Collapsible soils are unsaturated soils which present a potential for large strains and a complete change to the whole particle structure after wetting with or without loading. These soils are characterized with loose structures composed of silt to fine-sand-size particles.The objective of this experimental study is to illustrate that the resistance of collapsible soil can be improved. This study demonstrates that it is possible to minimize the collapsible potential Cp to an acceptable level after chemical treatment with salt (sodium chloride NaCl) at different concentrations (0.5, 1.0, 1.5 and 2.0 mole/liter) and at different compaction energies. The method used in this study is based on oedometric tests with variable normal stresses.
