Mejoramiento vial del camino que une la comunidad 12 de octubre y la comunidad de Mochapata del cantón Santiago de quero provincia de Tungurahua

Abstract

The purpose of this project is to improve the living conditions of the population of the 12 de Octubre Community and the Mochapata Community in the Quero Canton of Tungurahua Province through a new highway layout. The objective of this project is to contribute to the economic development of these communities. The proposal is to develop a road with a new geometric layout that complies with current regulations and provides greater comfort and ease of transportation with greater safety to areas outside the canton and province. The project begins with the collection of field data, such as a topographic survey, which identifies the terrain characteristics and determines the surface area on which the project will be implemented. A vehicle traffic count is compiled, which identifies the types of vehicles currently on the road. This data is used to calculate the annual average daily traffic (ADTT) and future traffic, which determines the type of road to be built. Laboratory tests are conducted on soil samples taken in the field using test pits, which identify the physical and mechanical characteristics of the samples. Once all the preliminary data is obtained, the geometric design of the roadway is performed, including horizontal and vertical designs and calculations of the project's cross-section. The thicknesses of the granular layers and asphalt pavement of the roadway are also determined using AASHTO 93 standards. A hydraulic calculation is also performed, defining the cross sections of the lateral ditches and culverts. Once all the key project parameters are obtained, a unit price analysis is prepared to obtain the reference budget for the roadway
