ABSTRACT:
A consumable container is molded from a composition comprising 40 to 90 weight % of an asphalt and 10 to 60 weight % of a polymer material, which advantageously can include a first polymer such as PP that imparts heat resistance and a second polymer such as EVA that imparts toughness and impact resistance. This molded asphalt/polymer material preferably has an unnotched Izod impact strength of at least 2 joules. The container is consumable--it can be melted along with roofing asphalt held in the container without adversely affecting the properties of the asphalt and without requiring undue mixing. The composition also can be used to reduce fumes normally emitted from a kettle of molten asphalt, e.g., as measured by a reduction of the visual opacity of the fumes by at least 25%, a reduction of the hydrocarbon emissions of the fumes by at least 20%, or a reduction of the total suspended particulates emissions of the fumes by at least 15%. The container may be used, e.g., to hold roofing or paving asphalt or a recyclable petroleum-derived material, such as used motor oil. In one embodiment, the container composition may include one or more ingredients to improve the quality of paving-grade asphalt
