ABSTRACT:
A method of using repairing cracked or otherwise leaking polymer-modified asphalt-based containers for packaging asphalt. A strip of consumable adhesive tape is adhered to cover and seal the damaged portion of the container. Molten asphalt is then added to the repaired container. The molten asphalt is added to the container at a temperature that is below the melting temperature of the tape. Upon solidification of the asphalt in the repaired container, the entire asphalt package is melted prior to use in a melting apparatus, such as a gas-fired asphalt kettle melter. At the melter temperatures, the tape, container, and packaged asphalt melts or solubilizes in the melted mass.
