Sealcoating
When it comes to protecting your asphalt pavements against deterioration.
There is no greater value than a correctly applied coal tar emulsion.
Sealcoating substantially reduces maintenance costs and at the same time extends
the life of asphalt pavements by as much as 300%. The cost of sealcoating is
truly a minor expense when compared to the cost of pavement replacement.
 
A few of the benefits of sealcoating:
Reduces Costs & Increases Value:
- Most importantly all the benefits below reduce the cost of
maintaining your asphalt pavement and increase it's usable lifespan. With
costs rising dramatically for asphalt nowadays preventative maintenance
saves dollars for pennies. More than ever in today's economy you can't
afford not to sealcoat and seal any cracks properly to prevent
moisture intrusion. The intrusion of moisture into asphalt pavement
structure accelerates it deterioration and is strongly related to pavement
distress. The sealing of well-cured asphalt prevents the seepage of moisture
from snow and rain, thus preventing damage from freeze-thaw cycles.
Appearance:
- The dark charcoal black color of newly applied pavement sealer
improves the appearance of new and old asphalt pavements. Unprotected
asphalt surfaces gradually lose their rich black color due to oxidation and
weathering. We can preserve the smoothness and resilience of asphalt
surfaces and help hide rough spots, small cracks, patches and some surface
depressions. Pavements coated with a pavement sealer look cleaner because
rainfall washes dirt and debris easily from the smooth, non-porous surface..
Traffic lines become more visible.
Stops Oxidation:
- Actinic rays in sunlight combined with pollutants from exhaust can
oxidize the asphalt cement oils in asphalt pavements, causing brittleness
and resulting loss of aggregates which may rob up to 50% of the original
asphalt thickness in just five years. A pavement sealcoated will resist
oxidative degradation and retain its value.
Prevents Water Penetration:
- The intrusion of moisture into asphalt pavement structure
accelerates its deterioration and is strongly related to pavement distress.
The sealing of well-cured asphalt prevents the seepage of moisture from snow
and rain, thus preventing damage from freeze-thaw cycles.
Resists Fuel Penetration
- Resists gas, oil, salt and chemical penetration. Asphalt is a
petroleum derivative, soluble in distillates such as gas, jet fuel and oil
drippings. Sealcoating prevents damage from distillates and chemicals.
How does Constant Asphalt provide these benefits in the best, most
cost-effective manner?
We only use the best coal tar sealant (produced by
SealMaster the Nations #1 Sealcoating Mfg.) that is specifically designed
to protect bituminous pavements. It forms a tough, durable and flexible coating
that protects asphalt pavements from the damaging elements of weather, water,
salts, gas and other petro-chemicals.
Application is more than just getting the sealer on the pavement-the best
products can be ruined by improper application.
Asphalt sealer must be applied to structurally sound pavements by experienced
applicators. Asphalt pavement should be protected by two coats; however, the
quantities and coverage rates must conform to manufacturer's detailed
specifications. Average coverage rates are 0.18 to .20 undiluted gallons per
square yard. A latex rubber additive and silica sand must be added to increase
traction and durability.
Why do we use Coal Tar Pavement Sealer?
- It was the original pavement sealant formula developed in 1933 and
refined over all these years for optimum protection. Sealcoating with an
asphalt based sealer is like wearing a cotton raincoat to protect a cotton
shirt; of course you would wear a rubber raincoat, something that
protects what's underneath
Coal Tar Pavement Sealer Exhibits Outstanding Fuel Resistance
Our Mixing Procedures (Manufacturer's specifications):
(Based on 100 gallons of Concentrate)
Coal Tar concentrate 100 gallons
Water 30-40 gallons
Sealer 1/2Top Tuff 1/2 FSAPolymer Additive 1-2 gallons
Sand (40-70 mesh AFS) 300-500 lbs.
Mix thoroughly in agitated tank and apply by squeegee,brush, or spray.
Material Requirements (coverage):
One gallon of Coal Tar Concentrate will cover approximately 100-120 square
feet (11.1 to 13.3 square yards) per coat when properly mixed and applied.
Note:
Coverage rate may vary due to pavement age, porosity, and method of
application.

Crack Sealing
Cracks in your asphalt are potholes waiting to happen. As asphalt ages
cracks can develop from age or there can be other causes.
But whenever you have a crack moisture will get through the cracks and into the
base material degrading the base. When that happens it creates weak areas and
that can lead to pavement failures. In the winter the moisture can freeze
causing accelerated failure. In the summer incompressible materials like stones
can get in cracks and as the heat causes pavement to expand the cracks can't
move causing the cracks to expand and "run" making the problem worse--it's
a vicious cycle destroying your pavement bit by bit that only proper sealing can
stop.
We offer Hot-Pour Crack Sealing. Hot crack sealing is the preferred
method of crack sealing (Federal research data SHRP-P106). We offer a full year
warranty on hot crack sealing work.
Our Warranty:
One year on material and workmanship. But expect it to out live the
warranty by 2 or more years.
