Falling Weight Deflectometer

Falling Weight Deflectometer / Heavy Weight Deflectometer (FWD / HWD) is a testing device used to evaluate the physical and mechanical properties of pavement.


The data is primarily used to estimate pavement structural capacity for:


  • Dynamic E-moduli
  • Remaining service life
  • Critical layer(s)
  • Overlay
  • PCN values
  • Load transfer (concrete)
  • Seasonal strength variation
  • Pavement strength influenced by temperature changes


Use includes (but is not limited to) highways, local roads, airports, ports and railways tracks. The FWD / HWD is designed to impart a load pulse to the pavement surface which simulates the load produced by a rolling vehicle wheel.
