• Abstract:
  The National Airport Pavement Test Facility (NAPTF) is located at the Federal Aviation Administration (FAA) William J. Hughes Technical Center, Atlantic City International Airport, New Jersey. It is used to generate full-scale pavement response and performance data for development and verification of airport pavement design criteria. Additional information is available on the FAA Airport Pavement Technology web site (www.airporttech.tc.faa.gov). During the traffic tests, the conventional flexible pavement test item on medium-strength subgrade (MFC) exhibited severe rutting with upheaval outside the traffic lane and asphalt surface (AC) cracking in the wander path. A trench was dug perpendicular to the centerline of the test item at the 367-foot (111.8-m) mark on the test pavement to conduct post-traffic investigation into the failure mechanism of the pavement structure. The trenching involved removal of the P-401 AC layer, the P-209 base, and the P-154 subbase layers to reveal the subgrade interface and subsequent subgrade layers below. Tests conducted on the pavement component layers included CBR, in situ densities and moisture contents, and dynamic cone penetrometer tests. Elevation profiles of the interfaces show clear evidence of shear flow in the subgrade, with vertical movement of the subgrade material in the upheaval areas.
