Abstract
A slip-form paver is provided which is capable of paving a lane of concrete or other material in much the same manner that asphalt is spread as a top paving surface for a roadway. Spreading and levelling means are not restricted to the space between the traction members of the tractor portion of the machine, but are arranged behind such members so that the slab may be wider than, or offset, with respect to the distance between such traction members. The mounting of the final paving tool is capable of lateral movement independently of the steering of the tractor members so as to enable it to turn on a different radius. The elevation of this tool may also be controlled from a string line or the like so as to provide the desired pavement surface contour.
