SLURRY/MICRO SYSTEMS – McAsphalt

SLURRY/MICRO SYSTEMS

SLURRY/MICRO SYSTEMS

Cost-effective micro-surfacing, roadway restoration and improved skid resistance.

McAsphalt’s slurry systems fill many specific needs, such as cost-effective micro-surfacing, roadway restoration and improved skid resistance. They can also provide an infinite variety of coloured surfaces for safety or decoration.

Features and Benefits

  • High production rates mean lower user costs.
  • Eco-efficient processes save energy and resources compared to hot mix overlays.
  • Slurry systems can be used as a cost-effective alternative to micro-surfacing in areas that do not require cross-sectional profile correction or rut fill.
  • Prevents surface distresses, keeping good roads in good shape.
  • Restores a roadway surface without affecting curb reveals.
  • Reduces water and air infiltration, which minimizes oxidation, raveling and freeze/thaw damage.
  • Improves skid resistance; gradation can be varied to achieve the desired level of friction.
  • Provides a protective layer/wearing course, which extends the service life of the roadway.
  • Covers segregated areas: end of load, random, longitudinal, gearbox segregation, etc.
  • Covers flushed and bleeding areas.
  • Multi-lift system enhances the drivability of the roadway.
  • Enhances aesthetics of the existing roadway by covering defects and imperfections.
  • Economical solution to preserving infrastructure and capital investment in pavements.


Slurry Seals

Slurry seal is a mixture of aggregate, emulsified asphalt, water and additives that are properly proportioned, mixed and spread over a prepared surface. A polymer-modified system can be used in the same application and will enhance one or more properties of the slurry to better meet a particular project requirement.

Micro-Surfacing

Micro-surfacing is composed of engineered, polymer-modified asphalt emulsions mixed with crushed well-graded aggregate, mineral filler, water and additives. The main difference between this system and slurry systems is that micro-surfacing is stackable and therefore engineered for rut fill applications and minor structural deficiencies.

Cape Seals

A cape seal is a combination of a single-chip seal application followed by slurry seal or micro-surfacing. The slurry or micro-surfacing application helps fill the voids between the chips.

Coloured Slurry

Coloured slurry is a mixture of synthetic emulsion binder, pigments and specially selected aggregates. Uses include lane delineation, shoulder delineation, decorative medians, crosswalks, driveways, golf cart paths, bike paths and turn lanes.
