ABSTRACT:
A method and apparatus for sealing pavement joints or seams is disclosed. The apparatus includes a wheeled support platform which supports an airtight container of sealant composition which hardens upon contact with the atmosphere. A second airtight container includes a supply of water or other liquid. An air compressor is mounted upon the wheeled support platform and compressed air is selectively coupled to the containers of sealant composition and water. An oil film on the surface of the sealant composition is utilized to prevent it from hardening while in the container. A third output of the air compressor and outputs in the water and sealant composition tanks are coupled to a wheeled applicator which is adapted to be moved over the pavement seam. Compressed air is utilized to blow debris out of the pavement seam and a water mist and bead of sealant composition are pneumatically forced through the applicator from the respective containers in response to the selective application of compressed air to the containers.
