Pavement Maintenance 101
Prevent large pavement repair costs with
pavement preventive maintenance.
By Cole Kaimana Millare
esurfacing a parking lot or
driveway is a large cost that not
every property manager budgets
for. However, by being proactive,
you extend the life of your
pavement and prevent large repair
costs. This proactive approach is
known as Pavement Preventive
Before getting into PPM, it’s
important to understand what your
asphalt pavement is made of and
how it degrades.
Asphalt pavement (aka asphalt
concrete, AC, hot mix asphalt or black
top) is made up of gravel, sand and
asphalt cement. The asphalt cement
is the “glue” that holds the gravel and
sand together to make your pavement.
Everything is combined in a heated
mixer, laid down on the road and is
compacted with a heavy roller.
Day 1 of your pavement’s life will
be the best condition it will ever be in.
Beginning on day 2, your pavement
will gradually deteriorate over time.
The most obvious sign of
degradation is the gradual change of
your pavement’s color from black, to
brown, and finally to gray.
Exposure to the wind, sun and
rain causes the pavement to oxidize.
The asphalt cement, or the “glue,”
weakens and can no longer hold the
gravel and sand together. This is why
you may see sand in your parking
lot even though you’re nowhere near
the beach. Raveling also takes place,
creating those pesky potholes.
Eventually, the pavement loses
its flexibility and becomes too brittle
and starts to crack. When cracks
form, it allows water to seep into the
pavement and causes larger cracks.
Eventually, your pavement will not be
able to carry any vehicle load.
Depending on how severe the
degradation is, the cost to repair—
whether it be repaving or overlay—
could be anywhere from $1 to $5 per
The concept behind PPM is to
keep your good pavement good and
not let it deteriorate. GP Maintenance
Solutions provides project
management services for pavement
maintenance and has provided tips
that can help you save both your
pavement and hard earned dollars:
Control Load On Your Pavement
Heavy vehicles carry a lot
of weight and can destroy your
pavement in a hurry. Limit access of
larger vehicles like garbage trucks and
delivery trucks on your pavement.
If possible, move garbage containers
closer to the roadway where garbage
trucks can access them without
having to drive over your pavement.
Sweeping or blowing your
pavement on a regular basis keeps
it free from hazards such as loose
aggregate and glass. Sweeping can
also help you evaluate the condition
of your pavement. If your pavement is
not cleaned regularly, debris may hide
in cracks and damaged the asphalt,
which could lead to failures that seem
to appear suddenly.
Fix Drainage Problems
Water is the main reason why
pavements fail. If water is allowed to
