A:
Apply a
"latex & sand seal" coat within six months to one year
of installation of new asphalt.
Check for
longitudinal cracks and have them filled annually.
We
recommend a seal with sand & latex every two to three
years, depending on wear. This will help prevent
deterioration of your pavement due to the sun's rays,
gasoline, traffic and the weather elements.
Q: What are some of the causes of asphalt failure?
A:
Inadequate thickness of the
pavement section to support the loads that travel across
the asphalt.
Inadequate maintenance of the pavement surface.
Weak or unstable subgrade components.
Asphalt is composed of aggregates that range in size
from tiny sand (fines) to rocks of approximately Ύ" in
diameter, and it is all held together with liquid
asphalt. Asphalt deteriorates when the "fines" are worn
away by weather and traffic. When the "fines" are worn
away, there is nothing to bind the larger aggregates
together and the surface begins to ravel. This
weakens the pavement section and eventually allows water
to penetrate the subgrade, which leads to pavement
failure.
Q: What are some reasons you should complete patching in
the summer, and not wait until the following spring to
do so?
A:
The damaged area(s) will get much
worse if not fixed before winter. By doing so, the new
patches will be able to cure until the spring , at
which time you can sealcoat the entire job.
Q: What causes the sun's rays to deplete the thickness
of virgin asphalt?
A:
The sun heats up the binder
cement, which depletes the holding characteristics of
the chemical compounds in the dried liquid asphalt. This
enables the stone to loosen up and fall away into
curbsides, ditches and storm drains.
Q: When should I seal
cracks?
A:
The sooner the better. Any crack,
which is Ό inch or wider in the pavement, will allow
moisture to penetrate to the subsurface. The goal of a
good pavement maintenance program should be to keep the
moisture from entering the asphalt pavement.
Q: What causes fatigue cracks in my pavement?
A:
It is the direct result of
excessive bending of the pavement surface. Asphalt will
fail if subjected to repetitive or excessive bending as
from vehicular traffic.
Q: Is sealing cracks cost
effective?
A:
Proper crack repair procedures can
double the life of most asphalt pavements. A surface,
which is five to ten years old, will usually need a ton
of sealant per lane mile and will last up to ten years.
Q: What is the difference
between just filling a crack as opposed to routing?
A:
Crack filling or sealing is
placement of hot material to reduce the infiltration of
water. Routing creates a reservoir. The hot material is
applied in the channel created, stopping the water from
being able to penetrate beneath the asphalt.
Q: How soon can I drive on
my lot after sealcoating is completed?
A:
Allow 24 hours drying (curing)
time after work is completed. Don't allow traffic on
your lot before the end of the 24-hour drying period.
Q: How soon can I drive on
my lot after new asphalt resurfacing is completed?
A:
Depending upon the temperature of
the day, allow 6 to 8 hours before using the new lot.
Q: What are some reasons
that concrete repairs are much more expensive than
asphalt repairs?
A:
Concrete usually requires a lot
more labor and handwork because
Tight working areas are usually
involved.
Rebar and mesh are required to
hold it together.
It
is much thicker than asphalt.
It
must be framed by hand.
Materials cost more to buy and dispose of.
There can be significant job down times while waiting
for the concrete truck to arrive and then while waiting
for the material to set up.
