2.5.2 METHODS OF STABILIZATION
 By mechanical stabilization
 By chemical stabilization
• Mechanical stabilization is the process whereby the stability of the soil is increased by blending the available soil with imported soil or aggregate so as to obtain a desired particle size distribution and by compacting the mixture to a desired density. Compaction at appropriate moisture content is itself a form of mechanical stabilization. Mechanical stabilization is achieved by intelligently blending locally occurring material so as to obtain a desired grading. It is that a dense, well-graded mass offers high resistance to lateral displacement under a load. If the well-graded is compacted, densification of the mass takes place. The mechanical strength of the mass is due to the internal friction and the cohesion. the internal friction is supplied by the coarser particle whereas cohesion is due to the clay friction.
The application of the principle of the mechanical stabilization is evident in the following specification;
• Soil-aggregate mixture
• Sand-clay mixture
• Stabilization of soil with soft aggregates
Chemical stabilization is a general term implying the use of chemicals such as lime, cement, sodium silicate, calcium chloride, bituminous material and resinous materials for bringing about stabilization. It is normally achieved by mixing the chemicals to the soil.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTIONSoil is the cheapest and the most widely used material in civil engineering project as foundation material either in its natural or improved form. It is highly heterogeneous and an isotopic in nature and existing with different engineering properties which can be influenced to some extend by the presence of sodium salts under the influences of water (Olawale, 2013). ...
