Abstract
An apparatus for regulating a flow of pavement rejuvenation materials for deposit on a roadway is disclosed in one aspect of the invention as including a first channel is supported by a pavement recycling machine and is in communication with a supply of pavement rejuvenation materials; a second channel slideably coupled to the first channel, the pavement rejuvenation materials adapted to flow through the first and second channels; and a hardened tip coupled to the second channel. The apparatus may also have a seat coupled to one of the channels; and a blocking element coupled to the other of the channels. Upon sliding the first channel with respect to the second channel, the blocking element contacts the seat, thereby impeding the flow of pavement rejuvenation materials flowing through the channels.
