Abstract
A slipform paving machine includes an offset mold, including a mold frame, a form insert, a form insert actuator and a form insert sensor. A controller receives a signal from an external reference sensor and controls a position of the form insert actuator to control the height of the form insert relative to the mold frame and thereby control a height of at least a portion of a molded structure relative to a ground surface at least in part in response to the signal from the external reference sensor.
