Diagnóstico del pavimento usando el método PCI en la vial 2, Daule – Ecuador

Abstract

This study focused on evaluating the flexible pavement of Highway 2 in the Daule canton, with the objective of applying the Pavement Condition Index (PCI) and generating a technical diagnosis to serve as a basis for planning maintenance, conservation, and rehabilitation actions. The methodology involved systematic visual inspection, identification and recording of deterioration, classification of defects according to type and severity, and calculation of the PCI per unit of analysis according to ASTM D6433. This included processing densities and corrected deduction values to obtain the final indicator. The results show a generally fair condition, with an average PCI of 46.7, and variable performance along the section: 2 excellent sections, 3 very good sections, 4 good sections, 7 fair sections, 4 poor sections, 5 very poor sections, and 2 failed sections were identified. The section with the greatest deterioration was section 41, with a PCI of 4, while the best condition was observed in section 35, with a PCI of 94. The predominant failure was alligator cracking, with a medium severity, reflecting significant fatigue processes in specific areas. Based on these findings, guidelines are proposed for priority corrective interventions in critical areas and preventive maintenance in sections with incipient deterioration, highlighting the usefulness of the PCI method as a technical tool for decision-making, prioritizing needs, and optimizing resources in road management.
