			ABSTRACT

Currently, existing soil classifications in Geotechnics and affine areas correspond to the general behavior of different soil groups. These classifications sometimes are superficial and could lead to ambiguity due, for example, to the way for obtaining the parameters being used to classify such a soils, which are, frequently, empirical. Indeed, one classification can be attributed to soils with similar characteristics, but different mineralogical contents. This, in turn, lead to behavior differences, difficult to detect with the soils classification. Because of the above, in this work, soil index properties evaluation, both, expansive and CaO treated are reported. In both cases mineralogical characterization were done via, among others, X-Ray Diffraction, Scanning Electronic Microscopy, and Thermal Analysis.

Keywords: Mineralogical characterization, stabilized soils, expansive soil, lime, lime characterization, treated soils, characterization techniques, calcite.
