Elaboración de un proceso de conservación de la estructura del pavimento de la Vía Camino Real (norte) en el tramo km 7+600 hasta km 11+400 del cantón Ambato, provincia de Tungurahua

Abstract

The Camino Real (North) road, which is considered an alternative to the Panamericana Norte, allows moving from the canton Ambato to the canton Salcedo in Cotopaxi, helping the mobility and economic growth of the sector; Consequently, there has been evidence of an increase in heavy traffic causing the rolling layer of the latter to deteriorate. At the beginning of the investigation, the georeferenced survey was carried out for the location of the road, followed by a manual vehicle capacity for the determination of the TPDA and future traffic, classifying it as a "Collector - Class I" road. Also, a visual inspection and evaluation of the current condition of the pavement were carried out using the PCI method, identifying recurrent faults such as alligator cracking, potholes, patches, and weathering, obtaining an average PCI value of 68.15 corresponding to a "Good" state. Similarly, the deflection measurement test was performed with the Benkelman beam, resulting in a "Type I" deflection. Finally, to complement the work, laboratory and field tests were carried out on soil samples representative of the area such as granulometric analysis, Atterberg limits, modified Proctor, CBR, field density, and natural moisture, which is mostly classified as a "silty sand" type soil. Based on the results obtained, repair options were proposed according to the type of fault.
