Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate - Píllaro en el tramo Km 15+320 al Km 19+150 de la provincia de Tungurahua.

Abstract

The road conservation process is applied on the Patate -Píllaro road, section 5 that corresponds from km 15 + 320 to km 19 + 150 of the Píllaro canton of Tungurahua province. From the traffic study, the current TPDA of the road is 2666 vehicle / day, classifying an Order II type Collector road that collects all the traffic from the neighborhood roads, as well as the parishes of San Miguelito Emilio Terán. For the visual evaluation of the surface, the PCI Flexible Flooring methodology is applied, which is a simple, economical and easy to apply method, it evaluates the superficial state of the road by means of the Pavement Condition Index that shows the damage class, level of severity and density. The beam Benkelman evaluates the structural behavior of the road, this test is the type of non-destructive and easy to apply, with this method, the behavior of the subgrade is good, but the behavior of the pavement structure is bad, you must have that the road studied does not have an adequate pavement structure, as far as this method is concerned, pits have been made to respect the study of soils. In the study of the floors it is verified that the properties that have the base of the structure of the pavement, do not fulfill the specifications of the MTOP, but the characteristics of the subgrade are good to settle a structure of the pavement. Carried out the process that proposes this model of road conservation, the reconstruction of the Patate - Píllaro road is made, section 5 that corresponds to km 15 + 320 to km 19 + 150.
