CONTRACTING: MICROSURFACING |
What is Microsurfacing? |
Microsurfacing
is a cold mixed asphalt. It consists of a graded aggregate, a binder
, fines and additives. It is a hard wearing surfacing for pavement
preservation and rehabilitation. It is a sort of slurry surfacing
but is specialized for situations where very quick trafficking, rut
filling or extreme conditions of heat or cold are likely.
|
What is it used for? |
Microsurfacing
is for the more specialized slurry jobs of rut filling, restoring
surface profile, heavy traffic or where very quick trafficking is
essential. Like night work or freeways. |
Are there different types? |
Microsurfacings
are all polymer modified. Different stone sizes give different surface
textures. parking lots and runways. Type II is general purpose it
is used for all applications including arterial roads and highways.
Type III is the coarsest and is used on freeways, rut filling and
high speed roads. Special mixes are used for rut filling and some
applications for very rapid traffic.
Different types of aggregate will give lighter or darker results.
The famous Table Mountain black rock will give your surfacing that
new look all through its life.
Microsurfacings may be polymer modified for longer wear and better
resistance to traffic and cracking. This modification includes latex
rubber, crumb rubber and other polymers. VSS are experts in binders.

How Is Microsurfacing Made? |
Slurry
is mixed in a traveling paver truck. The exact proportions, determined
in a laboratory mix design, are mixed in a pugmill controlled by the
advanced electronics and hydraulics of the VSS Macropaver- the machine
we design and build ourselves.
It is laid through a specially designed spreader box. It is fast and
efficient as well as cost effective. This makes a smooth but textured
surface. |
What does it do? |
Microsurfacing
protects and preserves, extending pavement life. This results in a
pavement that is better to drive on, look at and will cost less in
the long run.
|
What does it cost? |
| Generally microsurfacing is laid thicker than slurry seal (2 stones
compared to one) so is 30-50% more expensive. A VSS estimator will
be pleased to measure your job and give you an exact price. |
