The present research "COMPARATIVE EVALUATION OF THE PHYSICAL CHARACTERISTICS AND MECHANICAL BEHAVIOR OF A HOT ASPHALTIC MIX ADDED WITH RECYCLED HIGH DENSITY POLYETHYLENE (HDPE) WITH RESPECT TO A PATTERN SAMPLE USING ASPHALTIC CEMENT PEN 85/100, WITH AGGREGATES FROM THE CUSCO REGION-2022" has as main objective to carry out a comparative analysis by means of tests of the physical characteristics and mechanical behavior (Density, Percentage of voids, stability, flow and moisture induced damage) of a conventional asphalt mix versus an asphalt mix added with recycled high density polyethylene (HDPE), using aggregates from the Cusco region and asphalt cement (PEN 85/100) from the COPESCO asphalt plant in the Cusco region. Quality control of the aggregates was carried out by means of standardized tests according to the Materials Testing Manual, the General Technical Specifications Manual for Road Construction EG-2013 and the National Building Regulation CE.010 of Urban Pavements, to then design a hot asphalt mix and determine its optimum asphalt content by means of the Marshall design for hot asphalt mixes, considering 6 percentages (4.0%, 4.5%, 5.0%, 5.5%, 6.0% and 6. Once the optimum asphalt cement content was determined, the optimum recycled high-density polyethylene (HDPE) content was determined using 6 percentages (1.0%, 2.0%, 3.0%, 4.0%, 5.0% and 6.0%) with respect to the total weight of the mixture. For a better comparative evaluation, we made additional hot asphalt mixtures with 4 percentages of asphalt cement (5.50%, 6.0%, 6.5% and 7.0%) adding recycled high density polyethylene (HDPE) in the 6 percentages already mentioned, taking into account that the 4 percentages of asphalt cement were taken based on the optimal percentage of asphalt cement determined (6.33%). Finally, a comparative analysis was made between the conventional hot mix asphalt and the hot mix asphalt added with recycled high-density polyethylene (HDPE) in its optimum percentages, concluding with respect to Marshall stability, there is an improvement of 123.845 kg and with respect to moisture-induced damage, there is an improvement of 5.7% in the percentage of TSR. However, with respect to the density, there is no increase in the percentage of TSR, so there would not be a higher durability performance, with respect to the percentage of voids, there is an increase of 0.405 gr/cm3 which is within the established parameter and with respect to the Marshall flow, there is an increase of 0.307 mm, so it does not meet the requirements of the Highway Manual "General Specifications for Construction EG-2013". In addition, it was also concluded that by adding recycled high-density polyethylene (HDPE) to asphalt mixtures of 5.5% and 6.0% of asphalt cement, they comply with some established requirements, but the asphalt mixtures of 6.5% and 7.0% of asphalt cement do not comply with the gravity verifications, so it was not considered in the comparisons.
