Lightweight Dynamic Plates (LWD)

Lightweight dynamic plates are used to determine bearing capacity and compaction of pavement layers, backfills and subgrade in civil engineering works. A properly calibrated device is key for reliable assessment of compaction quality and thus for the service life and safety of transport and other structures.

Metrological activities for lightweight dynamic plates

  • Calibration of lightweight dynamic plates for pavement and subgrade testing according to STN 73 6192.
  • Calibration on a reinforced-concrete pile with minimal dynamic response, ensuring stable measurement conditions.
  • Verification of the force impulse characteristics when a 10 kg h
