Macro-Surfacing

What is Macro®-Surfacing?
First applied in 1988,  Macro®-Surfacing is a specialized open-graded cold mixed asphalt. It consists of a single-graded aggregate, a polymer modified binder, fines and other additives. It is a hard wearing surfacing for pavement preservation and rehabilitation. It is similar to slurry surfacing in it's application but is specialized for situations where noise reduction, drainage  and reduced crack reflectivity are desired.
What is it used for?
Macro®-Surfacing  can be used for pavement patching, surface profiling, and restoring texture to some binder flushed pavements. It can be rolled with either pneumatic or steel drum rollers after the "break" of the emulsion and is designed with a high softening point binder emulsion for heavy traffic loadings.

Are there different types?

Macro®-Surfacing are all polymer modified Cationic quick-traffic, quick-cure. They use emulsions designated as CQT-QC . Different stone sizes give different surface textures. 1/8 by 10 Type A gradation is used for parking lots and minor roadways. 1/4 by 6 Type B is a general purpose  gradation used for residential streets. 3/8 by 4 Type C is used for applications such as arterial roads, highways and freeways. Other special mixes, such as coarser gradations and gap-grades are also available for pavement repair and re-profiling.

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.



Macro®-Surfacingis polymer modified for longer wear and better resistance to traffic and cracking. Crumb Rubber modification within the asphalt binder prior to emulsification and also post addition can be used to impart special properties for severe application conditions and crack retardation.We at VSS are experts in binders.


How Is Macro®-Surfacing made?

Macro®-Surfacing 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?

Macro®-Surfacing extends pavement life by protecting and preserving it from oxidation and wear. This results in a pavement that is quieter, better to drive on, look at and will require less maintenance in the future thereby costing less in the long run.


What does it cost?
Generally Macro®-Surfacing is laid thicker than slurry seal (2 stones compared to one) so is 40-60% more expensive. A VSS estimator will be pleased to measure your job and give you an exact price.
