A method for manufacturing a processed asphalt suspension is provided. The method includes dry grinding shingle waste material to a particle size of less than 1 cm, forming ground recycled shingle material, introducing virgin asphalt into a heated slurry tank and mixing the ground recycled shingle material with the virgin asphalt in the heated slurry tank, forming a mixed asphalt slurry, introducing the mixed asphalt slurry into a wet grinding machine, and recovering a processed asphalt suspension comprising particles having a size no greater than about 200 microns. Roofing and paving products manufactured from the processed asphalt suspension are also provided.

A composition and method for making a heat stable, low application temperature Built Up Roofing Asphalt (BURA) is provided. The composition comprises a wax-modified, air rectified asphalt conforming to Type 3 BURA and, in some embodiments, Type 4 BURA specifications.

Use of a wax-modified, air rectified asphalt in built up roofing asphalt compositions

A method of producing a roofing shingle coating asphalt from a non-coating grade asphalt feedstock includes the following steps. The non-coating grade asphalt feedstock is partially blown to lower its penetration to a first penetration that is within or close to a target penetration range of the coating asphalt, and to raise its softening point to a first softening point that is lower than a target softening point range of the coating asphalt. A wax is added to the partially blown non-coating grade asphalt to further raise its softening point to a second softening point that is within the target softening point range to produce the coating asphalt. The wax may also be added during the blowing process. Resulting roofing coating asphalt compositions may comprise a paving grade asphalt and a wax, and yet still has desirable penetration, softening point and viscosity.

Roofing coating asphalt composition

A roof covering includes a roofing mat formed from fibers of a fiber material. The fibers are coated with a sizing. The roof covering also includes a coating material that coats the mat. The coating material is based on an organic material. The sizing includes a sulfur-containing material that bonds to the fiber material. The sulfur-containing material has sulfur groups that form cross-links with the organic material. In another embodiment, the coating material contains sulfur added to the organic material. The sizing includes a bonding material that bonds to the fiber material and that bonds to the sulfur. The sulfur forms cross-links with the organic material.

A method of producing a roofing shingle coating asphalt from a non-coating grade asphalt feedstock includes the following steps. The non-coating grade asphalt feedstock is partially blown to lower its penetration to a first penetration that is within or close to a target penetration range of the coating asphalt, and to raise its softening point to a first softening point that is lower than a target softening point range of the coating asphalt. Then a wax is added to the partially blown non-coating grade asphalt to further raise its softening point to a second softening point that is within the target softening point range to produce the coating asphalt.

Method of producing roofing shingle coating asphalt from non-coating grade asphalt

In a process of producing a roofing shingle coating asphalt from a low flashpoint asphalt feedstock, an asphalt feedstock which has a low flashpoint of from 490&#xb0; F. (254&#xb0; C.) to 540&#xb0; F. (282&#xb0; C.) is partially blown, and wax is added to the asphalt feedstock. The process produces a coating asphalt having a low melt viscosity of from 50 cps to 150 cps at 400&#xb0; F. (204&#xb0; C.), a softening point of from 190&#xb0; F. (88&#xb0; C.) to 235&#xb0; F. (113&#xb0; C.) and a penetration of at least 15 dmm at 77&#xb0; F. (25&#xb0; C.). In another embodiment, the process produces a roofing shingle coating asphalt having good weatherability from a poor weathering asphalt feedstock. In a further embodiment, the process produces roofing shingles including a filled coating containing a poor tear filler without sacrificing the tear strength of the shingles.

Process of producing roofing shingle coating asphalt allowing more material options

A process of producing a roofing shingle coating asphalt from an asphalt feedstock includes the following steps. Wax and blowing catalyst are added to the asphalt feedstock. Then the asphalt feedstock is blown to produce the coating asphalt. The coating asphalt has a softening point within a range of from about 190&#xb0; F. (88&#xb0; C.) to about 235&#xb0; F. (113&#xb0; C.) and has a penetration of at least about 15 dmm at 77&#xb0; F. (25&#xb0; C.).

A method of repairing a paved surface utilizes a nonwoven or woven fibrous mat made from fibers including polymer fibers, the polymer fibers having a melting point greater than about 320&#xb0; F. (160&#xb0; C.). The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another mat comprises a nonwoven or woven fibrous mat made from fibers selected from the group consisting of mineral fibers, polymer fibers, natural fibers, and mixtures thereof, and a rubbery binder. Another mat comprises a nonwoven or woven fibrous mat made from a blend of high melt polymer fibers having a melting point of at least 350&#xb0; F. (177&#xb0; C.) and low melt polymer fibers having a melting point of less than 350&#xb0; F. (177&#xb0; C.).

Mats for use in paved surfaces

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 improving the weathering of a bituminous coating, a microwave-produced carbon black is added to the coating. The microwave-produced carbon black is added in an amount sufficient to increase the cycles-to-failure of the coating by at least about 10% compared to the same coating without the added microwave-produced carbon black, when tested for weathering according to ASTM D 4799-00.

Use of microwave-produced carbon black to improve weathering of bituminous coating

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.

Asphalt block resistant to cold flow

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.

In a method of reducing voids in an asphalt roofing product, an asphalt coating material having voids is contacted with a vacuum in an amount effective to reduce the voids in the coating material. A mat is coated with the coating material to make an asphalt roofing product. The vacuum contacting step occurs prior to the coating step. The vacuum contacting step causes the roofing product to have reduced voids visible on a top surface compared to the same roofing product made with a coating material not contacted with vacuum.

Vacuum treatment of asphalt coating

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.
