Rocky Road
How to guarantee a
smooth road ahead.
By Lance Luke
emember Rocky Road ice cream;
a nice frozen treat of chocolate ice
cream, nuts and marshmallows? Well,
this article is about a different type of
rocky road ... and it’s not nearly as sweet.
Based on proper maintenance,
reserve studies estimate the life cycle
of asphalt areas to be between 35 to 40
years. I deem proper maintenance to
be yearly inspections, with sealcoating
every 4 to 6 years. Maintenance
doesn’t add to the structural value
of a road, but it restores its surface,
protections it from the elements and
extends its life.
Sealcoating needs to be done on
asphalt in good condition, and failed
areas need to be cut out and patched
to full depth. Cracks should also
be sealed with either a hot patch or
cold patch sealer prior to sealcoating.
Cracks should be addressed before
they allow water to enter the subgrade
and lead to larger problems.
The service life of asphalt
is dependent upon the original
construction, traffic, drainage and
climate conditions. Timely maintenance
will help decrease the loss of
serviceability. Once water gets into the
base course and soil, there is no turning
back. Not even an overlay will help. A
total resurface job will be required.
Drainage: Correct drainage must
be taken into consideration on a
resurfacing or overlay project. Any
low or soft spots should be corrected.
Address ponding areas and make sure
the driveways have proper drainage.
Confirm elevations: The finished

grade of the new asphalt should line up
with drainage gratings, valve boxes and
driveway gates. The general thickness
of the pavement should be four inches
compacted but keep in mind that areas
of heavy truck traffic, such as garbage
trucks, may need to be “beefed up.” Or,
as an alternative, a concrete pad should
be constructed in the affected area.
Prevention: The key to extending
the life of asphalt pavement is through
yearly inspections, sealcoating every
4 to 6 years and repairing damaged
areas at the time of sealcoating. A new
driveway and parking area will last
for years if maintained properly.
Don’t let your roadways become
a pain in the asphalt. Fix the cracks
before they soon become potholes.
And sealcoat often.
