This article presents the efficiency of using concrete mixtures replacing 75% of gravel by electric arc furnace slag, and simultaneously 20%, 30% and 40% of sand by recycled ground glass. The selected replacements correspond to the results obtained by the authors in previous research. The materials were analysed physically, chemically, and mechanically. The mixtures were studied in compression and bending in samples of cylinders, and beams loaded in the thirds of the section, respectively. Through scanning electron microscope analysis, the adherence between aggregates and cement was studied, and X-ray diffraction analysis determined how the material crystallized, and the species found within the mixtures. The study contrasted the results obtained with the Colombian regulations described in article 500-13 of the specifications of the Instituto Nacional de Vías" (2012) and design manual of concrete pavements by "Instituto Colombiano de Productores de Concreto" and "Instituto Nacional de Vías" (2008). The results validated the use of the mixtures in the construction of rigid pavements in the department of Boyacá, Colombia.
