    As the days go by, the problem of environmental pollution is a critical problem for society, so it has become necessary to create new techniques for recycling products that daily increase in the different deposits of our country, such as tires that are transferred to deposits for their final disposal, which do not have the technique for their elimination, resulting in a negative environmental impact, and can be used for the construction of roads. The purpose of this research is to add crushed vulcanized rubber in cold asphalt mixtures by elaborating 3 briquettes for the percentages of 0, 3, 6, 9, 12 and 15 percent of rubber addition, with stone aggregate obtained from the Herrera quarry in the city of Latacunga, applying the Marshall method to obtain parameters that will later allow us to design a flexible pavement structure. Once the briquettes were made, we proceeded to test the stability and flow, giving the optimum percentage for the sample without rubber of 6.03, and with crushed vulcanized rubber 3, 6, 9, 12 and 15 percent, with optimum percentages of 6.2, 6, 6.13, 6.03, and 5.9 percent respectively, indicating that as the percentage of crushed vulcanized rubber increases, the stability decreases but the flow increases, that is to say, the sample remains elastic. For the design of a flexible pavement structure, the thickness of the asphalt slab is 5 cm, for base of 10 cm and subbase of 10 cm.
