The
nature of asphalt & the necessity of periodic,
preventative maintenance
Asphalt pavement is composed of
aggregate of various sized stone, sand, and a binding element,
known as asphalt cement. The asphalt overlay functions as a
“cover” for the overall pavement design. As the strength and
stability of the foundation determine the overall life and
performance of any traffic bearing surface, a durable, resistant
top layer is as necessary in order to shield the underlying base
from water penetration. Yet, it is just as imperative that the
binding element maintain its flexibility to endure
temperature changes.
The deteriorating effects of
weather, oxidation through sun exposure, and harsh chemical
deposits from leaky automobiles over time break down the binding
property of the asphalt cement. The result is unraveling of the
pavement, or an “alligator” effect, leaving the sub-base
vulnerable to water penetration.

Seal Coating
Our seal coating process forms a waterproof, resilient layer of
protection creating a barrier against the degenerative effects
of time, weather and harmful chemicals.
It is preventative maintenance which serves to protect your
original investment.
The application of seal coat:
 |
seals in the
vital binding element of the asphalt mix, preventing
pre-mature breakdown of its structure |
|
|
acts as a
wearing coarse for the overall pavement design |
|
|
protects the
original investment of the new pavement by substantially
increasing the life of the pavement, and reducing the need
for costly repairs or untimely resurfacing |
|
Crack filling
Open cracks and joints in pavement can result in extensive
pavement repairs. Leaving these voids exposed over time results
in new crack formation at an accelerated rate. By sealing cracks
and joints, the penetration of surface water, stones, and sand
into the pavement’s sub-base is restricted, maintaining its
structural capacity and preventing further degradation.
