Abstract: An indirect heating, drying and mixing chamber has a drum. A mixing/conveyor mechanism is positioned within the drum mixing and moving materials through the drum. An enclosure is provided wherein the drum is inserted within the enclosure to form an upper section of the enclosure between the drum and a top surface of the enclosure and a lower section of the enclosure between the drum and a bottom surface of the enclosure. A plurality of heat openings is formed on the bottom surface of the enclosure. A plurality of heating elements is provided, wherein an individual heating element is coupled to a corresponding heat opening, the plurality of heating elements generating heat which travels along the lower section of the enclosure and through the upper section of the enclosure heating the material in the drum.

Abstract: A composition for pelletized bitumen and a method for preparing the same is disclosed. The composition is comprised of: between approximately 30% to approximately 40% by weight of bitumen; between approximately 15% to approximately 30% by weight of stiffening compound; between approximately 35% to approximately 45% by weight of setting compound; and approximately 0.05% by weight of water. The stiffening compound is comprised of between approximately 10% to approximately 20% by weight of ground asphalt shingles; between approximately 5% to approximately 10% by weight of vulcanized rubber; between approximately 1% to approximately 2% by weight of uintahite; and up to approximately 0.5% by weight of zeolite. And the stiffening compound may be Type II Portland cement.
