This research proposes to optimize the thicknesses of the bases treated with cement through the structural modeling in La Costanera highway, Piura, with the purpose of reducing investment costs while providing an adequate structure for the requirements of the road. The improvement proposals considered will be based on the design of the structures, in the first instance by the AASHTO 93 methodology and later verified by the structural modeling through the Rational Method. For the development of the design methodologies, the scenarios for each section of the roadway were determined using the basic studies required: traffic and soil studies. Determining the number of vehicles circulating, the capacity and soil characteristics for each section, the AASHTO 93 method is applied, adapted by the Manual de Carreteras, Suelos and Pavimentos Section (RD Nº 10-2014-MTC/14), in the same way the information requested by the WinDEPAV program that utilizes the Rational Method is loaded. The results obtained by the AASHTO 93 method suggests an analysis of the simplicity of the method in its way of validating the proposed structure and the empirical parameters it uses. It is precisely these structures that are verified with the WinDEPAV software, which allows knowing the tensile and compressive stresses in each layer that makes up the pavement, which is translated into a cumulative damage factor per layer. This result allows evaluating the behavior of the cement-treated base layer in the structure in order to recalculate the appropriate thicknesses for a better structural behavior and, in turn, reduce investment costs by 33%.
