The FAA's National Airport Pavement Test Facility (NAPTF) was constructed to generate full-scale test data needed for the development of advanced airport pavement design procedures. In this paper, the comparative effects of six-wheel Boeing 777 (B777) and four-wheel Boeing 747 (B747) simulated landing gear loading on the multi-depth deflectometer (MDD) responses of two NAPTF low-strength subgrade flexible test sections are discussed. The results showed that the major contribution to surface rebound MDD displacements was the subgrade layer in both the test sections. Transverse response distributions showed that, in the vicinity of wheel loads, the net average residual MDD displacement was contractive, whereas at small offsets away from the wheel loads, the displacement was dilative which led to a continuous contractive/dilative permanent deformation pattern. The majority of the surface residual response came from the structural layers above the subgrade. |
