Fast Falling Weight Deflectometer FFWD EN
Fast Falling Weight Deflectometer (Fast FWD)
The FastFWD is 5 times faster per drop than the FWD and as with the FWD is designed to impart a load pulse to the pavement surface simulating the load produced by a moving vehicle. The load pulse is measured by a load cell with a resolution of 0.1 kPa, and the pavement response is recorded by up to 15 deflection sensors with a resolution of 0.1μm.
