What does LWD mean?

Light-Weight Deflectometer (LWD) is a lightweight portable tool used for measuring the bearing capacity (deflection) of unbound materials such as subgrade/subsoils, base layers, granular layers, and backfilling materials. It is used to measure in-place soil parameters such as stiffness and strength.

LWD is a hand-operated tool and takes measurements of the deflection of the compacted soil that is impacted by a falling weight. The device consists of a circular plate that is placed on the foundation layer, and a weight that is dropped onto this plate via a damping mechanism. Measurements of the load applied and the resulting deflection can be used to calculate the layer stiffness.
