Apparatus for sealing pavement seams
First Claim
1. An apparatus for filling the gap between pavement sections with an asphaltic emulsion sealing composition comprising:
- a wheeled support platform;
a storage container disposed on said wheeled support platform for containing an asphaltic emulsion sealing composition;
applicator means coupled to a bottom portion of said storage container for coupling a stream of said asphaltic emulsion sealing composition into said gap between pavement sections; and
means for preventing gelling of said asphaltic emulsion sealing composition in response to movement of said wheeled support platform, said means for preventing gelling comprising a substantially vertically disposed rotatable shaft in said container driveably connected to said wheeled support platform;
said shaft having a first agitator disposed within the bottom portion of said container for propelling asphaltic emulsion upward from the bottom of said container, and a second stirring means disposed above said first agitator for stirring said asphaltic emulsion.

Abstract
Apparatus for sealing pavement joints or seams are disclosed. The apparatus includes a wheeled support platform which serves to mount a cylindrical storage container suitable for holding a selected amount of an asphaltic emulsion sealing composition. An applicator is coupled to the bottom of the storage container and controls are provided to selectively vary the volume of the stream of sealing composition and to permit the stream to be completely extinguished. In order to prevent the asphaltic emulsion sealing composition from breaking down or settling out during application an agitator device is provided which propels the sealing composition upward from the bottom of the storage container and mixes the sealing composition. In a preferred embodiment of the present invention the agitator device is gear driven in response to movement of the wheeled support platform.
