Principles Of Soil Stabilization

The process of soil stabilization is a process of soil alteration and enhancement of the physical properties of the soil. For this process, effective soil stabilizer equipment is required. With soil stabilization, the shear strength of the soil can be increased and also the shrink swell properties of the soil can be controlled. This way, the loading bearing ability and capacity of the soil sub-grade can be improved, in order to provide increased support for the foundations and pavements.

Various models of soil stabilizers can be used for the stabilization process. The soil stabilizer can be used to treat various kinds of sub-grade materials, from clays to more granular soil materials. For proper treatment of the sub-grade materials, various additives are needed like: lime, cement and flu-ash. The soil stabilization process and the soil stabilizers are generally used around areas of uncertain and heavy use soils.

Soil stabilization can be used on small or big parking lots, roadways, airfields and in many other development projects where the sub-grade of the soil is not ready for construction. The benefits which can be gained from the soil stabilization process are:

• High soil resistance
• Plasticity reduction
• Pavement thickness reduction
• Effective compaction
• No need for excavation

In addition, there are also environmental benefits that can be gained through the process of soil stabilization. For example, if the roadways are treated with soil stabilization and appropriate soil stabilizers, road erosion can be prevented. As a result, the strength of roads and roadways is increased. Furthermore, the foundation of the roads increases its water resistance and resistance to washout.

Appropriate design and testing procedures are essential part of the soil stabilization process. The testing procedures are required for determining the type of additive that is going to be used for the stabilization process. An experienced geotechnical engineer is needed in the early stages of the soil stabilization process for successful stabilization results.

The process of soil stabilization involves several important steps in which appropriate soil stabilizer equipment is required. Depending on the soil type and additives, soil stabilization process can differ. It is somehow similar to he Full-Depth Reclamation process. At the beginning, a reclaiming and a soil stabilizer machine is used for soil pulverization. Then, an additive is placed on top of the pulverized material. The additive is mixed with the soil until desired levels of moisture and density are achieved. The newly formed soil base is graded with grader and then compacted with appropriate compaction machine. In the end, additional roadway materials are added.
