Heavy-Falling weight Deflectometer (H-FWD)

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
