Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Ambato – Tisaleo en el sector Juan Benigno Vela en el tramo de la abscisa 9+600 hasta la abscisa 12+800 de la provincia de Tungurahua

Abstract

In this technical project, a proposal was made for the conservation plan to the structure of the tread layer of the Ambato - Tisaleo road in the Juan Benigno Vela sector on the abscissa 9 + 600 to 12 + 800, which is the responsibility of the study . A georeferenced survey of the study road section was carried out, which was considered an abscissa marking every 20 meters, recording this information with a GPS satellite receiver, allowing to locate and represent the road digitally. The traffic that occurs on the study road during a week was analyzed, exposing it as a collector road, class II, having enough current road width to support the traffic. In addition, a visual inspection was carried out applying the PCI method, reducing to 14 sampling units to study, resulting in a PCI of 83.71, qualifying the road as in very good condition. The static deflections of the tread layer were obtained with the Benkelman beam, in 17 different points of the road, solving that it generates type III deflections, which means that the pavement structure is not well, but it’s subgrade is. Four open-pit wells were drilled to determine the behavior of the subgrade and mainly its CBR value, which was a value of 10 percent that supports the result of the Benkelman beam. Thus, proposing a routine maintenance in which different activities are contemplated for an adequate conservation of the road surface layer.
