Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Patate - Baños ABS 18+700 – 22+200 de la provincia de Tungurahua

Abstract

The quality of the road infrastructure of a town is a fundamental pillar for the integration of several sectors, the large agricultural production of Patate and the tourism generated by the Canton of Baños have been the factors that directly influence the need to have a road network in the best operating conditions, providing comfort and safety to all users. For the present project, a Georeferenced survey of the road was carried out with the help of a tape measure and a GPS, a total of 376 points were collected, data reflected in a digital model. A manual count was carried out in the area with the highest vehicular mobility for 12 hours from Monday to Sunday, obtaining a future traffic of 20670 veh/day, a value that classifies the road as a highway or multilane road AV1. The pavement condition index (PCI) was determined, which resulted in 71.20, a value that qualifies the pavement as Very Good. The deflections of the pavement were determined every 200 meters, finding that the road presents type I deflections with a behavior of the subgrade and the pavement of good quality. 3 soil samples were collected to perform granulometry tests, Atterberg limits, Modified Proctor and CBR, classifying the soil as a silty sand (SM) of RegularGood quality and exclusive use for subgrade. Through the results obtained in the different investigations, a Routine Maintenance was planned, which will be carried out at least once a year and its objective will be to preserve the Patate-Baños road in optimal conditions.
