ABOUT
PAVEMENT:
Asphalt
pavement is a mixture of bitumen (a liquid asphalt bonding agent)
and aggregate (bulk materials such as sand, stone, gravel, pebbles,
etc.). As the liquid in your pavement cures the pavement itself
will become harder but will still remain flexible for quite some
time, especially in high temperatures. Since Asphalt pavements are
flexible they will conform to the surface beneath them and to the
shape of things placed on them. New pavement will soften and harden
as temperatures increase and decrease. The first six to twelve months
after installation pavement will remain soft and pliable and extra
care should be taken to allow the pavement to cure.
Information
About Pavement Installation And
Selecting The Paving Option That Is Right For You:
SUB-BASE
The first and most important factor to be considered prior to the
installation of asphalt is the foundation upon which it will be
built. New asphalt should be installed on a foundation of properly
compacted crushed stone. Be sure your contractor is using a State
Approved Material such as Item #4 crushed stone. Avoid Sub-base's
such as Norlite, which consist of shale and breakdown.
If
you have clay ground conditions, it may be necessary to install
geo-textile stabilization fabric prior to installation of new sub-base.
This fabric prevents the clay from contaminating and undermining
the sub-base.
ONE
COURSE PAVING:
Best suited for residential paving where heavy vehicles will not
be placed on the pavement. Consists of a single layer of Asphalt
approx. 3" thick.
TWO
COURSE PAVING:
Best suited for commercial and residential paving where there is
the expectation of heavy vehicle use.
Consists of two layers of pavement (a binder course and a top course)
with compaction being performed after the installation of each layer.
PAVEMENT
RESURFACING:
Paving over already existing pavement. This consists of first true
& leveling any low areas in the existing pavement. Then applying
a layer of pavement approx. 1"- 1½" over the entire
area. It is important to note the new pavement will conform to the
condition of the base upon which it is placed.
