A fog seal is designed to coat, protect, and/or rejuvenate the existing asphalt binder. The addition of asphalt will also improve the waterproofing of the surface and reduce its aging susceptibility by lowering permeability to water and air. To achieve this, the fog seal material (emulsion) must fill the voids in the surface of the pavement.
Asphalt Emulsions Scott Dmytrow 2017-02-16T11:06:16+00:00 Asphalt emulsion is a combination of three basic ingredients; asphalt, water, and small amounts of emulsifying agent. In the same process, these components are introduced into a mechanism known …
A fog seal is a light application of a diluted slow-setting asphalt 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.
Fog Seal Is a mixture of aggregate, asphalt emulsion, Fog sealing is a method that is used to lock in chips in a chip seal or to coat a new hot mix surface to lock in fines and fill surface voids. It is not used for aged pavements usually for this a rejuvenation spray such as Styraflex™ ERA™ is recommended.
Types of Seal Coats Fog Seal Is an application of a dilute emulsion without an aggregate cover. Its purpose is to seal and enrich an under-asphalted surface or to tighten and waterproof an open texture pavement. Fog seals can also be used as pre-seals. Generally a Cationic Slow Seal (CSS-1) or CSS-1h emulsion is
A fog seal applied for the purpose of increasing the asphalt content of under-asphalt-ed, usually newly constructed, surfaces or chip seals. Flush coats are treated herein as fog seals. 11.2.4 Emulsion Break The initial separation of the wa ter from the emulsion, that can be detected by a marked
CRF ® Restorative Seal: CRF ® is the right asphalt repair choice once a pavement gets distressed to the point where rejuvenation alone is not enough and you need to begin to think of corrective maintenance. Applied as a cold cationic emulsion, the material will seal cracks, fill raveled areas, and help rejuvenate the existing pavement.
Fog Seal Application 2 Materials Checks Asphalt emulsion selection: type and dilution rate. The emulsion is from an approved source (if required). The emulsion is sampled and submitted for testing (if required). The water to be used is compatible with the emulsion. The emulsion temperature is within application temperature specifications.

A chip seal is a two-step process which includes first an application of asphalt emulsion and then a layer of crushed rock to an existing asphalt pavement surface. A chip seal gets its name from the "chips" or small crushed rock placed on the surface.
eFog is a rejuvenating fog seal from Ergon Asphalt & Emulsions that can correct more severe distresses than a conventional fog seal. Also, it extends the life of open graded friction courses and worn chip seal surfaces by 2-3 years, allowing for 7-10 year lifecycles.

A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. Micro-Surfacing is similar to slurry seal, except it hardens quicker.

Fog seal can be used in both #high-traffic and low-traffic roadways, where depending on the breaking time of the bitumen emulsion, the traffic must be avoided for 2-3 hours.…
CRS-1 is a cationic emulsion primarily used as a tack coat. The emulsion used as a tack coat (either as is or diluted 50% with water) or fog seal (diluted 50% with water) and applied with a distributor. CRS-1 consists of specially refined asphalt dispersed in water without the use of clay or similar substances as emulsifying or stabilizing agents.

Fo g Seal is a specifically designed asphalt emulsion used on an existing "sound" paved road surface. It can be used on hot mix asphalt as a pavement rejuvenator, thus extending the life of the pavement. Following application the aged pavement appears as an up to date paved surface.
Fog Seal A fog seal is an application of asphalt emulsion sprayed onto a pavement surface with or without a sand cover (figure 3). The emulsion is diluted to the proper consistency in order to get complete coverage on the roadway but not be too thick to cause a slippery surface.
