Diagnóstico multivariable de serviciabilidad mediante fotogrametría desde el kilómetro 16 al 19 de Vía A La Costa, Guayas-Ecuador

Abstract

This research presents a diagnosis of the Present Serviceability Index (PSI) along the E-40 trunk road (Vía a la Costa), specifically between kilometers 16 and 19, a strategic access corridor to the city of Guayaquil. The study analyzes the progressive deterioration of flexible pavement, manifested by fatigue cracking, potholes, and surface deformations that affect user safety and riding comfort. A mixed methodological approach was applied, integrating UAV-based aerial photogrammetry for the identification and quantification of surface distress, together with the measurement of the International Roughness Index (IRI) using the RoadLab Pro application. Based on these variables, the PSI was calculated according to the AASHO Road Test model, incorporating the analysis of Annual Average Daily Traffic (AADT) and population growth. The results reveal a progressive loss of serviceability associated with increased traffic demand and the interaction of multiple functional variables influencing pavement performance.
