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.

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.

The present invention provides an asphalt paving composition including an essentially water-free, non-foamed warm mix asphalt binder composition modified with lubricating antistrip additives that can be mixed with uncompacted aggregate to provide a warm mix paving composition of the aggregate adequately coated with the essentially water-free, non-foamed binder and lubricating antistrip additive. This warm mix paving composition may be mixed at temperatures of 280 F. or lower and may be compacted at temperatures of 260 F. or lower that are below mixing and compacting temperatures of similar paving compositions that do not contain the disclosed lubricating antistrip additives.

A modified bitumen includes bitumen and a bitumen modifier. The bitumen modifier includes composite particles. The composite particles include aluminosilicate nanostructures defining nanopores and micropores and paraffin wax adhered to surfaces of the aluminosilicate nanostructures. Modifying bitumen includes combining bitumen and the bitumen modifier.

Aging resistant asphalt compositions and related methods of preparing and applying the same are provided. The aging resistant asphalt compositions can include a base asphalt with specified properties combined with an aging resistance additive, to produce modified asphalt compositions having a colloidal index within the range of about 3.7 to about 8.0, a saturates content of less than about 10% by weight, and measurable age-resistant properties. The aging resistant asphalt compositions are useable in a variety of asphalt paving and non-paving applications. The aging resistant asphalt compositions provide improved resistance to both moderate and low failure temperatures of conventional paving asphalts throughout its service life by reducing age-related failures.
