Soil Stabilization
Soil stabilization may be broadly defined as the alteration or preservation of one or more soil properties to improve the engineering characteristics and performance of a soil. Two common methods of stabilization are mechanical (compaction, inclusion of fibrous or other non-biodegradable materials or reinforcements) and additive (chemicals and emulsions to aid in binding and water retention). The goal is to modify the behavior of the existing soil as per its new use. The effectiveness of stabilization depends upon the ability to obtain uniformity in blending the various materials. Mixing in a stationary or traveling plant is a preferable way to achieve this. However, other means of mixing, such as scarifies, ploughs, disks, graders, and rotary mixers have been satisfactory. The method of soil stabilization is determined by the amount of stabilizing required and the conditions encountered on the project. An accurate soil description and classification is essential to the selection of the correct materials and procedures.
