Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate – Píllaro en el tramo de la abscisa 11+400 hasta 15+320 de la provincia de Tungurahua

Abstract

In the present experimental work, a plan for the conservation of the structure of the tread layer of the Patate - Píllaro road is proposed in its 3,920 m of study. A georeferenced survey of the road section under study was carried out, in which an abscissa was considered every 20 m, data were recorded with the GPS satellite receiver, obtaining an amount of 590 points with their respective coordinates, data that allowed the digital model to be made of the track. The vehicular traffic that circulates on the road under study was analyzed, analysis that allowed classifying the road in class II and collector because it receives the traffic of the neighborhood roads. Through the application of the PCI methodology, a section with 17 sampling units was evaluated, whose average value of PCI was 77.82, which corresponds to a very good road classification, which implies maintenance on the road surface. The measurement of the deflections was carried out with the Benkelman beam, for which 20 stations were determined every 200 m along the track, resulting in a type I deflection, which means a good structural behavior of the pavement and the subgrade. 4 openwork calicates were made to perform the tests and determine the type of soil. Edge, gravel and sand type soil has a CBR greater than 30 percent which is used as a subbase, while fine sand and silty soil materials are used as a subgrade.
