Methods and systems for efficiently manufacturing modified asphalt materials include agitating a base asphalt at a high shear rate using an in-line mixer while simultaneously exposing the asphalt to oxygen by blowing an oxygen-containing gas at a high gas flow rate through openings in the in-line mixer and heating the asphalt at an elevated temperature.

Methods and systems for manufacturing modified asphalts

A method for modifying asphalt comprises blowing an oxygen-containing gas through a base asphalt at a high gas flow rate while simultaneously agitating the base asphalt at a high shear rate and at an elevated temperature for a period of time that is effective to substantially improve at least two paving properties of the base asphalt. In preferred embodiments, modified asphalts are produced having both substantially improved rutting resistance and substantially improved fatigue resistance as compared to the base asphalt.

Methods and systems for modifying asphalts

Methods and systems for efficiently manufacturing modified asphalt materials include agitating a base asphalt at a high shear rate using an in-line mixer equipped with a rotor-stator mixing tool while simultaneously exposing the asphalt to oxygen by blowing an oxygen-containing gas at a high gas flow rate through openings in the rotor-stator mixing tool and heating the asphalt at an elevated temperature.

A fluid or semifluid additive composition useful for asphalt paving comprises between about 10% and about 50% crumb rubber, about 10% and about 50% petroleum hydrocarbon having at least about 50% aromatics, between about 10% and about 50% surface active clay, and water, by weight.

The invention provides an improved method of transparentizing a paper substrate to produce a translucent area or 'window' through which information and data are displayed. The method of the invention applies a transparentizing material to a preselected application site of the paper substrate, and exposes the transparentizing material to heat for a predetermined period of time to help facilitate penetration of the transparentizing material into the paper substrate and prevent migration of the transparentizing material from the application site. The rate of penetration of the transparentizing material into the paper substrate reduces the time and increases the efficiency of the transparentizing process. The invention also provides a paper substrate and a one-piece paper assembly in which a translucent area or 'window' is formed according to the method of the invention.

A method of preparing an asphalt emulsion composition comprises preparing an aqueous emulsion of a synthetic polymer and asphalt mixture, and blending the aqueous asphalt/polymer emulsion with reclaimed rubber particles wherein the ratio of polymer:rubber particles is between about 1:2 and about 1:20, by weight, respectively, at ambient temperature. The final composition may also contain one or more solids selected from a rheological agent, gilsonite, carbon back, surface active clay and polymer fibers, and mixtures thereof.

A fluid or semifluid additive composition useful for asphalt paving consists essentially of between about 10% and about 50% crumb rubber, about 10% and about 50% petroleum hydrocarbon having at least 55% aromatics, between about 10% and about 50% surface active clay, and water, by weight.

A method of preparing an asphalt emulsion composition comprises mixing an aqueous asphalt emulsion, water, latex rubber, and a solids mix composition comprising reclaimed rubber particles passing through a 40 mesh U.S. series sieve and one or more solid addends selected from the group consisting of a rheological agent, gilsonite, carbon black, surface active clay and polymer fibers, and mixtures thereof and wherein the ratio of latex rubber:rubber particles is between about 1:1 and about 1:10, by weight, respectively, and mixing the components at substantially ambient temperature.

Method for preparing improved asphalt emulsion compositions

A method of preparing an asphalt emulsion-rubber paving composition comprises combining an aqueous asphalt emulsion, water, latex rubber, minus 40 size rubber particles, and a thickening agent, mixing said materials at substantially ambient temperature to form a substantially homogeneous liquid composition, adding to said liquid composition between about 5 and about 15 pounds of aggregate per gallon of said gallon, and mixing the components at substantially ambient temperature to form such paving composition.

Asphalt emulsion-rubber paving composition

A base stock composition comprises a blend of gilsonite, asphalt and a rubber latex residue. The base stock may be used alone as a paving material or emulsified to form a gilsonite emulsion having a variety of uses.
