The purpose of this research project was to evaluate the triaxial geogrids, as reinforcement elements in the Subgrade - Subbase interface of the flexible pavement structure, with the aim of optimizing pavement thicknesses, increasing the support capacity of the subgrade and prolonging the useful life of pavement. This paper presents the application of a design methodology for the use of triaxial geogrids, with the technical specifications for the applied design of geogrids inflexible pavements in Peru. The design methodology is focused on the investigations of Dr. J.P. Giroud and Dr. Jie Han, who present a generated confinement effect, between the geogrids and the layer of material on the subgrade. The floors when subjected to tire loads tend to deform, generating rutting on the running surface. With the presence of geogrids in the ground, this rutting is reduced exponentially (Giroud & Han, 2005). For the proposed methodology an application example is developed for the reinforced design, of a paved base, with triaxial geogrid and another without reinforcement. For this example, data was collected with the aid of the vehicle classification formats of the MTC, visual inspection of the road for the evaluation of the pavement condition index (PCI) and laboratory tests; which was executed along the approximately 2.3 km, in which it was observed that the PCI of the section is 21%, this means that the service level of the road is bad, that is, it requires immediate intervention. Through this methodology the use of geogrids implied a decrease in thickness of 33.33%, it should be noted that it must be taken into account that each design will vary according to the project to be executed, therefore, it will depend on the characteristics of the soil, vehicular traffic and reinforcement (Type of geogrid) used.
