Abstract: An improved method and apparatus of inserting dowel bars into a newly formed concrete road surface at locations for at least partially forming transverse joints therein includes a slip forming machine for laying a strip of newly formed concrete. A dowel bar placement pan subframe is operably connected to the frame of the machine and extends generally transversely to the direction of forward movement of the frame. The subframe has a plurality of parallel slots disposed therein along the length thereof. A trolley is provided for traveling back and forth across the subframe and has a mechanism therein for storing a plurality of dowel bars therein and permitting the stored dowel bars to roll downwardly one behind the other. A dowel bar stopping device is provided for stopping the lowermost one of the dowel bars at a predetermined position with respect to the trolley.
