Evaluación del estado de la capa de rodadura de la red vial intercantonal de los cantones: Ambato, Tisaleo, Cevallos, Quero y Mocha de la provincia de Tungurahua

Abstract

Due to the need to provide free mobility and decrease travel times in the sections studied and in order to help the institutions in charge of these activities to carry it out in a timely and economical manner, it is necessary to carry out a road evaluation and establish a maintenance plan, prolonging the useful life of the tracks. For the present technical project, a georeferenced survey was carried out, it was processed using cartographic software, obtaining maps of location, implementation and identification of failures of each road. The analysis of the current state of the pavement was carried out by collecting information generated with the Pavement Condition Method (PCI), identifying the type of failure that each road has together with its respective severity, determining the averages of the PCI for the four pathways, and noting that the predominant faults are crocodile skin and longitudinal and transverse cracks; therefore, the condition of the pavement was described in a qualitative way, distinguishing that the Ambato-Tisaleo, Manzana de Oro-Quero roads together with a large part of the Cevallos-Mocha road need "Periodic Maintenance", a section of Manzana de Oro -I want in the ABS. 0+000-2+400 km needs Rehabilitation” and the Montalvo-Totoras road requires Routine Maintenance. Finally, with the information collected, a technical proposal for adequate and precise road maintenance was made for each type of failure.
