SPR-4820: Enhanced Methods to Evaluate Flexible Pavement Moisture Damage and Interface Bonding Conditions Using the 3D Ground Penetrating Radar and Falling Weight Deflectometer

The main objective is to develop methodology to evaluate the potential of flexible pavement distresses related to moisture damage and layer interface debonding based on the 3D GPR and FWD deflections. A field investigation will be conducted to establish a framework to identify moisture damage and layer interface debonding using the 3D GPR data. Relationships between FWD deflections and degree of layer interface bonding will be identified using numerical analyses and field investigation. Consequently, a new practical protocol will be developed to evaluate the moisture damage and layer interface bonding conditions of in-service flexible pavements based on 3D GPR and FWD data.
