Diseño de un plan de conservación de la estructura de la capa de rodadura de la vía Picaihua – Chiquicha de la ABS 4+700 hasta 9+400 de la provincia de Tungurahua

Abstract

Due to the importance of the road that connects the Picaihua Parish with Chiquicha, it has been necessary to maintain its good condition of the road surface, being the main road used by many residents for their different daily activities and the economic growth of the place; therefore, the design of a conservation plan for the surface layer structure will be carried out; For this, first a topographical survey was carried out with a GPS RTK, the implementation of the road and its respective plan were obtained using the appropriate software, later a vehicular count point of 12 hours/day for 7 days was established, the vehicular mobility, future traffic was calculated with a 20-year projection and the highway was classified as a class III collector according to the (MTOP). For the current study 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 64.00 percent was obtained, indicating that the quality of the pavement is "GOOD". The general deflections 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 Sand-Silty, resulting in an average CBR of 15.19 percent, which belongs to a "Regular to Good" quality subgrade. Considering the results, the use of a periodic type maintenance plan with a budget of $19497.96 is proposed.
