Pavement
Performance Histograph
As
shown below, slurry seal maintenance dramatically extends
pavement life. Although the serviceability of an untreated
asphalt pavement is still adequate after several years of
use, pavement deterioration has already begun.
A
slurry seal maintenance program undertaken before significant
pavement deterioration has begun is essential to proper pavement
maintenance.
Preventive
maintenance is more cost-effective than corrective maintenance.

Advantages
of Using Slurry
As
the most versatile of any pavement surface treatment system,
slurry seal is also unique in its ability to deposit a durable
bituminous mixture in accordance with the demands of a variably
textured surface - filling cracks and voids, sealing weather-tight,
and providing color and texture delineation in a single pass.
- Low
cost
- Economical
to install, highly cost-effective to use.
- Rapid
usability
- Easy,
swift application of a new overlay makes slurry especially
attractive for rehabilitating busy thoroughfares, parking
lots, and airport runways. The new surface is ready for
use just hours after application.
- Preventing
problems
- Used
over newly laid pavements, slurry seal will prevent surface
distresses such as the effects of weathering from occurring.
Oxidation, loss of oils, loss of matrix, and embrittlement
of the mix are minimized. It also provides special durability
and texture not available in the underlying mix.
- Correcting
problems
- Existing
distresses in older pavements surface cracking,
ravelling, loss of matrix, increased water and air permeability,
and slipperiness due to flushing and aggregate polishing
can be corrected through a slurry application.
Waterproofing is also achieved, preventing further deterioration.
An all-weather, long-lasting surface is created that offers
skid resistance and improved handling characteristics
for drivers.
- Aesthetic
value
- With
one simple application, existing pavement receives a new
wearing surface of uniform black color and texture. Enhanced
appearance means increased property value, marketing potential,
and buyer acceptance. Thoroughfares, shopping center parking
lots, and other public or commercial pavements treated
with slurry seal become more attractive and eye-appealing.
Benefits
of Pavement Maintenance
Even
the best of surfaces are subject to the wear and tear caused
by time, weather, and traffic. No surface is permanent.
By
undertaking a program of planned pavement maintenance, considerable
savings in rehabilitation costs may be achieved. Your pavement
surface will remain sound, usable, and safe. Extensive downtime
needed to repair deep cracks and potholes will be reduced
or eliminated.
The
application of slurry seal will significantly extend the life
of existing pavements by protecting the under-surface from
damage caused by water seepage. Improved surface performance
is an added bonus.
A
pavement maintenance program using slurry seal will not only
help to protect your pavement, it will help to protect your
paving investment.
