Abstract: A method for reinforcing pavement involves the orientation of a sheet of elastomeric material reinforced by a plurality of substantially parallel, high tensile strength tire cords embedded therein and bonded thereto on a roadbed so that the tire cord fibers extend in the direction of the stress on the roadbed. The elastomeric material and the tire cord fibers are bonded to the existing roadbed and the roadbed is paved.

Abstract: Sized glass fibers are rendered less tacky by treating glass fibers with a sizing composition having a blend of components. The sizing composition has about 0.5 to about 2 weight percent of liquid hydroxylated styrene butadiene copolymer, about 0.35 to about 2 weight percent of one or more emulsifiers, about 0.5 to about 1.5 weight percent of a wet lubricant, about 0.5 to about 3 weight percent of one or more dry lubricant oils or waxes and about 0.3 to about 2 weight percent of an organo silane coupling agent. All of the weight percents are of the total aqueous sizing composition. The emulsifier or emulsifiers are those having a fatty acid portion with carbon to carbon chain lengths of at least 14 to about 20 carbon atoms. The wet lubricant has a nitrogenous group to provide hydrogen bonding with the surface of the glass fibers.

Abstract: An elastomeric coating composition for glass fibers is provided that gives the glass fibers improved weaveability. The coating contains an elastomeric latex, an external plasticizer that is soluble, dispersible or emulsifiable in the elastomeric latex; an antioxidant; and an elastomeric curing agent. Also the coating composition can contain melamine aldehyde polymer, emulsifier, wetting agents, surfactants, synthetic waxes, stabilizers, lubricants, solubilizing agents and anti-foaming agents.

Abstract: Adhesive - sealant compositions useful for bonding metal and/or glass surfaces are disclosed. These adhesive - sealant compositions are comprised of an aluminous cement and the reaction product of a tetracarboxylic dianhydride or a tricarboxylic monoanhydride and a dihydrazine, dihydrazide or aromatic diamine. The adhesive sealant is capable of withstanding surface temperatures of up to 1,000.degree. F. without loss of adhesive or sealing properties.

Abstract: Glass fiber filament bundles such as cords for rubber reinforcement are impregnated and coated with an elastomer composition such that the coated cord maintains adhesion and tensile strength even in a moist environment due to the inclusion in the coating of a chemically treated diatomaceous earth. These chemically treated diatomaceous earths contain a major portion of an alkali earth metal silicate.

Abstract: Individual glass fibers are coated with a combined sizing and coating composition that includes a zinc salt having a solubility constant (K.sub.s) of not less than 1 .times. 10.sup.-.sup.3 complexed with ammonia as a substitute for all or part of the resorcinol-formaldehyde resin. The preferred combined sizing and coating composition includes as the latex constituent, a styrene-butadiene vinylpyridine terpolymer, as the resin constituent, resorcinol-formaldehyde and zinc sulphate complexed with ammonia and as the coupling agent, a silane selected from amino, amido, chloropropyl, epoxy, ureido-functional silanes. An aqueous solution of the combined sizing and coating composition is prepared and the individual glass fibers are coated shortly after attenuation with this combined sizing and coating composition. The coated individual glass fibers are thereafter gathered into strands and the strands are dried while spaced from each other. The dried strands are thereafter, collected on a forming tube.
