Different processes of soil stabilization

Soil stabilization is the process in which the enduring physical and chemical properties are altered to get the best results while construction. This process plays a vital role in enhancing the corporeal properties of the soil. Stabilization further elevates the shear strength of the soil and controls the shrink-swell characteristics of the soil.

Stabilization is carried on so as to treat diversity of sub-grade resources varying from expansive clays to granular materials. Stabilization is achieved with a diverse range of chemical additives comprising lime, fly-ash, and Portland cement. The appropriate design and testing is a noteworthy constituent for any stabilization project.

In this process, air entraining cements and normal cements are used. Regardless of the texture of the soil, the every kind of soil gets amalgamated with Portland cement in a refined manner.

There are diversified processes by which soil can be stabilized:

·          Stabilization with lime

·          Stabilization with cement

·          CMS

·          Stabilization with bitumen

Lime stabilisation can be used to increase the workability and load-bearing characteristics of the soil. Quick lime is one of the major sources through which the quality of the wet soil is improved. Lime substantially improves soil resilient modulus value. Pulverization and mixing is used to combine the lime and the soil.

Cement stabilization further increases the concreteness and sturdiness of the place where the process is carried on. Cement stabilization is done so that the surfaced area does not encounter any complexity in long run prospects.

CMS not just provides a permanent modification of the soil, but it further improves the strength, plasticity sturdiness and shrinkage limit properties. There is no requirement of bringing special tools and equipments for stabilizing the soil with CMS, rather the equipments that are required while lime stabilization is adequate to get good results.

Stabilization with bitumen is required for highway pavements so as to increase the efficiency in the soil stabilization procedure.

Overall, these were some of the major processes by which soil stabilization can be done.
