    Currently worldwide environmental pollution has been increasing due to poor waste management, one of the main pollutants are polymers found in materials such as plastics and rubber. In this work, the conventional asphalt mix was modified with the implementation of non-biodegradable recycled material, improving some of the mechanical properties of asphalt, so as to promote the reuse of commonly consumed materials. Conventional asphalt briquettes and asphalt modified with PET (Polyethylene Terephthalate) recycled material and modified with Nitrile Rubber were made in order to analyze their mechanical properties and performance compared to conventional asphalt mixtures, giving these materials a new use. . The behavior of a modified asphalt mixture with the addition of 5, 10, 15 and 20 percent of PET was analyzed, in addition to one modified with 2, 3, 4 and 5 percent of Nitrile Rubber for which ASTM D 1559 and AASHTO T 225; 36 samples were prepared, of which 12 correspond to conventional asphalt mixtures and 24 to modified mixtures, once analyzed the optimum percentage of asphalt and polymer was established, finally through a comparative analysis of the results it was determined that the addition of these materials Several parameters of the asphalt mix improve compared to the conventional one, thus being the sample added with nitrile rubber the best option.
