Abstract
A system is provided for varying the width of a molded concrete slab on the fly as the slab is being molded. Position and height of the paving machine relative to an external reference system are determined and controlled using at least two 3D stringless reference objects. An additional sensor provides a signal corresponding to a frame width and thus a concrete slab width, and an actuator controls the frame width actively as the paving machine advances.
