Dynatest developed the first commercially available Heavy Weight Deflectometer. The HWD can apply a loading in the range of 30-320kN, enabling it to simulate even the most extreme aircraft wheel load such as the Boeing 777, the Airbus 340 or 380. The HWD is highly versatile and can be used to test on both rigid, paver block and flexible pavements used on roads and airports. The HWD meets all HWD standards worldwide.
