Diseño del pavimento de la vía rural del sitio limones vía huásimo - limones, parroquia limones, cantón Zapotillo, provincia de Loja

Abstract

This study aims to design the flexible pavement for the Huásimo-Limones road, a rural highway essential for the development of Limones Parish, Zapotillo Canton, Loja Province. Currently, the lack of proper road infrastructure limits the socioeconomic and tourism growth of the area. Through field studies and laboratory tests, soil conditions and traffic volume were analyzed to propose an efficient and long-lasting solution. The methodology included a geotechnical evaluation of the soil through grain size analysis, Atterberg limits, Modified Proctor, and CBR tests, which determined that the subgrade has regular resistance characteristics. Additionally, a vehicle count was conducted to classify traffic and assess its impact on pavement structure. Based on the AASHTO 93 design method, the final pavement structure consists of a 5 cm asphalt layer, a 10 cm granular base, and a 6.5 cm granular subbase. The findings of this research contribute to the optimization of rural road design, promoting sustainable development and improving the quality of life for residents.
