Σύνοψη

Most of the earth's land surface is covered with a layer of granular sediments known as soil which because of its universal availability and its low cost is widely used an engineering material.
Usually the engineering properties of soil in its natural state are quite unfavourable, therefore some method must be employed for improving them. This method in known as soil stabilization. Therefore soil stabilization is the term used to describe the alteration of the engineering properties of soil so as to meet specific engineering requirements.
Although stablilization is still most often considered in relation to road construction, the range of application has increased with the increased of knowledge of techniques and nowdays it is used in nearly all civil engineering projects where soil is employed.
The simplest stabilization method is mechanical stabilization usually achieved by compaction and drainage; if a loose soil is tamped down or if water is drained out of a wet soil the soil will became stronger. Greater strength still may be obtained by improvement of the gradation of the soil
maintained by a proper selection of the fine material.
Other methods employed are stabilization by the use of additives such as cement, lime, bitumen by heart treatment and by forced drainage achieved by the use of electric potentials.
It must be stated though that specification and control is required in every method used I that is why before and after the application of any stabilization method several tests must be carried out.
Generally stabilization is of great application since it is not always possible to use other alternatives such as the relocation or redesign of the project.
