Elaboración de un proceso de conservación de la estructura del pavimento de la vía Camino Real (norte) en el tramo km 0+000 hasta km 3+800 del cantón Ambato, provincia de Tungurahua

Abstract

In order to extend the useful life of the Camino Real (North) road from km 0+000 to km 3+800, a pavement conservation process was carried out, carrying out different activities to find out its condition and thus determine a conservation plan according to your needs. A topographical survey of the section was carried out, which provided detailed information on its dimensions. From this survey, a digital model of the road was obtained. A vehicle counting station was located for traffic analysis, the vehicular flow was projected for a design period of 20 years, resulting in the road being classified as a Class I Collector according to the MTOP. To assess the condition of the surface of the pavement, a visual inspection was carried out following the PCI methodology, from which it was obtained that the condition of the pavement is "Regular". In the same way, soil studies were carried out to know the properties of the subgrade and, in this way, it was classified as Silty Sand. From the CBR test it was established that the subgrade has an "Excellent" quality. The elastic deflections of the pavement were measured with the help of the Benkelman Beam, obtaining that the deflections presented are of Type III. Finally, a conservation plan is presented, in which the results obtained from the various tests are considered.
