A method for making moldable material comprises the initial step of providing a composite material comprised in part of an epoxy. A high performance strand is then distributed in the composite material to form a moldable material. Lastly, the moldable material is heated sufficiently to cause the composite material and the high performance strand to stick at least slightly together without melting the epoxy.

Method for making a charge of moldable material

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

Consumable asphalt containers and method of reducing fumes from a kettle

Asphalt is packaged in consumable containers (10) having breakage means, such as short notches or long channels (110, 111), to allow for easy breakage into smaller portions for ease of handling and feeding into kettles. The containers are advantageously made of an asphalt-polymer composition so that the entire asphalt package may be melted in a kettle, e.g., for use in a roofing or paving application. The containers may have various features to enhance processability and handleability, including a generally rectangular shape and multi-faceted or stepped sides 20 and/or walls 30 with handhold portions and/or scooped portions.
