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.
