Best Practicesto Extend the Life of your Asphalt Pavement
Asphalt pavement parking lots add value to commercial and residential lots.
Like any asset, it needs to be maintained in order to keep its value and extend its useful life.
Poorly maintained asphalt pavement is
obvious to spot.
The number one fault of agencies is that they wait until a problem develops before they address it.”
Larry Galehouse, P.E., Director of the National Center for Pavement Preservation (NCPP)

A typical asphalt pavement can last about 20 years.

+Asphalt is made up of:Rock,Sand, &Aggregates
Asphalt Cement(the binder)
UV rays break down the binder.
Without the binder, the aggregates, rock, and sand loosen and rise to the surface.
Exposure to oxygen fades the color of your pavement and makes it brittle.

Flexible
Gray(oxidized)
Brittle
Brittle asphalt pavements are more likely to CRACK
under traffic load.

Cracks will allow water to enter into the base course and cause further damage to carrying capacity.
Alligator cracks indicate a base course failure as the pavement continues to crack.
Eventually, alligator cracks
turn into potholes.
Your asphalt pavement without maintenance after 20+ years
And you mightthink about
repaving.
But repaving is pricey;
$6 - $8 per square foot.

Not to mention the inconvenience to your tenants.
This “do nothing” approach is
6 -10 times more costly than having a maintenance plan.

Pavement Maintenance Plan
1.

An asphalt pavement maintenance plan will allow you to re-allocate resources to other initiatives.
So let’s put together a pavement maintenance plan, comprised of our best practices.
BestPractices
SWEEPING & BLOWING
Sweeping keeps your asphalt clean and helps uncover any hidden cracks.
CONTROL VEHICLE LOAD
If possible, have larger vehicles access your property only if it is necessary.
Fix Drainage Issues
Proper drainage will prevent water from penetrating into your asphalt pavement.
SEALCOATING
Like sunscreen, a sealcoat prevents damage from the elements.

A sealcoat also restores the black color to your pavement.
You should sealcoat your pavement
6-12 months after it is installed.
And again every
3-5 years.
Sealcoating ranges from
40¢ - 60¢ per square foot

CRACK FILLING
Crack filling will prevent water from entering the base course.
Crack fill ranges from $5 - $10 per linear foot.Crack filling ranges
from $5 - $10 per linear foot.
POTHOLE PATCHING
Pothole patching prevents further water damage to your base course.
Pothole repair cost:
~$42/bucket
But it doesn’t FIX your base course…
To repair a pothole, the damaged area needs to be cut out and replaced.

Heat is applied to the area to soften the asphalt.

The heated area is then removed and re-compacted.

Repair cost ranges from $45 - $60 per potholebased on several potholes per site.
Remove Oil Spots
Oil spots softens asphalt, weakening its load capacity.
Oil stain removers should be used on relatively fresh stains.
Our product costs about $28 per 32oz bottle.
Wait longer and you’ll likely need to cut out the damaged spot.
The longer you wait to address a problem, the more expensive it is to fix.
That’s why it’s so important to have apavement maintenance plan.
