogeneous or different in their original states in the pit itself, it should be mixed thoroughly before being used in the fill. This can be accomplished during excavation itself by using equipment such as a power shovel or a deep-cutting belt loader to exacavate through several layers in one operation. After these materials is placed on fill, further blending can be carried out by several passes with a disk harrow.

I hope u got the answer for your question.....
