Abstract: Asphalt is packaged in containers having breakage means, such as short notches, long channels, wedges or molded parts, to allow for easy breakage into smaller portions for ease of handling and feeding into kettles. Asphalt is also packaged so as to improve cold flow of the block while simultaneously reducing fumes at the kettle. The containers have various features to enhance processability and handleability, including a handhold portions and/or scooped portions.

Abstract: A method for substantially reducing sulfur-oxide emissions from an asphalt air-blowing process involves adding an emission-reducing additive to the asphalt prior to air-blowing, or early in the air-blowing process, and filtering the flue gases produced in the process. The emission-reducing additive includes at least one metal hydroxide, metal oxide, metal carbonate, or metal bicarbonate, where the metal is sodium, potassium, calcium, magnesium, zinc, copper, or aluminum. The filter is preferably of the fiber-bed type, and removes at least a portion of the sulfur-containing compounds via condensation. The filtered stream of flue gases is subjected to an incineration process before being passed into the atmosphere.

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.

Abstract: A method and apparatus for packaging a low-fuming meltable asphalt composition which includes the introduction of pellets comprising one or more polymeric materials into molten asphalt flowed into a conventional container or carton.

Abstract: A penetration pocket, useful to seal roof openings at protruding pipes or the like, is made of a material compatible with roofing asphalt. The penetration pocket material is asphalt-based with polymeric materials added to impart strength and toughness. Fibrous material may also be added for increased strength. The roofing asphalt, when applied around the penetration pocket, fuses with penetration pocket walls and base, and upon cooling, the penetration pocket and the roofing asphalt are welded together to effect a secure, water-proof joint.

Abstract: The present invention provides an elastomeric-asphalt composition which does not phase separate and which is compatible at high temperatures. This compatible material can be produced without the need to use high shear milling equipment. The elastomeric-asphalt composition is not limited by the tendency of other elastomer polymers to be incompatible with asphalt nor does the composition separate into a polymer-rich phase and an asphalt-rich phase. In a preferred embodiment, the elastomeric materials are SBS and SIS block copolymers.

Abstract: In making entangled fibrous products by depositing fibers from streams of hot gas in which they are entrained, dust suppressant incorporated in the product by introducing at least a portion of it into the cooler region surrounding and separating the fiber-entraining streams of hot gas and communicating with the zone wherein the fibers are deposited minimizes smoke evolution as compared to introducing such portion into the hot gas streams.
