19 developed ANN models were validated by comparing a new data set collected from both the NCHRP 9-23A project and other literature sources to the model predictions. EQUILIBRIUM SUCTION OF BASE AND SUBGRADE FOR FLEXIBLE AND RIGID PAVEMENTS Researchers developed a correlation model to the predict equilibrium suction in base and subgrade layers based on Thornthwaite moisture index (TMI)

21 PREDICTION OF PAVEMENT PERFORMANCE AND SENSITIVITY ANALYSIS To illustrate the sensitivity of the proposed models as mentioned above, researchers performed a comprehensive sensitivity analysis for both flexible and rigid pavements. For flexible pavements, the proposed SWCC model, MR model, permanent deformation model, and shear strength model are implemented in the FE of pavement structures.
