A membrane for waterproofing a building component, e.g., a roof or a basement wall. The membrane includes a first layer of asphalt-elastomer blend which preferably is self-adherent to the building component and an overlying layer of plastic film which bears at least one adhesive strip adhered to the plastic film. The membrane is in the form of elongated strips which are overlapped to cover the building component, and the adhesive of each strip ensures a waterproof joint between the laminae of the overlapped strips.

Waterproof membrane

An asphaltic coating composition in the form of an emulsion of chemically modified asphalt and a normal, non-modified asphalt in an aqueous emulsification medium. The emulsion can be used as a primer or damp-proof coating and has good adherence to concrete, wooden or asphaltic substrates to yield a coating of excellent physical properties. The chemically modified asphalt and the normal asphalt can be blended prior to emulsification, can be separately emulsified and mixed to form a blended emulsion, or can be individually emulsified in the same emulsification medium.

Asphalt coating composition

A knitted unidirectional mat of glass rovings, factory coated with elastomeric modified asphalt, is used to reinforce a crack in an old road before applying a new layer of asphalt-based pavement.

Road repair material of knitted unidirectional glass roving mat coated

Protective coating solutions for cementitious substrates are disclosed which comprise a minor amount of a cyclohexane based organic solvent on a major amount of an asphaltic material. The asphaltic material is a blend of asphalt with the reaction product of asphalt, a vinyl aromatic monomer, a rubber and an unpolymerized acrylamide.

Chemically modified asphalt protective coating solution and concrete

A chemically modified asphalt prepared by reacting an asphalt with a polymerizable vinyl monomer (e.g., styrene) and a rubbery polymer including reclaimed rubber (either natural or synthetic) whereby the rubbery polymer is chemically integrated with the asphalt. The chemically modified asphalt compositions of the invention can be used in the treatment of glass fibers as well as in road paving applications and the like.

Chemically modified asphalt compositions

An improved process for forming an acoustical or thermal insulating fibrous glass product is provided, wherein the binder employed is asphalt and the asphalt is converted into a substantially insolubilized form.

Glass insulation with an insolubilized asphalt binder

Combination of solvent solutions of chemically modified asphalts and oil based paints compatible therewith are disclosed as coating materials.

Asphalt based coatings

Glass fibers, either in the form of individual filaments or bundles of glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with an organo metallic compound in the form of an orthoester or an organo metallic boron compound. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.

Boron-modified asphalts

A reinforced composite formed of a bitumen, an elastomer or a plastic reinforced with a filler containing a coating thereon in the form of a chemically modified bitumen. The chemically modified bitumen employed is one formed by reaction of a linking agent reactive with the bitumen and containing groups reactive with the filler so that the chemically modified bitumen undergoes a chemical reaction with the filler to thereby intertie the coated filler with the continuous phase.

Reinforced composites

A bitumen composition modified with an organo silane in which a bitumen such as asphalt is reacted with an organo silane containing ethylenic unsaturation or an organo silane containing at least one hydrogen atom bonded to the silicon atom whereby the organo silanes react with ethylenic unsaturation of the bitumen to chemically bond the organo silane to the bitumen. Also included are bitumens which have been chemically modified by reaction with steam, air, ammonia or aliphatic amines which have been reacted with a silane containing a functional group reactive with the bitumen. Bitumen compositions of the invention are preferably used in the treatment of glass fibers for use as reinforcement in asphalt systems.

Asphalt compositions modified with organo silane compounds

Glass substrates are provided, for example, glass fibers, with a substantially solvent insoluble coating of asphalt.

Glass substrates with an insolubilized asphalt coating

An asphalt-modified polyester composition comprising an asphalt which has first been reacted with a polycarboxylic acid or anhydride and a polyalcohol; the modified asphalt is then reacted with a polyester and a vinyl aromatic monomer to produce a molding composition which is ideally suited for combination with a glass fiber reinforcement in the molding of rigid bodies reinforced with, for example, glass fibers.

Modified asphalt compositions

Chemically modified asphalt compositions prepared by reaction of asphalt with ammonia, a polyamine or an aromatic diamine. The chemically modified asphalt compositions of this invention are particularly well suited for use in the treatment of glass fibers as reinforcement for asphalt matrices.

A chemically-modified asphalt composition formed by reaction of an asphalt, a polycarboxylic acid or anhydride and an organic polyalcohol. The resulting polyester-modified asphalt composition can be cross linked using a vulcanizing agent to form hard rigid bodies which can be reinforced with reinforcements and/or fillers, notably including glass fibers.

Homogeneous, substantially single phase, stable solutions of the reaction product of asphalt, a vinyl aromatic monomer, and a rubbery polymer are provided. These solutions may be sprayed onto metal surfaces to provide corrosion resistant coatings thereon and also coatings which have a sound dampening quality. The solvent employed to form the solution is a mixture of xylene and Stoddard solvent or a mixture of xylene, Stoddard solvent and heptane or hexane, or a mixture of heptane and hexane.
