The purpose of this research project was to evaluate the use of the geocomposite (Triaxial geogrid and HDPE geomembrane), as reinforcement in the subgrade-subbase interface of a flexible pavement structure. To do this, a design of a pavement structure reinforced with geocomposite is proposed in a section of Av. Prolongación Defensores del Morro-Chorrillos that allows increasing the support capacity of the subgrade, optimizing the thicknesses in the granular layers, and prolonging the life useful of the pavement. For this purpose, the design of a conventional pavement structure and another reinforced with geocomposite were proposed to compare and choose the most optimal design. Data collection was carried out using the MTC vehicle classification formats, visual inspection of the road, soil mechanics study and experimental analysis. After analyzing the data collected, it was determined that the PCI of the section under study is 21%, this means that the level of service of the road is bad and needs intervention. Therefore, the design of three flexible pavement alternatives was carried out: the first alternative is a conventional unreinforced section, while the other two alternatives consist of sections reinforced with triaxial geogrid and HDPE geomembrane. The results obtained show that the pavement reinforced with geocomposite and designed by the Giroud-Han method obtained a 47.62% reduction in the thickness of the flexible pavement structure with respect to the pavement designed by the AASHTO 93 method. Finally, after an economic analysis of the flexible pavement design alternatives, it is concluded that the cost of pavement reinforced with geocomposite is 5.07% lower than that of traditional pavement (AASHTO 93).
