Evaluación de la infraestructura vial actual de la av. Cotopaxi y Rio Cutuchi de 2,46 km de longitud perteneciente a la parroquia Eloy Alfaro, cantón Latacunga, provincia de Cotopaxi

Abstract

This experimental work is presented as a model for evaluating the road infrastructure of Av. Cotopaxi and Río Cutuchi in the province of Cotopaxi. This research began with a georeferenced study for the representation and location of the road under study. With a traffic study, a manual vehicle count was performed for seven uninterrupted days from 07H00 to 19H00 at 15 min intervals, where it turned out to be the collector type road with a future traffic of 11,473 veh/day. Soil studies were carried out using three pits for the evaluation of optimum moisture content, maximum dry density and, by means of the Proctor test, the liquid and plastic limits were determined. The CBR of each sample was also performed and the Benkelman beam was used to determine the deflections, the behavior of the pavement structure and the subgrade of the road, where type II and IV deflections were found. Through the Pavement Condition Index for flexible and articulated pavements, the road was divided into two sections and the condition of each lane was established. With respect to Cotopaxi Avenue, the left lane has a good quality pavement, unlike the right lane, which is in poor condition, and along Río Cutuchi Avenue, the material used is cobblestone in both lanes, which is in fair condition.
