Kuab FWD 50

Kuab - bearing capacity measurement

KUAB FWD (Falling Weight Deflectometer)  is a device capable of delivering dynamic loads to the pavement surface, similar in magnitude and duration to that of a single moving, heavy wheel load. The response of the pavement system is measured in terms of vertical deformation, or deflections, over a given area using deflection sensors.
