Fog Seal COATINGS Fog seal "COATINGS", often referred to as Sealers, Seal Coats and/or Bituminous Seal Coats are emulsions used for a variety of applications, including: • Sealing of dense mix HMA from water and air infiltration, • Re-coating of raveling open-graded mixes, • Adhering loose aggregates on freshly applied chip seals
A fog seal is a light application to an existing surface of a slow-setting asphalt emulsion diluted with water, similar to a tack coat. It can be diluted in varying proportions up to one part emulsion to five parts water, but in most cases a one to one dilution is used. Grades of asphalt emulsion normally used for this purpose are SS-1, SS-1h, CSS-1, or CSS-1h. A fog seal can be a valuable ...

Any of the asphalt seal coat treatments could improve a pavement with raveling problems. For low-severity raveling, a fog seal could treat the problem while a chip seal or slurry seal would be needed for medium to high severity raveling. A rejuvenating treatment may also restore the binding properties of an aged pavement surface.

Use caution when the tack coat spray rate is above 0.15 gallons per square yard because of the possibility for tack coat puddling and tack coat runoff. Note 3. As spray rates are "minimum", they are rounded up to the nearest 0.01 gallon per square yard. Calculated rates are based on volume at 60 degrees Fahrenheit and 57% binder residue.
