Abstract: Compositions, methods, and products that improve the adhesion of markings, for example, thermoplastic road markings, to substrates are disclosed. In some embodiments, such thermoplastic road markings include, but are not limited to, striping, solid lines, broken lines, and other traffic safety or informative markings placed on a substrate.

Abstract: A penetrating base oil emulsion and a method of using the penetrating base oil emulsion to fill voids below the surface of an asphalt pavement. The penetrating emulation further being water resistant so as not to be washed off a pavement surface by water after being applied to the pavement. The penetrating base oil emulsion can also rejuvenate the surface of the asphalt.

Abstract: Asphalt binders and bituminous compositions comprising additives such as naphthenic acid esters. In certain embodiments the ester compounds may be useful as rheology modifiers for use in bituminous binders in road paving applications.

Abstract: Methods and compositions useful for cleaning the lines used during manufacturing processes are disclosed. In certain embodiments, the methods and compositions may be particularly useful in the manufacture of colored paints or coatings or in the use of colored paints or coatings, for example, in the manufacture of finished automobiles.

Abstract: Asphalt binders and bituminous compositions comprising oligomeric additives such as alkoxysilane oligomers compounds. In certain embodiments the oligomeric compounds may be useful as adhesion promoters for use with asphaltic bitumens and aggregates in road paving applications.

Abstract: A method of separating sludge which involves adding an insoluble mineral colloidal suspension into an industrial sludge to destabilize the industrial sludge and separating destabilized components of the industrial sludge. The insoluble mineral colloidal suspension includes magnesium hydroxide. In an alternative embodiment dry finely divided magnesium hydroxide can be added and then dispersed into an industrial sludge. Conventional flocculants and/or coagulants can also be added. Conventional physical separation processes can be used to separate the destabilized industrial sludge.

Abstract: Method of reducing calcite formation from solubilized calcium forms in aqueous effluent streams, including the reduction or removal of solubilized forms of nickel, selenium, sulfate, and magnesium.

Abstract: A void filling asphalt emulsion and a method of using the void filling asphalt emulsion to fill voids below the surface of an asphalt pavement. The void filling emulsion is prepared by forming a base asphalt emulsion having about 45 to 75 wt. % of an asphalt content, and combining the base asphalt emulsion with a surface tension reducing solution to produce a void filling asphalt emulsion that has about 25 to 50 wt. % of an asphalt content. When applied to an asphalt pavement the void filling emulsion penetrates into the asphalt pavement and fills voids in the asphalt pavement. The void filling emulation further being water resistant so as not to be washed off a pavement surface by water after being applied to the pavement.

Abstract: A method of sealing pavement joints includes the steps of dispensing a first band of void reducing joint composition on a substrate. Applying a first pass of pavement over at least a portion of the void reducing joint composition. Dispensing a second pass of void reducing joint composition on the substrate. Applying a second pass of pavement of the second band of void reducing joint composition and against an edge of the first pass of pavement.

Abstract: Methods of treating leachates in rock piles. Exemplary leachates include neutral aqueous leachates containing selenates and nitrates, said leachates being found in waste rock piles from coal mining operations. In certain embodiments, the method includes introducing an inert gas to the lower section of the rock pile, and allowing bacteria indigenous to the mining site to reduce the selenates and nitrates to selenium and nitrogen, respectively.

Abstract: A method for reducing the mutagenicity of polycyclic aromatic compounds (PAC's) having one or more bay regions which involves alkylating the PAC's with an alkylating agent in the presence of a catalyst to lower the mutagenicity down to as much as about 0.1. The resulting alkylated polycyclic aromatic compounds retain their physical and chemical properties for safe industrial use including as rubber processing oils, inks, etc.

Abstract: A method of separating sludges which involves adding an insoluble mineral colloidal suspension into an industrial sludge to destabilize the industrial sludge and separating destabilized components of the industrial sludge. The insoluble mineral colloidal suspension can be adding into the industrial sludge or formed in situ therein by components into the industrial sludge that react together therein to form the insoluble mineral colloidal suspension.

Abstract: A binder composition for asphalt pavements that includes: an asphalt binder; an elastomeric polymer; a wax modifier; and optionally at least one of: i) fumed silica or fumed alumina; and ii) a saponified fatty acid and a resin acid gelling compound. The composition is applied as a tack coat and/or a stress absorbing membrane interlayer and is non-tracking.
