Mejoramiento de la vía Cotundo-Comunidad 5 de Octubre de la parroquia Cotundo, cantón Archidona, provincia de Napo, con la implementación de sistemas alternativos de drenaje

Abstract

The present technical research project has a proposal to carry out the road study, proposing an improvement to existing geometry by adding drainage systems. From the data obtained during the topographic survey, the improvement of the geometric design was made, establishing suitable parameters such as design speed, radius of curvatures, slopes, peraltes, etc. By means of the study of soils it was possible to verify that the soil is of silty clay type with high moisture content and a CBR of 3.95%, reason why it was proceeded to make the improvement of the subgrade with granular material of the mine May 20 located 2 km from the site of road implantation, the relevant tests were carried out as a result of a CBR value of 9%, which will provide greater soil resistance and logically a reduction in the thickness of the upper layers. As an alternative drainage system, drainage ditches, a drainage mantle with a fishbone, and the placement of geotextiles were proposed in order to provide greater stability and durability of the road construction, ensuring that the population can make use of it without any inconvenience.
