Sandy soils with considerable distresses such as low strength or high permeability may not be appropriate for use as a structural support. These soils may not bear loads and can cause damages to overlaying structures. A suitable ground improvement technique is needed to confront these problems. Using custom materials such as cement, lime and bitumen in soil stabilization project involves with some problems. Today with using new chemical materials such as enzymes and polymers a great change has been occurred in this field. Mixing chemical materials such as water soluble polymers is a new technical method to meet the requirements that is needed for sandy soils. The main aim of a ground improvement technique is increase in strength (especially bond strength) of the mixed soil. A comprehensive laboratory work was carried out in order to study engineering properties of mixed soils. Extensive research has been conducted using chemical additives. Chemical additives were prepared using water along with different percentages of polyvinyl acetate or acrylic resin emulsions. Experiments were performed in two series of laboratory works. One series using unconfined compression test and the other one direct shear test. Experiments in compressive tests were performed through columns filled with these soils. Experiments in direct shear tests were performed through boxes filled with these soils. The experimental results of two laboratory tests reveal that addition of polymer emulsion improves substantially the physical and mechanical properties of the mixed soil. The results were carefully investigated and finally show that the physical and mechanical properties of the mixed soil were enhanced.
