Road maintenance model, with flexible pavement in the central zone of Ecuador

Abstract

Introduction: This work is a general study of road maintenance with a flexible pavement structure to keep this type of roads in an efficient state, for which the following samples have been taken as reference, Montalvo-Totoras, Quero-Salasaca, Golden Apple-Quero roads, Patate-Píllaro, Patate-Baños, Pelileo-Patate, Cevallos-Mocha and Ambato-Tisaleo, which are patterns selected to guide the country's road maintenance, said sample are roads belonging to the inter-cantonal network of the central zone of the country, same that meets the best conditions for an analysis of flexible pavements. Objective:  General study of road maintenance with flexible pavement structure to keep the roads of the middle area of Ecuador in efficient condition. Methodology. In this work, compilation information processing was conducted on the current state of the flexible pavement visually through the Pavement Condition Index (PCI) Method, in which the type of failures and their severity were identified, deflections generated in the Beam. of Benkelman, which served as a basis for developing a general maintenance plan to be used. Results. Details were obtained by sampling units, PCI results and deflections per Benkelman beam for each of the locations, tracks, and apses to be studied in this report. Conclusions. A general proposal for road maintenance of the studied roads has been presented, where it was found that the inter-cantonal network needs periodic maintenance for the most part and rehabilitation in the most deteriorated areas. And routine maintenance on roads whose deterioration is slight.
