Heavy-Falling weight Deflectometer (H-FWD)
FWD is a Trailer Mounted Dynamic Impulse Loading Device Used for Structural Evaluation of Pavements.
The unique features of FWD are:
- Follows largely the mechanistic approach
- Enables design/evaluation based on fundamental material Properties
- Loads pavements dynamically and simulates actual traffic loading and loading durations
- Back calculated Layer moduli computed from deflection measurements are nearly representative of the field conditions
