Propuesta de un proceso de conservación para la estructura de la capa de rodadura de la vía Mocha-Pinguilí-Yanahurco, en el tramo de la abscisa k0+000 a k4+000 de la provincia de Tungurahua

Abstract

The section of the road under study at this moment is not in optimal condition, which makes mobility difficult because of the fact that it is the connection point between cantonal capitals such Mocha - Cevallos being a highly productive (populated) area, which causes there to be inefficient marketing of this products. For the development of this technical work, a georeferenced survey was initially carried out with the help of an RTK, this determines the length, width, ditches, water passages, and other sections of the road. A manual count of the types of vehicles that circulate on the road the Annual Average Daily Traffic (TPDA) was determined, this was done during a week with 12 daily hours taken into account from 6:00 a.m. to 6:00 p.m. Subsequently, soil test pits were extracted, two per kilometer, and altered soil samples were obtained to be tested in the laboratory and the granulometry, compaction, Atterberg limits and California Support Index (CBR) test were determined. The Pavement Condition Index (PCI) study was carried out, through which the degree of severity of the damages located in the surface layer was identified. Finally, the test was carried out with the Benkelman beam, which allowed determination of the deflections of the pavement. Once the results of the tests were obtained, graphs, tables, abacuses and plans were made, which allowed them to be clearly interpreted.
