There is provided a blend of a slow setting asphalt emulsion with rapid setting emulsion containing the reaction product of asphalt, an acrylamide, a vinyl aromatic monomer and a rubbery polymer.

Blend of rapid set asphaltic emulsion with slow set asphalt emulsion

The adherence between an asphalt and aggregate is increased by incorporating into the asphalt a vinyl monomer and an alkenyl azabenzene.

Additives for hot mix asphalt

A method for reclaiming used asphalt by mixing it with a chemically modifying system consisting of a polymerizable vinyl monomer and an alkenyl azabenzene.

The adherence between an asphalt and aggregate is improved by including in the combination styrene and an acrylamide.

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

The inner side of an exterior wall of an existing building is insulated by installing floor-to-ceiling panels along the wall, the panels having glass windows where the wall has windows.

Insulation system for inner side of exterior wall

An improved chip seal method for treating pavement with aqueous asphaltic emulsions is provided wherein the emulsion is a blend of a conventional emulsion adapted for an aqueous asphaltic emulsion is provided in which the dispersed asphaltic material is the prereacted reaction product of asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), an acrylamide, a vinyl aromatic monomer and an elastomer.

Chip seal technique employing blends of asphaltic emulsions

An aqueous asphaltic emulsion is provided in which the dispersed asphaltic material is the prereacted reaction product of asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), an acrylamide, a vinyl aromatic monomer and an elastomer.

Aqueous emulsions of acrylamide and rubber modified asphalts

An improvement in pavement surface-treating methods is provided of the type wherein a slurry seal composition is applied to the pavement the composition comprising aggregate in a slow setting asphaltic emulsion. The improvement resides in combining with the slow setting asphaltic emulsion in effective breaktime decreasing amount of an emulsion containing a chemically modified asphalt which is the prereacted reaction product of an acrylamide, asphalt having a viscosity of less than 120,000 cps (at 140.degree. F.), a vinyl aromatic monomer and a rubbery polymer.

Slurry seal method using acrylamide and rubber modified asphaltic

A laminated wall for a feeder for supplying streams of molten glass to be attenuated into filaments is provided comprising: a refractory metal core having an oxygen impervious, precious metal sheath intimately bonded thereto by hot isostatic pressing to form a laminate, said laminate having at least one aperture extending therethrough adapted to permit said molten material to flow therethrough.

Method and apparatus for forming glass fibers

A laminated wall for a feeder for supplying molten streams of glass to be attenuated into fibers is provided comprising a refractory metal core having an oxygen impervious, precious metal sheath intimately bonded thereto by hot isostatic pressing, said core having an insert therein having at least one orifice extending therethrough adapted to pass said molten material therethrough.

Feeder for forming glass fibers and method for making feeder

Chemically modified asphalts having utility for road construction, repair and maintenance as well as coating for various substrates, including cementitious substrates, glass and metal are provided. These asphalts are the product produced by reacting an acrylamide, asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), a vinyl aromatic monomer and a rubbery polymer.

Easily emulsifiable acrylamide and rubber modified asphalts

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

A feeder for supplying molten streams of glass to be attenuated into fibers is provided comprising a refractory metal core; an oxygen impervious, precious metal sheath and an intermediate diffusion barrier layer intimately bonded together by hot isostatic pressing to form a unitary laminate, said laminate having inserts having orifices extending therethrough adapted to establish streams of molten material for attenuation into filaments.

Cationic chemically modified asphalts having utility for road construction, repair and maintenance as well as coating for various substrates, including cementitious substrates, glass and metal are provided. These asphalts are the product produced by reacting an acrylamide, asphalt, a vinyl aromatic monomer and a rubbery polymer.
