This research aims to assess the FAA's pavement design methods using long-term condition data from U.S. airports.
Evaluated pavement design methodology using empirical data from 179 airports.
Calculated PCI and SCI values using FAA PAVEAIR software for over 10,000 pavement sections.
Analyzed performance trends by surface type and validated theoretical deterioration models.
Bilinear SCI model for rigid pavements matched observed data with an inflection point around 24 years.
Flexible pavements exhibited faster deterioration with environment-related distresses being prominent.
Average rehabilitation age was 15–18 years for flexible and 32 years for rigid pavements, with PCI values between 61 and 67.
