Diseño geométrico de la vía que conecta las comunidades Illapa – Chaquiragra de las parroquias Santa Fe y Asunción de los cantones Guaranda y Chimbo, provincia de Bolívar

Abstract

The purpose of this project is to solve the road problems that exist between the Illapa and Chaquiragra communities, in order to encourage their agricultural production, reducing the travel time for their commercialization and to improve the socioeconomic areas of the study area. The topographic survey was carried out to know the physical characteristics of the terrain with the technological help of a total station, taking into consideration a topographic strip of 50 meters on both sides of the road. Regarding the vehicular flow, it was determined by means of a manual count of 12 hours a day for 7 days, a method that helped to calculate the Annual Daily Average Traffic (TPDA) with a future projection of 20 years. Test pits called test pits were excavated to take soil samples every 500 meters along the road, which resulted in 8 types of samples, which were later transferred to the laboratories for their respective drying and with for this, carry out the different soil tests necessary to know their physical and mechanical characteristics. The geometric design of the road was carried out based on the current regulations of the Ministry of Transport and Public Works (MTOP - 2003) and for the design of the structural package the AASHTO - 93 method was used. The referential budget was determined through the analysis of unit prices, emphasizing the price of labor, materials and equipment for the year 2023.
