Resumen

This research was presented in response to the need to improve the operational condition of a 12-km stretch of road located on the Casagrande-Roma-Chiclín highway. This was due to a high degree of deterioration in the surface and structural lay-ers of the pavement comprising the section. Therefore, various studies were conducted, highlighting the different require-ments and procedures that must be followed to correctly implement the AASHTO 93 method. The overall objective was to design a flexible pavement using the AASHTO 93 method to improve the operational condition of the Casagrande-Roma-Chiclín section in the province of Ascope, La Libertad, thus contributing to road safety, transportation efficiency, and the economic development of the region. A quantitative methodology was employed, requiring data collection from traffic studies, soil studies, precipitation studies, and the development of the pavement design for the roadway. The structural design proposed a structure composed of a 10 cm surface layer, a 25 cm granular base, and a 30 cm subbase. This design proposal was presented with the goal of im-proving the roadway's operational condition by using the AASHTO 93 method for design. © LEIRD 2025.All rights reserved.
