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].

1994 to 1996 or for 1998.

scales, or slabs breaking off of surface pavement.
