Item Elaboración de un proceso de conservación de la estructura del pavimento de la vía Camino Real (norte) en el tramo km 3+800 hasta km 7+600 del cantón Ambato, provincia de Tungurahua(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-01) Cevallos Pilco, Kevin Israel; Portilla Yandún, Favio PaúlAs an alternative route to the Panamericana Norte that connects the province of Tungurahua and Cotopaxi, the Camino Real (North) route must provide security and serviceability to users. The purpose of this technical project is to study the behavior of the pavement structure and propose a road conservation process for the km 3+800 to km 7+600 section for which a digital model of the road was made with the help of a survey georeferenced using a GPS satellite receiver. The traffic study was carried out from a manual vehicle capacity carried out 12 hours a day for seven days, the average annual and future daily traffic was calculated, classifying the road as a "Collector Road - Class I" according to the MTOP. To catalog the current state of the pavement, the PCI methodology was used, evaluating the pavement condition as "Bad". Moreover, a study of the asphalt folder was carried out, determining the deflections of the pavement by the Benkelman Beam test and the percentage of asphalt present in the asphalt mixture of the track. To complement these studies, laboratory tests were performed on the subgrade material of the pathway, including granulometric analysis, Atterberg limits, modified Proctor Type B, and CBR, concluding that the predominant material in the path is classified as "Silty sand" quality that varies between "Bad" and "Regular - Good". Finally, considering the results of each study, a road conservation plan is proposed
