Chipseal
A chip-seal-surfaced pavement can optionally be sealed with a top layer, which is referred to as a fog seal or enrichment The introduction of polymer-modified bitumen and emulsion binder has increased chipseal's ability to prevent crack reflection and improve stone retention by improving the properties of.

Fog Seals
A fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged (oxidized) pavement surfaceFog 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.

Chip Seal Treatment Types
A chip seal gets its name from the “chips” or small crushed rock placed on the surface Asphalt emulsions used in chip seal applications contain globules of paving asphalt, water, an “emulsifying agent” or surfactant, polymer, and sometimes a “rejuvenator” Soap is a common form of a surfactant.
