Abstract:

Disclosed is a mobile sealant material apparatus comprising a frame adapted for vehicular movement and bearing a scraped-surface, indirectly-heated jacketed vessel for housing heated, fluid sealant material. Heated fluid heating media is heated in heating unit and pumped by a pump for recirculating through the jacket of the vessel in heat exchange relationship for heating sealant material housed therein and back to the media heating unit. A sealant material outlet line is attached to the vessel for withdrawing heated sealant material from the vessel. The sealant material in the outlet line also is being indirectly heated by the recirculated heating media from the media heating unit. Finally, sealant material pump is attached to the outlet line for selectively applying heated sealant material, e. g. applying crack sealant to cracks in roadways.

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.
