A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

Polymer modified asphalt roofing material

Asphalt-based roofing materials, such as shingles, are disclosed that include a layer of parting material. The layer of parting material is applied to at least a part of the top, bottom, or both the top and the bottom of the shingle. When the shingle includes the parting material on the bottom, the layer of parting material replaces all or a portion of a backdust layer. When the shingle includes the layer of parting material on the top, the layer of parting material replaces a portion of granules on the shingle. The layer of parting material can be applied to the shingle in patterns and configurations that permit an adhesive to be applied to the shingle and function as intended. The parting material may include a metal salt of a fatty acid, a polyolefin, and/or a crosslinkable silane.

Roofing materials including a parting agent layer

Asphalt compositions for use in roofing products are disclosed that include a virgin asphalt material and a reclaimed asphalt material. The asphalt compositions exhibit properties comparable to conventional oxidized asphalt compositions, yet the asphalt compositions are made without using an oxidation or air blowing process.

Asphalt compositions including reclaimed asphalt material

A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The shingle coating asphalt composition comprise a paving grade asphalt that has been overblown to achieve a first penetration value that is at or below about 15 dmm and a first softening point that is at least about 210&#xb0; F. The shingle coating composition may further include an additive that is included in an amount to achieve a second softening point that is less than about 230&#xb0; F. and a second penetration value that is between about 15 and 20 dmm. The additive may comprise at least one ester. The inventive shingle coating asphalt composition may be thermally stable at processing temperatures of at least 450&#xb0; F.

Use of an additive and paving grade asphalt in shingle coating asphalt composition manufacture

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.
