In the construction of pavement, structures are determined by granular materials treated with asphalt emulsion in the pavements, in the structure of the pavements is very common to find unsuitable materials which generate both in the constructive and economic environment various types of inconveniences. The pavement structures are made up of different layers, each of which fulfills a certain function. The treatment of the material helps to reduce the cost of the pavement structures, obtaining improvements in their behavior and economic results in the construction of the same. What is intended in this research is the treatment of the selected material combined with asphalt emulsion, therefore, that can be used both as a base or sub-base within the pavement structures. For the analysis of the behavior of the selected material, the San José and AGRE S.A quarries were taken, in order to determine their own characteristic variants and thus demonstrate whether stated material meets the technical specifications for incorporation in the construction of the pavement structures.
