Apparatus is disclosed for grading and measuring surfaces such as roadbeds which have curved and inclined profiles which may have different shapes in successive transverse sections of the roadbed. A blade and screw cutter are supported by a frame which extends over the surface being worked, and these tools are movable along this frame. The tools are movable toward and away from the surface being shaped in response to a control means which has memorized the appropriate positions, or by reference to a deformable rule which may also be reshaped in response to computer-memorized data. According to a disclosed method, the rule is reshaped for different sections of the surface. An apparatus for checking and measuring a surface which has a curved profile includes a plurality of piston-cylinder units which are mounted on a main frame. A flexible rule is connected by the piston cylinder units to the main frame, and controls are provided for setting the extended positions of the piston-cylinder units to control the shape of the flexible rule.
