Falling Weight Deflectometer (FWD)

The Falling Weight Deflectometer (FWD) is a non-destructive testing device which aims to provide information on the bearing capacity of a pavement structure. The FWD drops a known mass from a pre-defined height onto a loading platen.

The load pulse generated is similar to the dynamic load pulse generated by a moving wheel travelling at normal traffic speed. Measurement of vertical deflection provides information on the overall bearing capacity of the pavement.

Software associated with the equipment can be used to analyse deflection data and design a reinforcing overlay to strengthen the pavement if necessary. Testing is carried out by Milestone using the very latest technology Primax 1500 manufactured by Grontmij.
