Resumen
Mediante una inspección descriptiva, se evaluó la capa de rodadura del pavimento existente para detectar las actuales fallas en la vía. Este análisis visual se sustentó en el método del PCI, esencial para determinar el estado general del pavimento a lo largo de su trayectoria. Además, se ejecutaron pruebas de laboratorio para examinar las propiedades físico-mecánicas del suelo, en la estructura del pavimento y la subrasante. Los resultados revelaron la necesidad de reemplazar la estructura en el tramo entre las abscisas 0+000 hasta la 1+228.5 debido a un PCI inferior al 40%, categorizando el pavimento como deficiente. Se efectuó un estudio de tráfico para proyectar el número de ESALs a 20 años, lo que posibilitó el diseño de una nueva estructura mediante el método AASTHO-93. En las secciones restantes, el PCI indicó un estado favorable (superior al 55%), respaldado por pruebas de laboratorio que confirmaron las óptimas condiciones del suelo.
By means of a descriptive inspection, the existing pavement wearing course was evaluated to detect current road failures. This visual analysis was based on the PCI method, which is essential to determine the general condition of the pavement along its path. In addition, laboratory tests were performed to examine the physical-mechanical properties of the soil, pavement structure and subgrade. The results revealed the need to replace the structure in the section between abscissae 0+000 to 1+228.5 due to a PCI of less than 40%, categorizing the pavement as deficient. A traffic study was carried out to project the number of ESALs for 20 years, which made it possible to design a new structure using the AASTHO-93 method. In the remaining sections, the PCI indicated a favorable condition (greater than 55%), supported by laboratory tests that confirmed optimal soil conditions.
