ABSTRACT

Chemical stabilization is one of the techniques used for soil improvement, using chemicals that change their characteristics. In Cuba an investigation is developed that part of creating a process for stabilizing soils using quaternary ammonium salts, known as ROCAMIX, which has as main advantages its economy and simplicity in its employment, while achieving increased resistance and reducing permeability in soils.

Article mode is presented in the quaternary salts produce the changes in soils, as well as modifications of the physical and mechanical properties of two types of stabilized soils with this system, comparing soil properties in their natural state and then improved, and the influence of the compaction energy and the evolution of the characteristics of the stabilized soils over time.
