Characterization of Transverse Surface Profiles Acquired at the National Airport Pavement Test Facility

The transverse surface profile data from airport flexible pavement test sections subjected to new generation aircraft loading were characterized using typical distortion indices. A preliminary study was conducted to explore the possibility of determining the relative contributions of the pavement layers to rutting in an airport flexible pavement from an analysis of its Transverse Surface Profile (TSP). The rutting data collected during the first series of National Airport Pavement Test Facility (NAPTF) traffic tests were used. Apart from the rutting data, the NAPTF trench study results which give information about the failed layer in each test section were used to support the current study. The rut depths and the rut areas under six-wheel and four-wheel aircraft test gear loading were similar. The proposed methodology predicted that the predominant contribution to surface rutting was from the subgrade layer in almost all the test sections considered. The study findings indicate the potential for correlating the TSP indices with the origin of rutting in airport flexible pavements.
