An adhesive for a roof covering comprises asphalt, polymer and crosslinker. The crosslinker is a phenolic resin or a phenol-aldehyde resin. In another embodiment, the adhesive comprises asphalt, polymer and crosslinker, and it excludes polyfunctional amine having at least two amino groups.

Crosslinked modified shingle adhesive

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.

Method of reducing fumes from a vessel of molten asphalt

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

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.
