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.
