Abstract: An improved inorganic fiber based roofing shingle for use in both high and low temperature environments is prepared by pre-coating an inorganic fibrous substrate with a polymer/bitumen composition prior to the application of a conventional asphalt or bitumen top coat, wherein the polymer content of the bitumen/polymer pre-coat composition ranges from about 3 to 99% by weight.

Abstract: An all-weather inorganic fiber mat based roofing shingle is prepared using a novel bituminous coating formulation comprising a partially air blown asphalt combined with a styrenic elastomer and mineral stabilizer, which formulation more particularly comprises about 3 to 80% elastomeric polymer composition, 10 to 87% bituminous composition and 10 to 87% mineral stabilizer. In another embodiment, improved low and high temperature pliability and strength properties are also attained by blending recycled rubber or reclaimed rubber into the basic formulation which thereby comprises about 1 to 74% elastomeric polymer composition, 10 to 83% bituminous composition, 15 to 88% mineral stabilizer and about 1 to 74% recycled or reclaimed rubber.

Abstract: A composition and method for reducing the loss of liquids by seepage through permeable ground surfaces is shown. The composition comprises an aqueous emulsion of asphalt including a cationic emulsifier, a nonionic surface active agent and elastomer solids. The compositions are particularly adapted for application to agricultural soils. After application to the ground surface, the surface is flooded with water to force the aqueous emulsion downward into the subsurface. A semi-permeable fluid barrier is created several inches below the surface. The composition and method are useful to create subsurface liquid barriers which permit the surface soil to be used for agricultural purposes.

Abstract: A composition for reducing the loss of liquids by seepage through permeable ground surfaces is shown. The composition desirably comprises an aqueous emulsion of asphalt including a cationic emulsifier, a nonionic surface active agent and elastomer solids. The compositions are adapted for spray, roller, brush or flooding, etc., application, on natural and man-made beds of rivers, ponds and other water impoundment and transfer structures. The stability of the emulsion is controlled so that penetration of the soil is achieved, and a flexible water impervious mass is obtained.
