ABSTRACT:
The present invention is addressed to the foregoing described need in the art for a mechanized means for filling transverse cracks in roadways. Broadly, the sealant box assembly of the present invention is connectable to a vehicle and adapted to fill transverse roadway cracks wherein the roadway has a center line. Such assembly comprises a sealant box adapted to receive and dispense fluent material onto a roadway; a boom assembly which carries the sealant box and has a drive for moving said sealant box along its length. One end of the boom assembly is positioned for the sealant box to be located at the center line of the roadway while the vehicle is spaced apart therefrom. A chute extends from the vehicle to the sealant box for filling the sealant box with fluent material. Finally, a mounting assembly is connectable to the vehicle and is pivotally connected to the boom assembly for its vertical movement. Advantageously, the mounting assembly is pivotally connected to the boom assembly for both vertical and rotational movement thereof.
