ABSTRACT
This study focused on evaluating airfield flexible pavement responses from surface deflections measured under Heavy Weight Deflectometer (HWD) testing. Finite Element (FE) models were developed to predict pavement responses and develop the synthetic database. Field testing data at the National Airport Pavement Test Facility (NAPTF) were used to validate the FE model results and the proposed deflection-response relationship. The results indicate that good correlations were obtained between tensile strains and Area Under Pavement Profile (AUPP) and between shear strains and Surface Curvature Index (SCI), respectively. Further study will be conducted to enhance the database and improve prediction accuracy.
