Abstract: A coating material for coating a pipe contains asphalt and polymer dissolved in organic solvent. The coating material has Theological properties such that it can be easily applied at ambient temperature to form a coating on the pipe. After drying, the coating is resistant to abrasion as measured by at least about 1,000,000 revolutions before failure when tested by ASTM A 926-97, Procedure 7.4.

Abstract: In a method of melting asphalt in a vessel, the molten asphalt normally emitting fumes, 0.2 weight percent to 6 weight percent of a polymer is added to the asphalt to reduce the visual opacity of the fumes by at least 25% over the same asphalt without the polymer. In another embodiment, the total emissions of benzene soluble suspended particulates is reduced by at least 15% over the same asphalt without the polymer. Preferably, the added polymer has a melt flow index of from 15 grams/10 minutes to 95 grams/10 minutes, and the added polymer reduces the visual opacity of the fumes by forming a skim on the upper surface of the molten asphalt.

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: A method for providing a roof structure having a plurality of trusses spaced apart from one another in a parallel arrangement is disclosed. The trusses each have a top portion. A support sheet is payed out so that the support sheet depends from the top portions of adjacent trusses. Flexible insulation material is applied above the support sheet so that the flexible insulation material is supported by the support sheet. Metal deck sheets are fastened to the top portion of the trusses, thereby forming a metal deck. A temporary waterproofing sealant is applied to the metal deck to protect the flexible insulation material, thereby creating a partially completed roof structure. Rigid insulation board and a waterproofing membrane are subsequently applied onto the metal deck, thereby forming a completed permanently sealed roof structure.

Abstract: An ink contains a petroleum-derived asphalt, a colorant, and a carrier for the asphalt and colorant. The asphalt has a softening point from 105.degree. C. to 155.degree. C. and a saturates content not greater than 32% by weight. Preferably at least 50% by weight of the carrier is a material selected from aliphatic oils, aliphatic solvents, and mixtures thereof. A method of making the ink includes granulating the asphalt to a particle size not greater than 2.38 mm (8 mesh), dissolving the asphalt in the carrier, and adding a colorant to the carrier.

Abstract: A method of coating a corrugated pipe includes preparing an asphalt composition having a polymer constituent within the range of from about 3 to about 20 percent by weight, the composition having a softening point within the range of from about 180.degree. F. to about 250.degree. F. and a viscosity at a temperature of 360.degree. F. within the range of from about 600 to about 4000 cps, heating the asphalt composition to a temperature within the range of from about 340.degree. F. to about 390.degree. F. and coating the corrugated pipe by positioning at least a portion of the corrugated pipe in the heated asphalt composition for a time sufficient for the corrugated pipe to reach a temperature of at least 150.degree. F. The coated pipe is then removed from the asphalt composition for cooling.

Abstract: Bis-stearoylamide is blended into asphalt, either natural or petroleum derived, to reduce the viscosity of the asphalt while maintaining its viscosity and, hence, its saturant properties.
