Diseño geométrico de la vía Arenillas – intersección ingreso La Cuca, cantón Arenillas

Abstract

This project aims to solve the need that arises on the road that connects Arenillas city with the entrance to the La Cuca parish. Through a field study it can be confirmed that the lack of road infrastructure that exists in this area affects the socioeconomic development of the population. According to the analysis of the road, a visual inspection was carried out in which it was found that there is an irregularity in the road, this constantly affects agriculture, since in wintertime access to the area is made with greater difficulty. For the geometric development that was carried out on the road, a topographic survey was carried out with an RTK type, a vehicle capacity study using the manual vehicle counting methodology to determine the volume of traffic. The tests that were carried out were the limits of Atterberg, granulometry, Proctor and CBR. This helped us determine the type of soil that is present on the road. The results gave us that a clayey silt soil is present with a resistance that characterizes the subgrade. as very bad, this indicates that soil improvement must be carried out. To carry out this study, the Civil 3D tool was used, with the purpose of obtaining the geometric design of the road and thus determining the cut and fill cubing. In addition, the quantities of material of the road structure that consists of the subgrade, subbase, base and rolling surface, in this way the respective work schedule was carried out.
