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.
