Evaluación de patologías método Vizir en pavimentos flexibles y posibles técnicas de rehabilitación del tramo comprendido entre el KM 8+500 hasta el KM 9+000 de la vía Ibagué-Rovira, departamento del Tolima

Resumen

n the present grade work an evaluation and characterization of the different pathologies of the flexible pavement associated to the section between Km 8 + 500 to km 9 + 000 via Ibagué-Rovira is carried out through the VIZIR methodology adapted from the Invias INV Standard E-813-13. In addition to providing possible rehabilitation techniques that the study section may have; taking into account the state of surface drainage works. The above to improve the entire road infrastructure of the country which is constantly growing and innovating with the new 4G road models. A series of field activities were carried out which include Georeferencing with Garmin-type global satellite positioning (GPS) devices to determine the geographic coordinates of the affected stretch. A visual study and inventory of the structural and functional pathologies found in both lanes of the track was carried out. The surface condition of the pavement was determined, through the Index of surface deterioration (IS), which indicates the total condition of the pavement and thus take the strategy for the possible rehabilitation of the road. A traffic study was carried out through vehicle capacity to determine the capacity and level of service; and the severity or severity was determined according to the Frances VIZIR method, to model the pathway with the help of Arcgis software.
