Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Ambato – Quisapincha en el tramo de la abscisa 0+000 hasta la abscisa 3+200 de la provincia de Tungurahua

Abstract

Firstly, in order to elaborate this technical project, it was necessary the preparation of a digital model of the road. It was carried out with the help of a georeferenced survey of the road section studied, in which the information was registered with a GPS satellite receiver, taking into account every 20 meters marking of abscissas. Moreover, the vehicular traffic on the road was recorded for one week, which resulted in a class III collector road with a roadway width that supports the current traffic. Additionally, a visual study of the road was performed by applying the PCI method, taking into account 16 sampling units to be analyzed. It gave a PCI value of 66.50 showing that the road is in good condition. Furthermore, an analysis of the static deflections of the wearing course was obtained with the help of the Benkelman beam, which generated type I deflections, indicating that the road has a good structural behavior. Finally, four trial pits were made to get the CBR value, which got a 8 percent value, giving an average to a good subgrade performance. For these reasons, routine maintenance is proposed in which includes different activities to keep wearing course in excellent conditions.
