The modification was made through the dry process and the relationship of voids that characterizes the quality of an asphalt mixture in the modified and unmodified material was evaluated. The study was conducted by adding 5%, 15%, 25% and 35% slag percentages to the asphalt mix. The results obtained from integrating the special waste into the mixture indicate that this modification improves its mechanical properties and the performance of the materials when it is used in the mixture. Compared to the unmodified mixture the modified sample, it showed an increase of 30% in stability and 8% in flow, which predicts an improvement in the mechanical properties of the mixture in terms of increased resistance. On the other hand, the volumetric properties comply with the standard requirements, and the rigidity modulus test, that determined the behavior of the pavement on site,also increased, which demonstrates the advantages of using this slag residue in the asphalt mix.OpenAccessAsfaltoDesechos sólidos
