Abstract: Methods and apparatus for controlling edge slump in newly formed concrete structures formed by a slip form paving machine. An edge height sensor generates an edge height signal corresponding to a height of an edge of the newly formed concrete structure to thereby detect a slumping of the edge of the newly formed concrete structure behind a slip form paver mold. A controller receives the edge height signal, determines whether any slumping of the edge of the newly formed concrete structure exceeds a set slump limit, and automatically controls an actuator assembly at least in part in response to the edge height signal to adjust the height of a lateral edge portion of a mold bottom plate relative to an interior portion of the mold bottom plate and thereby adjust the height of the edge of the newly formed concrete structure.
