Fog seals are primarily used to “seal” a porous roadway or as the final application during a chip seal. Rejuvenating seals are typically applied to roadways that are 2-4 years old with minor cracking. The purpose is to “rejuvenate” the roadway by adding the naturally occurring “oils” back into the roadway that have oxidized out of the pavement. This adds life to the pavement and allows it to perform better and be more flexible.
Both fog seals are applied using Caltrans specifications.
