PLANNING FOR FLEXIBLE PAVEMENT REHABILITATION ON APRON ALPHA USING THE PAVEMENT CONDITION INDEX (PCI) METHOD AT DJALALUDDIN AIRPORT, GORONTALO

Abstract

The condition of flexible pavement in the airport apron area plays an important role in ensuring the safety and
smoothness of flight operations. At the Djalaluddin Gorontalo Airport Operator Unit, there were findings of damage to
the Flexible Pavement Apron Alpha indicating the urgency of the need for proper repair planning. This study aims to
evaluate and plan flexible pavement repairs using the Pavement Condition Index (PCI) method, which has been widely
recognized as a quantitative method for assessing the level of pavement damage. The methodology used includes a
visual survey based on ASTM D5380-98 to identify the type and level of damage, calculating the PCI value for each
sample unit, and comparing the results with the FAA maintenance standards and KP 94 of 2015. The results showed
that the average PCI value of Apron Alpha was in the good to moderate category, with the dominance of damage in the
form of Rutting and Long & Trans Crack. Based on the results of the study using the PCI method, repair planning was
carried out in the form of patching and routine inspections according to the level of damage to each unit. The contribution
of this research is to provide a technical reference based on actual data in airport infrastructure maintenance decision
making, as well as to strengthen the importance of using evaluative methods such as PCI in flexible pavement
maintenance management.
