The purpose of this thesis was to perform a comparative analysis of the stability, flow, percentage of air voids (physical and mechanical properties) and costs in material resources, of a Traditional Hot Asphalt Mix made with asphalt 85-100 PEN and a Optimal percentage of lime, compared to a Hot Asphalt Mixture made with asphalt modified with Styrene-Butadiene-Styrene (SBS) polymer brand (BETUTEC 60T), this asphalt mixture was given the nomenclature: MAC. POLYMER. It was necessary the manufacture of a third asphalt mix, called Traditional Hot Asphalt Mix made with asphalt 85-100 PEN, since depending on the physicalmechanical properties of this asphalt mix, a better comparative analysis of the results obtained was made. For the elaboration of these three types of asphalt mixtures the same gradation and the same stone aggregates were used, the coarse aggregate came from the quarry of Morro Blanco (Pisac), for the fine aggregate was used material from two quarries, Morro Blanco and Piñipampa (Andahuaylillas), the latter marketed by the company Super Mix. The research work sought to improve the physical - mechanical properties of the traditional hot asphalt mix made with asphalt 85-100 PEN, through the substitution in weight of percentages of aggregate by lime, in which the percentage of substitution was sought which provides better results to the physical mechanical properties of the traditional hot asphalt mix, this percentage of substitution that provided better results to the physical and mechanical properties, was denominated, Optimal Percentage of Cal. This comparative analysis of the physico-mechanical properties was carried out using the “Marshall“ asphalt hot mix design method, whose objective is to determine the optimum percentage of asphalt for a specific combination of aggregates; for which specimens of asphalt hot mix were manufactured; the same ones that are composed of different percentages of asphalt (5, 5.5, 6, 6.5, 7%) and Cal (1, 1.5, 2, 2.5, 3%), these specimens were subjected to laboratory tests to determine their physical properties (percentage of air voids, density) and mechanical (stability, flow). Based on these results and the regulations of the road manual “General Technical Specifications for Construction EG - 2013“ of the Ministry of Transport and Communications of Peru, a percentage of substitution by weight of aggregate per optimum lime of 2.5% was obtained in a Mixture Traditional hot asphalt made with asphalt 85-100 PEN. It was possible to compare the physical-mechanical properties studied, arriving at the following conclusion: The traditional hot asphalt mixture made with asphalt 85-100 PEN and an optimum percentage of lime of 2.5% provides greater benefits and lower costs in its material resources than the Hot asphalt mix made with asphalt modified with Styrene-Butadiene-Styrene (SBS) brand polymer (BETUTEC 60T).
