This investigation analyzes the use of geosynthetics, specifically geogrids as reinforcement for granular bases within the structure of flexible pavement. In this way it seeks to determinate whether they are an economically and viable alternative maintaining the capacity of the proposed project. For this purpose two design alternatives under the same parameters of the initial design embodied in the Approved Technical File were made: the first alternative is a conventional design of a flexible pavement with 3 layers (Base, Subbase and Folder Asphalt); while the next alternative design consist strengthening the base layer with biaxial geogrids, in both cases the construction of the enhancement layer of subgrade is omitted because the characteristic CBR of each section are greater than 6%. Then for the alternative designs it is necessary to know the properties of geogrids, so a classification of these and their typical applications are shown. Strengthening mechanisms related to the use of geogrids in pavement structures and benefits of its application they were also described. Design methodologies that were used for this case and the investigations that led to obtain the factors involved in the design of geogrid reinforced sections were collected. With this information as a basis we proceeded to design pavement structures for 31 different sections subdivided based on their CBR. This allowed us a more complete analysis of the different factors that influence the final result obtained with the use of geogrids as reinforcement of granular bases; and find the conditions in which this alternative gives a better result of cost analysis for the project. Finally, the compilation of a technical specification model, developed according to the guidelines of the general specifications submitted by the MTC (MINISTRY OF TRANSPORT AND COMMUNICATIONS), which can serve for inclusion within the construction processes of other projects nationwide.
