Emulsified Asphalt

A suspension or emulsion of asphalt in water.

Viscosity: Usually relatively thin; almost water-like

Remarks: Can often be used without being heated. Asphalt emulsions can be applied in the same manner as asphalts; after the water has evaporated, the asphalt hardens into a continuous film. Used for coating roadways, cement waterproofing and roofing compounds.

Pump Notes: Cast iron construction is satisfactory. Packing is the normal shaft seal. Special construction features are required depending on the particular pump design.
