Rediseño geométrico y diseño del pavimento flexible de la vía Bellavista Jesús del Gran Poder del cantón Tisaleo provincia de Tungurahua

Abstract

The preparation of this Technical Project responds to the need to provide safe and comfortable mobility to the inhabitants of the sector who are dedicated to agriculture and livestock. Furthermore, the objective is to reduce travel times and promote the economic and social development of the intervened areas and their surroundings. During the investigation, the topographic survey was carried out using the high-precision RTK GPS and a drone to capture orthophotos, delimiting the 50m topographic strip on each side of the road and a study length of 4,091km. In addition, a traffic study was carried out by manually counting vehicles in the project area, in which it was projected that by the year 2044, the TPDA will be 473 vehicles per day and the number of equivalent axles will be 48,606, Classifying a class III road, the geometric design was carried out in accordance with the Ecuadorian regulations MTOP 2003 and NEVI - 2012. For the design of the pavement, a soil study was carried out in the laboratory, resulting in a design CBR of 15 percent. Applying the AASHTO-93 Method, thicknesses of 5 cm were established for the asphalt layer, 15 cm for the class 3 granular base and 15 cm for the class 3 granular subbase. Finally, a reference budget for the project was developed with a value of $1,455,549.94, detailing items and volumes of work, providing a clear understanding of the resources necessary for the execution of the proposal.
