Micro-Surfacing

Micro-surfacing is one of the fastest growing asphalt maintenance tools utilized across Western Canada. Micro-surfacing is a mixture of polymer modified asphalt emulsion,100% manufactured aggregate, portland cement, water and liquid additives. The mixture is proportioned according to specifications and laboratory mix design. Micro-surfacing is a quick set, quick traffic system that is able to accept traffic after a short period of time. Traffic is usually able to resume as normal within hours of application, but set times may vary depending on weather and conditions specific to each project.

Micro-surfacing is used for rut filling, longitudinal and transverse crack repair (special spread boxes are used), leveling or scratch course and surfacing of all roadways from urban streets to major highways. This product fills minor surface cavities and corrects weathered, pitted and raveling asphalt surfaces while adding excellent skid resistance and extending the roadway’s life cycle.

The 100% manufactured aggregates offer superb physical properties combining durability, wear and an aesthetically pleasing appearance. These aggregates generally come in three distinct groupings: Type 1 (fine), Type 2 (standard) and Type 3 (coarse).

  • Low resurfacing cost per M2
  • No asphalt milling
  • No joint cutting or need to adjust utilities
  • Fills cracks while providing a leveled surface
  • No curb loss reveal
  • Minimal traffic disruption
  • No fly stone or dust
  • Low energy consumption, no blue smoke
  • Reduces ponding, eliminating hydroplaning
  • Increased skid resistance
  • No mechanical compaction
  • 100% recyclable

Type 1 :

A very fine aggregate that generates maximum crack penetration while sealing residential traffic areas.

Type 2 :

The most commonly used aggregate utilized in urban areas, arterial roadways, airports and for “Microfill”. Micro-surfacing systems produce many benefits, not only by improving the physical pavement condition, but also by being a cost effective and financially responsible treatment strategy that preserves past investments in existing asphalt surfaces. Since 2000, West-Can has been a leader in developing the market for urban micro-surfacing.

Type 3 :

A coarse aggregate that is primarily used in “Rut Fill” applications and highway resurfacing. This aggregate provides superior skid resistance and reduces hydroplaning/ wheel rutting in heavy traffic areas. Since 2000, West-Can has placed thousands of kilometers of Type 3 micro-surfacing on various highways between Manitoba and British Columbia.
