Airport Runway Conditions

Airport Runway Conditions

Airport runway conditions stayed about the same at the nation's major public-use airports (box 2-B) between 1997 and 20041 [1, 2]. At the nation's commercial service airports, pavement in poor condition remained at 2 percent from 1997 through 2004 (figure 2-8). At the larger group of National Plan of Integrated Airport Systems (NPIAS) airports, the Federal Aviation Administration (FAA) found poor conditions on 4 percent of runways in 2004, down from 5 percent in 1997 (figure 2-9).

FAA inspects runways at public-use airports and classifies runway condition as good, fair, or poor. A runway is classified as good if all cracks and joints are sealed. Fair condition means there is mild surface cracking, unsealed joints, and slab edge spalling.2 Runways are in poor condition if there are large open cracks, surface and edge spalling, and/or vegetation growing through cracks and joints [2].
