Backcalculation of Airfield Pavement Layer Moduli Under HWD Testing
This study focused on evaluating airfield pavement in-situ condition using backcalculated layer moduli from Heavy Weight Deflectometer (HWD) testing. Field testing was conducted using HWD devices at the National Airport Pavement Test Facility (NAPTF) of the Federal Aviation Administration (FAA). Two backcalculation methods based on traditional multi-layer linear elastic (MLE) method and dynamic finite element model (FEM) were used in the analysis, respectively. It was found that the backcalculated moduli were slightly different between MLE and FEM methods. However, significant discrepancies were observed for the backcalculated moduli as compared to the laboratory measured moduli. The study findings indicate that the backcalculated moduli need be adjusted for further use in pavement structural analysis.
