eFog Rejuvenating Fog Seal

Extend Pavement Service Life and Restore Durability

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.

eFog contains a polymer-modified asphalt base that provides a denser film thickness for increased durability and resistance to tracking. As a rejuvenator, eFog restores essential elements in the existing asphalt, improving its overall quality and durability. Once it has cured, traffic can usually return to the pavement within 1.5 hours.

Ideal for oxidized or raveled pavements, eFog is one of the most cost effective ways to protect and extend the life of a road's surface.

eFog Rejuvenating Fog Seal

Benefits:

  • 2-3 year service life extension
  • Corrects severe distress
  • Repeat applications possible
  • Quick return to traffic (typically within 1.5 hours)
  • Increases pavement durability
  • Resistant to tracking
  • Can be used as a bond coat
  • Can be used as a cold pour crack filler

 

What is a fog seal?

eFog is a Rejuvenating Fog Seal that can correct more severe distresses than
a conventional Fog Seal. It can provide open graded friction courses with a
2-3 year lifecycle extension without reducing permeability, and offers equally
effective results on worn chip seal pavements. In addition to its use as a
rejuvenating fog seal, eFog can be used as bond coat or cold pour crack filler.

 

Issues eFOG fog seal can correct?

eFog can correct roadways and shoulders exhibiting:

  • Raveling
  • Oxidation
  • Pitting
  • Cracks up to 1/8”
  • Asphalt lean mixtures

 

Features

eFog is ideal for use on oxidized or raveled pavements. It replaces light end
fractions lost from the asphalt mix during manufacture, storage, placement
or service. Its polymer-modified asphalt base provides a denser film thickness
for increased durability and resistance to tracking. As a hybrid emulsion,
it provides the benefits of both a rejuvenator and a conventional asphalt
emulsion product. Once eFog has cured, traffic can typically return to the
pavement within 1.5 hours. If a very quick return to traffic is necessary, an
application of 2-4 lbs/yd2
of sand can be applied.

 

How to apply fog seal

eFog is applied through an asphalt distributor at rates typically between
.06 - .13 gal/yd2

 

Conventional Fog Seal

Conventional Fog Seal is a light application of diluted asphalt emulsion that
is spray applied to an existing asphalt surface, protecting it against traffic
and the environment. Fog Seal is applied to roadways that have a good base
structure, but exhibit the earliest signs of distress. Although it is a first-sign-ofdeterioration application, its effectiveness improves with repeat applications.
As a truly preventive maintenance treatment, it reinforces what’s already in
place and increases safety by delineating driving lanes

 

Issues Fog Seals Can Correct?

Fog Seals can correct city streets, interstate shoulders, or airport runways
exhibiting:

  • Oxidization
  • Raveling
  • Pitting
  • Cracks < 1/8 inch

 

Conventional Fog Seal Features

Fog Seals are the most cost effective preservation treatment available.
They seal hairline cracks and can prevent raveling on open graded surfaces,
while providing a 1-3 year extension to a pavement’s existing service life.
On new chip seal construction, Fog Seals improve chip retention and
provide a finished HMA appearance. On older chip seal surfaces, Fog Seals
stop aggregate loss and extend the remaining service life. Fog Seals should
be diluted before shipment to provide consistent asphalt residue rates,
temperature control, improved stability and better application coverage.
Cure times vary due to climate, application rate and surface condition, but
are generally between 1-3 hours.
