Diseño geométrico y estructural de la vía que une el anillo vial con el sector San Isidro, desde la abscisa 0+000 hasta la 4+000, perteneciente al barrio Rumipamba de Navas, parroquia San Miguel del cantón Salcedo, provincia de Cotopaxi

Abstract

This project focuses on the geometric and structural design of a road in the rural neighborhood of Rumipamba de Navas, Salcedo canton, Ecuador. The need for this project arises from the poor current condition of the road, which does not comply with the widths and requirements established by current Ecuadorian road standards. This situation limits the mobility of the inhabitants and the accessibility to the sector. For the geometric design of the road, a complete topographic study was carried out, thus determining the orographic characteristics and the extension of the project. Additionally, a traffic study projected for 20 years was carried out, allowing the geometric characteristics of the road to be established, such as road width, curvature radii and slopes. Regarding the structural design of the flexible pavement, soil tests were carried out, the AASHTO 93 method was used to determine the optimal structure of the wearing layer, guaranteeing adequate resistance and durability of the pavement against the expected vehicular loads. Finally, a price analysis was carried out to determine a reference budget and estimate the investment required for the project. The design of this new road in the Rumipamba de Navas rural neighborhood will improve the mobility of the inhabitants and the accessibility to the sector. The project has been developed following current Ecuadorian road regulations. Obtaining as a result a future TPDA of 726 vehicles per day, a 10 m wide road including shoulders and ditches, finally the final structure of this consists of 15 cm of subbase, 15 cm of base and 5 cm of wearing layer.
