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: An improved inorganic fiber mat containing mineral wool, preferably a composite mat of mineral wool and fiberglass, is prepared by:(a) forming an aqueous slurry of the inorganic fiber raw material containing non-fibrous, particulate contaminants;(b) agitating the slurry to separate heavier contaminant materials;(c) passing the slurry through a unique cleaning apparatus whereby the moving slurry is cascaded and subjected to air induced hydraulic turbulence to separate any remaining contaminant materials; and(d) thereafter transferring the fibrous material, preferably as an admixture of cleaned mineral wool fibers and glass fibers, to a mat forming device.

Abstract: The present invention relates to a hydraulic cement composition having a boron- and halogen-containing component and unusually high full term as well as early strengths and acceptable setting time characteristics, which cement is characterized by the presence, as hydraulically settable calcium silicates, of about 20-70 percent of alpha-prime dicalcium silicate (.alpha.'--C.sub.2 S) and about 10-50 percent of tricalcium silicate C.sub.3 S based upon the weight of the composition.

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.

Abstract: Ground mixtures of conventional Portland cementmaking components are mixed with relatively small amounts of boron-containing components, and the mixtures are burned at kiln temperatures substantially below those normally utilized to form clinker. The .[.resultant clinker is more easily grindable than that produced in conventional processes of Portland cement production, and the.]. cement resulting from the grinding of the clinker yields cementitious products possessing substantially higher compressive strength than is exhibited by Portland cement made from the same components in the absence of the boron-containing component.
