Diseño de un plan de conservación de la estructura de la capa de rodadura de la vía a Pelileo - Chiquicha, ABS 4+000 - 8+000, provincia de Tungurahua

Abstract

A study of the current state of the Vía Pelileo-Chiquicha was carried out due to the high commercial and tourist mobility it has, which is why its surface layer has considerable deterioration. Due to this situation, it was necessary to analyze the failures and conditions of the road, recognizing the areas with the most wear and critical failures, thus proposing a conservation plan that allows safe and comfortable circulation. It began with the execution of a research process to develop a georeferenced topographic survey, obtaining 550 points. The vehicle count continued for 12 uninterrupted hours for 7 consecutive days, determining the projected TPDA and TPDAf for 20 years, considering the road as a Class II Collector. Subsequently, the study of the soil was carried out by means of granulometry tests, Atterberg limits, for which test pits of one cubic meter were made for each kilometer and the California Support test, obtaining an average of 12.24 percent that belongs to a Regular to Good subgrade, in addition, an analysis of deflections in the road surface was carried out using the Benkelman Beam, yielding type I deflections and the Pavement Condition Index method, identifying that the road is located in good condition since his average is 56.63 points, needing a rehabilitation. Once these analyzes have been identified, a periodic road maintenance plan is required to obtain a referential budget of de $ 70.564,50 for its conservation.
