Diseño geométrico de la alternativa vial Shuyo-Pinllopata en el tramo KM 20+000- 24+000 perteneciente a los cantones Pujili y Pangua de la provincia de Cotopaxi

Abstract

This document describes the technical process that must be followed in order to propose an appropriate geometric proposal for a road in a mountainous area. It is described step by step what is the methodology to follow the rules that were taken into account and the different variations and considerations that should be taken when performing a pre-feasible process. The first step is to carry out a current topographic survey of the area to be able to have details of contours and dimensions that will be considered in the geometric design of the road, the process that was taken in the present work was carried out with a Drone and taking photographs which are processed to obtain ortho referenced geo photos. In addition, the field work also includes the vehicle count in order to determine the TPDA that is the most important value to consider the different types of roads that the MTOP standard puts us in consideration, and the characteristics that each of them has in terms of speeds spokes and cant. Obtained the field data is processed to the office work, with the topography already digitized we can obtain a proposal of alignment that is considered as the horizontal alignment, which will also contain widths and corners in the curves respecting minimum radii and design speeds, of The same way having the same considerations for vertical and transverse design. Once verified that the design values meet the standard, we can quantify the cut and fill volumes in order to obtain a referential budget that would be an important value to approve or disapprove the pre-feasibility of the project.
