Slurry surfacings are thin layers of an aggregate and asphalt mixture. To make them stick requires an even wetting of the pavement surface.

Road pavements attract dust and oil.

Poor wetting produces poor adhesion.

Thus the pavement must be swept before It is slurried.

It must also be degreased!

Pavement sweeping is essential.

Other methods such as high pressure washing or compressed air are also often suitable.

Degreasing involves the use of detergent, heat or dig out and patching.

If microsurfacing is to be used for rut filling the rut need not be milled. But high spots should be ground off.



 

COVER SERVICES:

 Services need to be protected.

Slurry is thin so it will not unduly add to the height.

Kraft paper or duct tape is used To cover the manhole and then is removed after the slurry is applied.
 

HANDWORK AND EDGES:

Starting and stopping on roofing felt gives straight edges.

CONCRETE/AIRPORTS:

FAA requires tack coat to be used on airports.

This is to ensure an adhesive bond. In most work this is not required! The slurry should wet the surface out and modern slurry machines have prewet bars.

This water application wets the surface, prevents premature break of the emulsion and ensures a good bond.

When the surface is complete it will lose some stone over the first day or two. This should be less than 1% and the smaller stone used in slurry means it is NOT a windshield hazard. In areas where you need to traffic very quickly consider microsurfacing. Sanding too often will give a good result.
