A falling weight deflectometer comprising a load plate adapted to engage a test surface, force transmission means adapted to transmit a force to the load plate, buffer means, and a drop weight. The drop weight is adapted to impact the force transmission means via the buffer means so as to provide a force to be transmitted to the load plate via the force transmission means. The falling weight deflectometer further comprises at least one linear electric motor for lifting the drop weight to a predetermined height above the force transmission means.
