The patented PressurePave® system is one of the most versatile tools in the pavement preservation industry. Able to preserve pavements many would consider to be candidates for mill and overlay, this hybrid system pressure-injects a crack sealant into pavement while simultaneously applying a durable thin asphalt overlay.
This system is more efficient and cost effective than many other
pavement preservation options. With a price that can be
significantly less than the cost of a mill and asphalt overlay, and
a 15-year average surface life, the life cycle cost is ideal for
public and private agencies wishing to cut costs or double the
amount of roadways they are able to treat.
Whether it is a residential street or busy arterial, the time it
takes to repair/resurface and return roadways back to normal traffic
flow is extremely important to the public. With
PressurePave®, one simple application accomplishes
what would historically require multiple products, processes and
traffic disruptions. The chemical reactions within the
PressurePave® materials enables a resurfaced pavement
to be ready for initial traffic flow usually within 30 minutes.
Many times, when surface treatments are applied over cracked streets
the cracks reappear within the first one to two years. This cracking
can be slowed but never stopped even with the application of the
MAQS® surface. But if the
PressurePave®'s more ductile and crack resistant
sealant is present the base pavement will remain sealed.
Specifically engineered to fill small “hairline” and large
transverse/longitudinal cracks while traveling at 6 feet per second,
the pressure-injection system is capable of coating the entire
surface with a ductile and highly water-resistant membrane. This
membrane is chemically engineered to remain ductile in cold
temperatures and tough in the heat. If this membrane were to crack,
it is designed to be able to self-heal with the application of heat
and pressure (traffic).
(Cut-out reveals crack resistant under seal.)
PressurePave® is designed to treat pavements that are normally not suitable for conventional pavement preservation methods such as hot rubber crack seal, slurry, microsurfacing, and seal coat.
This system allows agencies to extend the life of pavements in poor
condition without having to pay for a full mill and overlay.
In technical terms, pavement preservation products are generally
designed to treat surfaces with a Pavement Condition Index (PCI) of
80 and above. PressurePave changes that, allowing agencies to
preserve pavements as low as 40 (assuming no subgrade issues).
