Abstract
Reconstituting the profile of a pavement consists of moving three contactless distance-measuring sensors over a pavement, the sensors being equidistant and in horizontal alignment in the direction of motion. The sensors deliver signals representative of their respective heights above the pavement. Measuring the distance traveled by the sensors, and measuring twice the height measured by the middle sensor from the sum of the heights of the two end sensors. The apparatus has a horizontal beam fitted with three sensors, a device for measuring the distance traveled, and a computer, the assembly being mounted on a load-carrying chassis or vehicle.
