PressurePave® is a system that combines a custom-made crack seal formula, injected by a matrix of pressurized boxes, with a thin and highly durable asphalt overlay.
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.
PressurePave® allows agencies to treat streets that would fall in the mill and overlay category while spending significantly less. By supplementing PressurePave into a street program, agencies can effectively treat twice as many streets with the same budget while adding a durable surface layer with a history of 12-15 year surface life.
Can PressurePave® be used in place of the common mill
and asphalt overlay process?
The short answer is Yes!
There will always be a need for the mill and asphalt overlay in
street programs. Mill and overlay is excellent at building structure
and correcting imperfections in the overall rideability of the road,
but it does have some downsides.
Two great examples of PressurePave® replacing mill and overlay are Lincoln, NE and Irving, TX. In both cases they experienced a significant cost savings, which resulted in more dollars spent on reconstruction. BUT can PressurePave® hold up over time when applied on streets in poor condition? The answer is yes, and we have the historical data to prove it. In the video above, it shows just some of the results we have seen from PressurePave over time.
Although microsurfacing and PressurePave are used in vastly different applications within a pavement maintenance program, there are some cosmetic similarities. Due to these similarities, it is important to understand what you, as a city or county, are purchasing and how they perform.
Cul-de-sacs take an astonishing amount of abuse from the twisting/turning of trash trucks and other vehicles. Unique problems demand unique solutions which is why we developed and patented “The Cul-de-sac Truck.”
Understanding the unique stresses placed on Cul-de-sacs, Donelson Construction has taken a proactive approach to extend the lifespan of cul-de-sacs. Michael Donelson introduces their patented technology: a specially designed truck that applies a durable material to the road surface, tailored to withstand the rigors of twisting and turning traffic.
Specs are great but what about historical data?
City, county, and state agencies lean heavily on specs, relying on
them to indicate a process or product's performance. In many cases,
following DOT specs does not guarantee success. Especially when
utilizing multiple rock, oil, and chemistry suppliers (whoever is
closest to the project). A contractor is essentially HOPING all the
product's components will work perfectly together. Without
historical data with those specific components, utilizing the
untested combination can be a gamble.
30 Minute Application = 15 Years Surface Life
I think most municipalities would agree, if a construction process
provides good results but receives negative feedback from the
general public, that process will likely not be in their program for
long. Negative feedback is the bane of any contractor but one of the
easiest ways to get on someone's bad side is to keep them from where
they need to go. Therefore, the most popular contractors or pavement
preservation methods are the ones with the fastest return to
traffic.
If you are one of the lucky few, your paving budget has increased to
meet rising asphalt prices. Most cities and counties are not so
lucky. What if you could maintain the same budget yet pave twice as
many streets?
Option #1 You mill and asphalt overlay 10 miles and treat the
streets in poor condition (PCI scores 30 - 60)
Option #2 You PressurePave 20 miles and treat streets in poor to
moderate condition (PCI scores 40 and above).
Cracking is the first step on a downward spiral of a pavement's
life. Why? Because cracking introduces water, oxygen, and overall
exposure to the base underneath. Many believe the solution is to
shave off 1 to 2 inches of asphalt and hope that erases the cracking
issue. Not only is that expensive, but what if it doesn't work? What
if there are still cracks under the new surface you just applied?
Applying any surface over an existing crack will ultimately lead to
reflective cracking. This is when an existing crack reappears on the
new surface applied over it. Depending on how thick the new surface
is will determine how long until the crack will reappear.
Typically, 1 inch per year.
For example, a 1 inch asphalt overlay will show a reflective crack
within 1 year, a 2 inch asphalt will show a reflective crack within
2 years.
