Jul 01, 2017· seal may be the best suited for roads with high traffic volumes. A chip seal is laid in the conventional manner. After the chip seal has cured, the loose cover stone is removed. Then the slurry is applied over the seal to fill the voids between the cover stones. Chip Seal A chip seal is an application of asphalt followed with an aggregate cover.

Fog Seal. Fog Seal is an emulsion diluted with water that is sprayed immediately after a chip or scrub seal to help retain aggregate. It provides a black surface that helps with short term snow and ice melt off, and makes line striping more visible, enhancing safety.

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.

The fog seal will take another half day to complete.

Fog Seals are also extremely effective complements to new and aged chip seal surfaces. The liquid asphalt secures all the cover stone from the chip seal process and locks it into place. This technique produces a black surface (helpful for rapid snow melting) for those that prefer a black road and aids in the prevention of water infiltration.

Chip Seals with Fog Seal - Delay times As per spec, complete application of the fog seal within 48 hours of the application of chip seal, but not on the same day as the application of chip seal.

1988). Asphalt emulsion fog seals are also useful in chip seal applications to hold chips in place in fresh seal coats. These are referred to as flush coats in California. This can help prevent vehicle damage arising from flying chips. The Asphalt Institute also adds that fog seals can seal small cracks (Asphalt Institute, 1999a).

Fog seal is the application of a thin layer of emulsified asphalt to the existing surface, which seals narrow cracks, restores pavement flexibility, and most importantly restores the underlying pavement structure. Fog seal is generally applied to newer streets that do not require more significant methods such as Chip, Slurry, and Friction Seal.
