| 摘要 |
The present invention is an asphalt-based, cold paving 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 formulations while providing good mix times and curing behavior. The present invention includes an asphalt-based formulation formed by mixing aggregate; 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; and 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. The present invention also includes a method of preparing an asphalt-based formulation using these components.
