Abstract: The invention teaches a slip form paving machine which can be used for both zero clearance variable width and variable width conventional paving using the same paving pan. The main frame of the machine is designed to hydraulically extend and retract from varying desired widths. The paving assembly, attached to the main tractor assembly frame, is adjustable as wide as the width of the main frame of the machine or further past the exterior limits for additional clearance, if required. The paving pan, which is part of the pan assembly, can also be extended to conform to these various widths. In a “zero clearance” paving mode, the same pan is located behind the main tractor frame, whereas in conventional paving, the pan is located under the center of the main frame inside of the tracks. In addition, the paving pan can be adjusted to pave varying surface angles, if required.
