Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate - Baños ABS 8+200 – 11+700 de la provincia de Tungurahua

Abstract

In Tungurahua, being one of the provinces where its inhabitants are engaged to agricultural production, the good condition of the road directly affects communication, development, and well-being of families, which is why timely road maintenance will provide safety and convenience to users. The project generated a maintenance plan for the pavement of the study road where a georeferenced survey, vehicle mobility studies, soil tests and field tests were conducted to determine the state and structural behavior of the wearing course. After carrying out the pertinent tests, it was obtained as a result that the quantified traffic on the study road is classified as a type II collector road that is based on a Regular-Good subgrade according to the average 18 percent of the CBR, it is composed mainly due to poorly graded sands, in terms of the wearing course, it was determined that the study road is in good condition as it reached an average rating of 80.31 points on the Pavement Condition Index (PCI) scale and when evaluated structurally with the Benkelman beam, it presented type I deflections corresponding to an adequate structural behavior. Therefore a routine and periodic road maintenance plan was proposed, according to the current damages evaluated in the wearing course, presenting solutions that allow the rehabilitation, conservation and maintenance of the road so that it meets the design useful life.
