DENSITY LIGHT WEIGHT DEFLECTOMETER (LWD)

Light Weight Deflectometer (LWD) is a light weight, portable tool used to determine the stiffness of unbound materials during construction by measuring the deflection under an applied load. This device is hand operated and takes measurements of the deflection of the compacted soil that is impacted by a falling weight.
