Diseño geométrico y estructural de una vía que une el sector de Calgua con el centro de transferencia perteneciente a la parroquia Augusto Nicolas Martinez, cantón Ambato, provincia de Tungurahua

Abstract

The geometric road design proposes to unite the Calgua sector belonging to the Augusto Nicolás Martínez parish with the Ambato Transfer Center with the purpose of solving the problems of the sector, such as the shortage of road works, the difficult access to services such as health, education and human mobility, all as a consequence of inadequate road infrastructure. This project began with the socialization of the inhabitants of the Calgua sector. The area where the construction of the road is proposed was visited, and the topographic survey was carried out for two days with GPS RTK equipment. The Annual Average Daily Traffic (TPDA) was determined during a period of 7 days. The extraction of soil samples was carried out by means of the open pit method to carry out the granulometry, Atterberg limits, modified Proctor and CBR tests. Regarding the geometric design of the road, the MOP 2003 standard was used and the AASHTO-93 standard was used for the structural design of the flexible pavement, in addition to allowing a referential budget for the project to be made. Finally, TPDA results of 186 veh/day, a type of SM soil (clay sand), a design CBR of 9.7 percent, a road width of 11.20 m and a flexible pavement structural package of 40 cm were obtained, in addition to a referential budget of one million six hundred sixtyeight thousand eight hundred sixty-one dollars, 34/100 cents
