Preserve,
maintain and protect.....PDC gives extended life to parking lots,
driveways, playgrounds, and streets. Also can be used on bituminous curbs.
PDC is the ideal preservative to protect asphalt
from damage and aging.
Surface treatment of any type is more critical today than
ever before as more products, primarily plastics, are made from petroleum residues.
The modern refinery cracking processes used to synthesize these plastics has depleted
liquid asphalt of many of its vital properties.
Due to this change in chemical composition while processing
asphalt today, the life expectancy of pavement surfaces has been decreased overall by one
third to those laid 10 years ago. Therefore, rejuvenation therapy is now a necessity
to extend the lifetime of asphalt pavements and replace oils which no longer remain at the
time of installation.
| The above graph illustrates the need for
routine maintenance to avoid accelerated surface degeneration after the first six years of use. Every year that surface maintenance is withheld increases the cost of major repair. |
Maintenance costs
will drop dramatically.
When PDC is used as a regular preventive maintenance procedure, you will
significantly extend the life of your asphalt surface.
PDC will revitalize asphalt surfaces so that the slurry seals, overlays
and other more expensive resurfacing measures can be avoided. Long-term, the cost of
maintaining parking lots and roadways will be drastically reduced.
One
application of PDC protects and restores your asphalt surface.
Oil
treatments, oil seals, and coal tar seals all have one flaw in common. They merely
coat the top surface of the asphalt to which they are applied. They make the surface
look better, but they quickly wear off and leave the surface unprotected.
PDC is dramatically different. It actually penetrates the asphalt.
PDC is a coal tar base, cold-applied product
designed to protect and restore the plasticity, retard the aging, lower the viscosity and
prevent loss in durability of a bituminous pavement.
PDC protects and preserves a bituminous pavement
by a double action process. Part of the
PDC penetrates
into the asphalt. While it is rejuvenating, the other portion remains on the surface
protecting the pavement from water, salt, gasoline, oil and leaves the cosmetic blacking
agent to beautify.
PDC Application Specifications
uses:
Pavement
Dressing Conditioner is recommended for treating asphaltic concrete highways, city and
suburban streets, parking lots, driveways, parking aprons and
bituminous curbs.
Condition
of the pavement surface:
The pavement
scheduled for treatment should be weathered, except in those instances where the pavement
is deficient in binder, or the mix was produced and laid too hot and the asphalt cement
has prematurely weathered.
Preparation
of the pavement surface:
Immediately
prior to the application of Pavement Dressing Conditioner, all debris, dirt, mud or other
foreign matter that might prevent rapid penetration of the Pavement Dressing Conditioner
into the pavement, or that might absorb excessive quantities of it shall be removed from
the pavement surface.
Application
of Pavement Dressing Conditioner:
Pavement
Dressing Conditioner shall be applied through a pressure distributor at a temperature of
60º F to 120º F. Application rates may vary depending upon condition of the
pavement. Rate is to be determined by pre-test applications made by the contractor.
Application
equipment:
Pavement
Dressing Conditioner shall be applied by a full circulating spray bar, equipped with
proper nozzles and a distributor system, encompassing a positive displacement pump capable
of pumping low viscosity material. The system is to provide sufficient pressure to
deliver the specified rate of application.
Weather
Limitations:
Pavement
Dressing Conditioner shall be applied only to dry pavement, when the prevailing daytime
pavement surface temperature is 50º F or above and there is no forecast of rain for at
least eight hours after application. Approximate drying time is 24 hrs.
