Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate - Baños ABS 4+700 – 8+200 de la provincia de Tungurahua

Abstract

Due to the need to provide security and ease of access to users of the Patate-Baños road and in order to promote the economy of these two cantons. A georeferenced survey was carried out using a GPS satellite receiver, obtaining a digital model of the road, a twelve-hour vehicle counting station was carried out for seven days, vehicle mobility was analyzed, Future Traffic was calculated with a projection of 20 years and the road was classified as a class II collector according to (MTOP). To study the current state of the pavement, a visual test was used through the Pavement Condition Method, identifying the type of failure and degree of severity. The PCI average of 78.54 percent was obtained, indicating that the quality of the pavement is "Very Good". The deflections generated were measured using the Benkelman Beam, which allowed classifying the deflections present as Type I. On the other hand, the study of soils in the area was carried out, taking altered samples in situ for laboratory analysis, as a result the soil was classified as silty sand, resulting in an average CBR of 18.66 percent, which belongs to a "Regular - Good" quality subgrade. Considering the results, the use of a periodic type maintenance plan is proposed.
