Fog Seal

A fog seal is a light application of a diluted slow-setting bitumen emulsion to the surface of an aged (oxidized) pavement surface. Fog seals are low-cost and are used to restore flexibility to an existing HMA pavement surface. They may be able to temporarily postpone the need for a surface treatment or non-structural overlay.

The uses of fog seal are..
  • Seal very small cracks and surface voids
  • To renew old asphalt surfaces those have become dry and brittle over age
  • It can help delay the need for major maintenance when applied in a timely manner
