Evaluation of Map Cracking as a Failure Mechanism in Airport Concrete Pavements

Map cracking that can lead to scaling in concrete pavements is a distress that can result in the need to replace airport pavement because of the potential for foreign object debris (FOD) to damage aircraft engines. Recent inspections of airport pavements at several airports using TabletPCs and GIS to map the location and severity of all distresses have shown map cracking to be prevalent. The pavement condition index (PCI), which was originally developed for the US Air Force, rates map cracking as a low severity distress until scaling occurs in five percent or less in a panel of jointed concrete pavement. However, in commercial service airports, having runway and taxiway pavements with any scaling is too great a risk for FOD damage not to repair or replace the pavement. This paper describes a method to rate map cracking in airport pavement, estimate remaining life for map cracking pavements, and justify replacement of map cracked pavements even when the PCI has not reached a number considered critical. This paper also gives case studies of visual inspections of map cracking at Denver, Tampa and Bradley International Airports, and a taxiway replacement decision at Tampa International Airport based upon map cracking.
