Benefits of Sealcoating
WHY SEALCOAT?
Just as you paint the dapboards on a new house to seal up and protect
the structure, sealcoating a sound pavement will cause it to have a much
longer life than that of an unsealed pavement. Even on a weak pavement,
sealcoating will preserve water and oxidizing effects of the sun, salts,
and petroleum spillage. This coating preserves the pavement surface, and
the asphaltic and aggregate layers will remain dry and in place.
One of the most popular pavement coatings in use today is a coal tar
pitch emulsion fortified with liquid latex rubber. Coal tar is a closed
ring hydrocarbon which essentially does not oxidize when exposed to
weathering or chemicals that commonly come in contact with asphalt
pavement.
Now, lets once again summarize the benefits of coal tar.
BENEFITS OF COAL TAR:
Easy to apply
Outstanding resistance to detergents used to clean pavements subjected
to heavy fuel, oil or grease spillages.
Excellent resistance to water.
Unexcelled flexibility over a wide temperature range.
Superior weathering ability.
Non-scuffing under normal conditions.
Readily mixed with sand where a non-skid surface or increased traction
is desired.
Extends the service life of asphalt pavements.
Dries to a velvety black color.
Lends ease to cleaning and maintenance of asphalt.
Adds safety by minimizing loose stone aggregate "roll" out.
Can be striped with water emulsion paints after the film is cured.
Coal tar emulsion sealer is intended to be used only as a protective
coat and not as a repair, leveling material or wearing surface. Sealer
is only as good as the bituminous pavement to which it is applied. It
will not prevent the cracking of bituminous pavements caused by
excessive voids, poor mix stability, poor compaction or low use areas.
It should be applied to durable bituminous pavements which are made with
an asphalt cement having a penetration grade that meets the climate and
usage requirements of the pavement in point and properly constructed
over a sound and well drained base. Where the sealer is applied over
anything less, any cracks that will occur will be magnified by the
sealer's uniform velvet texture.
NOTE: Although the sealer exhibits excellent protective and wearing
qualities, periodic resealing is necessary in heavy traffic areas since
the film is a surface treatment and subject to wear.
The Coal Tar Emulsion Sealer used should meet requirements set forth in
Federal Specification RP-355e, Coal Tar Emulsion.
WHY ASPHALT PAVEMENTS DETERIORATE
Properly designed and constructed asphalt pavements rarely deteriorate
from the traffic. Surface wear is primarily caused by weathering,
oxidation and the destructive softening effects of gasoline, oils and
de-icers.
Our sealing application is specifically formulated to shield against the
harmful elements that lead to surface deterioration. Extend the life of
your asphalt pavement and restore that like-new look at minimal cost.
Here is what our asphalt sealing application does for your pavement:
PREVENTS OXIDATION Regular sealing applications shield against the
drying action of the sun, raveling, cracking and deterioration.
WEATHERPROOFS The accumulation of mositure in pavement structures is
probably the greatest cause of pavement damage. Sealing application
prevents water seepage into the porous asphalt structure, stopping
weather damage.
SAVE $$$$ Asphalt, a petroleum product, has tripled in cost. For pennies
per square foot, sealing application can protect your investment and
prevent costly repairs.
