US 5,992,628 A · Asphalt packages with consumable containers

Abstract

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.
