Abstract: An adhesive composition for roofing such as shingles is disclosed which is composed of a hard asphaltic bitumen fraction having a penetration number at 77.degree. F. of from 0 to 30 dmm and a softening point of from about 150.degree. to 220.degree. F. and an elastomeric composition composed of a thermoplastic elastomer and a plasticizer wherein the overall adhesive composition has a penetration number of from 30 to 100 dmm at 130.degree. F. and a softening point of 140.degree. to 230.degree. F. The inventive composition is self-sealing and exhibits excellent squash resistance, low temperature properties and resistance to blowoff. The composition can be used with shingles as well as other types of roofing coverings.

Abstract: A device for the spot application of molten asphaltic composition to spot locations comprising a rod of solid, modified bitumen adapted for heating and end thereof. The softened or molten composition at the end can easily and conveniently be delivered to spot locations.

Abstract: A glass fiber mat having improved strength and fiber wettability is provided by incorporation of a critical amount of between 1% and 6% by weight (solids) of a carboxylated styrene-butadiene latex having a pH between about 5 and about 8.5, a glass transition temperature (Tg) less than 25.degree. C. and a surface tension less than 50 dynes/cm, and 94% and 99% by weight (solids) of a urea-formaldehyde resin solution having a pH of from about 6.5 to about 8.5.

Abstract: A granule application device for use in making a shingle roofing product is provided. This device includes a sheet having a weather protected headlap area and having a weather exposed butt area which moves continuously from an upstream end to a downstream end. The device includes a blender applicator which dispenses blended butt granules on the sticky, asphalt treated, upper surface of the sheet for covering the butt area only. The device also includes a headlap applicator which dispenses less expensive headlap granules on the headlap area only. The device also includes a recycle applicator, which dispenses recycle granules over the blended granules on the butt area only, and dispenses scrap granules over the headlap area only. The moving sheet is supported on a talc drum and a slate drum near the downstream end, and is supported on a back roll near the upstream end thereof.
