The resistance of compacted soils is a mechanical property related to various parameters and that in many cases does directly depend on only dry density value as field control measures. In considerable soils this property is complex to specify and requires a more detailed study. In this work, the characterization of the resistance of a soil used in the construction road embankments is carried out, applying the tools of the Rational Methodology for the Analysis of Densification and Resistance of Compacted Geomaterials, with the purpose of knowing, through a novel approach, the mechanical response the soil related to different physical variables measurable during the construction process, among them, humidity and percentage of compaction. A CBR testing program was established as a resistance parameter, with specimens manufactured with their own conditions of humidity and compaction energy defined by the proposed factorial experiment. From the results, graphs of great engineering value were obtained, such as resistance maps for the interpretation of the mechanical manifestation of the material studied and the representation of a spectrum of design curves for the selection of the CBR following a weighting procedure and according to the possible hydration conditions associated with the project location.
