Dos and Don'ts

DO: Store between 50°F (10°C) and 185°F (85°C), depending on the intended use and specific product.

DO: Store at the temperature specified for the particular grade. Table 3.1 shows the normal storage temperature ranges.

DO NOT: Permit the asphalt emulsion to be heated above 185°F (85°C). Elevated temperatures evaporate the water, changing the characteristics of the asphalt emulsion.

DO NOT: Let the emulsion freeze. This breaks the emulsion, separating the asphalt from the water. The result will be two layers in the tank , neither of which will be suited for the intended use, and the tank will be difficult to empty.

DO NOT: Allow the temperature of the heating surface to exceed 212°F (100°C). This will cause premature breakdown of the emulsion on the heating surface.

DO NOT: Use forced air to agitate the emulsion . It may cause the emulsion to break.

DO NOT: Allow excessive agitation by mixing or pumping.
