Propuesta técnica de rediseño vial para el tramo rural de la vía al Quemado – Santa Rosa abscisa 0+000 hasta 3+187 a partir del análisis topográfico, geotécnico y de tránsito

Abstract

This project arises from the evident need to improve the conditions of a rural road located in the Al Quemado sector, in the canton of Santa Rosa, whose current state, marked by geometric deficiencies, low structural capacity, and progressive deterioration, limits mobility, particularly for agricultural transport, and affects the socioeconomic development of the area. The main objective was to design an alternative road layout adapted to the actual terrain conditions and existing traffic volume, ensuring greater safety, functionality, and durability. To achieve this, technical studies were conducted, including topographic surveying, traffic counts, and laboratory tests on soil samples, which allowed for an accurate characterization of the current conditions and the definition of design parameters. Based on these results, a new geometric design was proposed with an appropriate design speed, adjusted slopes and curves, as well as a flexible pavement structure tailored to the bearing capacity of the subgrade and projected demand. The project development followed national regulations (NEVI-12), the AASHTO 93 methodology, and used tools such as AutoCAD Civil 3D for precise planning. Altogether, this proposal aims to improve the area’s connectivity, facilitate the transport of agricultural products, and contribute to the well-being of local residents.
