A pressure-sensitive adhesive is disclosed which is prepared by hot melt blending paving grade asphalt, a depolymerized virgin rubber, a terpene resin, and a vulcanizable, non-depolymerized styrene-butadiene copolymer. These adhesives are especially useful in forming membranes by coating one side of an asphaltic based coated reinforcement with these adhesives. They are useful for highway repair and maintenance purposes and for waterproofing and show good adhesion to cementitious, for example asphaltic concrete or Portland cement concrete, substrates.

Blended pressure-sensitive asphaltic based adhesives

A chemically modified asphalt composition is provided which is especially adapted for use in the repair and maintenance of highways. The composition is a reaction product of a high oil asphalt, a vinyl aromatic monomer and a rubbery, or elastomeric, polymer.

Chemically modified high oil asphalt

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

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

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.

A chemically modified asphalt prepared by reacting an asphalt with a polymerizable vinyl monomer (e.g., styrene) and a rubbery polymer whereby the rubbery polymer is chemically integrated with the asphalt. The chemically modified asphalt can be, if desired, further cross linked by reaction with a cross linking agent such as a polycarboxylic acid, an organic isocyanate or an organic polyepoxide. 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

A rubber modified asphalt composition prepared by reacting a bituminous material with a polymerizable aromatic monomer and a rubbery polymer whereby the rubbery polymer is chemically integrated with the asphalt. The rubber modified asphalt compositions of this invention can be used in the treatment of glass fibers as well as in road paving applications, roofing applications and the like.
