Creve Coeur Paving has created its very own base design. This
design is called Perma-Base. Perma-Base is the result of years of
researching pavement defects. Most pavement defects are caused by
underlying base issues. A weak or unstable base will compromise the
integrity of asphalt surfaces. Have you ever noticed the amount of
skin patches being installed on commercial surfaces that are less than
3 years old? Asphalt pavement should be able to last at least 5 years
without defect as long as the base rock is designed and installed
properly.
Without divulging major details, Perma-Base is a system of rock base
situated in multiple layers to stabilize moist or plastic soils. Clay
is prevalent in our soils here in the St. Louis area. Western regions
have even more clay. These soils are not suitable for building on.
When clay drys out, it shrinks and causes severe cracking or
expansion. Clay also soaks up water like a sponge and does not let
moisture drain. These two scenarios are the leading causes of pavement
defects. Installing a simple crushed rock base over dirt just doesn't
perform well in these conditions. This type of rock base will yield
under pressure if the soil it is on moves, or is wet. When the base
yields, so will the asphalt. This is how cracks and major holes are
formed.
Perma-Base simply provides a stable barrier between the soil and the
asphalt. Wet soils are allowed to stay wet, as Perma-Base is
permeable. This means water that percolates through the soil is
allowed to migrate beneath the base without causing excessive movement
in the soil. This also means that water will not surface through the
asphalt. Water that surfaces through asphalt will cause severe
deterioration and ice in winter months. In drought conditions
Perma-Base will provide a bridge like base for the asphalt to rest on.
This allows the clay to shrink and crack without disturbing the
pavement above. Basically, all the defects that you see in your
pavement are kept below the barrier of Perma-Base. The defects only
become an expensive problem if they are allowed to surface through the
asphalt pavement.
It’s cost effective. Installing Perma-Base does not cost much more
than conventional base designs. You will save lots of money on reduced
maintenance and repair costs. Your asphalt pavement will also retain
its good looks for more years. A major reduction in cracks is a huge
benefit of Perma-Base. The leading cause of cracks is expansion.
Expansion is kept below the surface of the asphalt. If you don't have
cracks, you don't have to fill them.
Perma-Base allows for heavier load forces. This means you don't
have to increase thickness of asphalt to accommodate large trucks or
other heavy vehicles.
Perma-Base also provides a suitable surface
for construction vehicles to use. Project managers will have one less
thing to worry about. Conventional bases are damaged easily by
concrete or refuse trucks. Now you don't have to wait to install the
base until right before paving takes place.
You'll gain the most return on investment when using Perma-Base.
Less repair and maintenance will put more money into your bottom line
Perma-Base is available on both Commercial and Residential surfaces.
