Using the comprehensive Federal Aviation Administration (FAA) PAVEAIR database, this study aims to investigate the consistency and relationship of three indexes: pavement condition index (PCI), structural condition index (SCI), and foreign object damage index (FOD). The statistical analysis results show that the service life of airfield pavement estimated by PCI is significantly longer than the ones estimated by FOD and SCI in general. However, pavement surface type (asphalt or cement concrete) and branch uses (runway, taxiway, or apron) can affect the comparison results between these condition indexes. The study findings indicate that the use of PCI, SCI, and FOD for planning of M&R treatments in airfield pavement management system may not be fully replaced by each other, although correlations were found between them. In addition, it is suggested that different thresholds of pavement condition indexes may be needed by airport authorities for defining the service life runway, taxiway, and apron pavements since their importance levels are different. The study results can be further used in life-cycle cost analysis and selection of M&R alternatives in airfield pavement management system. The ultimate goal is to consider multiple criteria in decision making of airfield pavement management, such as extended pavement life, cost, safety, and sustainability.121
