Abstract: An asphalt-based, cold paving/coating formulation that provides increased flexibility with respect to the choice of aggregate types, asphalt emulsion types, type and amount of the surfactants used to produce the asphalt emulsion, asphalt emulsion pH's and application temperature's than conventional cold paving/coating formulations while providing good mix times and curing behavior. The asphalt-based formulation can be formed by mixing water; an asphalt emulsion; at least one first compound in aqueous solution selected from the group consisting of alkali metal salts, alkali metal hydroxides, ammonium salts, and ammonium hydroxide; at least one second compound in aqueous solution selected from the group consisting of Group IIA salts, Group IIIA salts, Group IIIB salts, copper salts, zinc salts, cadmium salts, manganese salts, iron salts, cobalt salts, and nickel salts; and optionally aggregate. Also, a method of preparing an asphalt-based formulation using these components.

Abstract: The present invention is a method of incorporating a water insoluble organic chemical into a styrene-butadiene rubber latex dispersion and the resulting styrene-butadiene rubber latex dispersion. A styrene-butadiene rubber latex dispersion is provided comprising an aqueous phase and a disperse phase, with the disperse phase including particles of styrene-butadiene rubber. An organic solvent that is miscible in water and the water insoluble organic chemical are added together to the styrene-butadiene rubber latex dispersion. The addition of the water-miscible organic solvent allows the water insoluble organic chemical to pass from the aqueous phase into the disperse phase thus limiting separation of the water insoluble organic chemical from the latex dispersion. The resulting SBR latex has increased properties over conventional latices that use the same amount of the water insoluble organic chemical but that do not include the water-miscible organic solvent.
