Fog seal is a single application, typically light, of emulsified asphalt to an existing asphalt surface. This type of maintenance treatment can be valuable aid to renew weathered (oxidized) asphalt surfaces and improve the surface appearance, seal minor cracks and surface voids, and inhibit raveling.
2 to 4 years of life extension depending on the existing conditions
Minor surface cracks
Raveling (due to segregation or poor compaction)
Protects the pavement structure from moisture intrusion and oxidation
Improves pavement life and may delay the need for major maintenance or rehabilation
Improves road safety by enhancing color contrast between pavement surface and road markings
