Rediseño geométrico y del pavimento de los tramos: Playa – Rayoloma, Rayoloma – Tuglín y Tuglín – Yacubamba con una longitud de 5.17 km, del cantón Pujilí, provincia de Cotopaxi

Abstract

Given the need for an improvement in the existing road infrastructure in the communities of La Playa, Rayoloma, Tuglín and Yacubamba, the proposal of this technical project arises. It began with a field inspection and the current state of the sections of road, the different characteristics of the terrain and the most relevant points or sites were identified, which served as a basis for carrying out the topographic survey itself, which was carried out with the help of a drone and RTK as precision equipment. The vehicle count was carried out manually and the type of road necessary to supply the projected vehicular flow was determined, obtaining a class III collector road and after that, the geometric redesign of the road sections was carried out using the parameters established by the regulations. MOP 2003. Through the soil studies carried out with samples extracted from the sections of the road in accordance with the specifications of the standards, the physical and mechanical properties of the soil were identified, which allowed the design of a pavement structure with thicknesses of base, subbase and suitable asphalt folder to guarantee functionality and safety. This design was based on the AASTHO 93 standard. In addition, the design of minor drainage works (ditches) and signaling, required for this project, was carried out. Finally, a referential budget was established based on updated prices and establishing the items, volumes of work and necessary technical specifications.
