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

An exemplary shingle includes at least one coated shingle sheet defining a headlap portion and a tab portion each having opposed upper and lower surfaces. A first line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a first thermally activated adhesive material. A second line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a second thermally activated adhesive material having a minimum activation temperature less than a minimum activation temperature of the first thermally activated adhesive material.

An emulsified drilling fluid additive includes an emulsion of asphalt, at least one emulsifier, cellulose ether, and water. The asphalt has a softening point of 160 to 212&#xb0; F., a penetration depth of 0 to 45 mm, and a viscosity of 200 to 800 cP at 350&#xb0; F. The drilling fluid additive has an average particle size of 0.1-10 microns. The drilling fluid has an API fluid loss at 7.5 minutes of 0 to 0.5 mL and an API fluid loss at 30 minutes of 0 to 3.5 mL. A method of making the drilling fluid additive includes mixing at least one emulsifier, cellulose ether, and water to form a solution, heating a water-dispersible asphalt to above 300&#xb0; F. and adding the asphalt to the water-based solution in a colloid mill to form an emulsion.
