Abstract
The invention relates to a method and an apparatus for measuring the lift of a transport infrastructure road level and industrial floors. The apparatus comprises a wheel borne by a chassis pivotally mounted on a trailer towed by a vehicle. An unbalanced member causes the wheel to vibrate. The vertical acceleration of the chassis and of the wheel and the angle of the centrifugal force of the unbalanced member with the vertical, are continuously measured. The total force applied by the wheel, the chassis and the unbalanced member is calculated from the measurements of the accelerations, as is the deflection of the road level by double integration of the acceleration of the wheel.
