What is Micro Surfacing?

Micro surfacing is a surface treatment consisting of manufactured aggregate, portland cement, and polymer-modified asphalt emulsion. Micro surfacing is versatile and may be used for increasing skid resistance, color contrast, rut filling up to 5Omm wheel ruts, longitudinal and transverse crack repair, leveling for proper surface drainage, segregation, raveling, flushing, oxidized surfaces and filling small potholes.

Micro surfacing is versatile and can be used on various types of roads. For example, it is used on main highways such as Hwy 2 in Alberta where traffic can reach over 20,000 + annual average daily traffic (AADT) counts. It is used on secondary roads with less than 100 AADT.

It is also used annually in residentiaI areas with less than 50 AADT, industrial areas, and on arterial roads in the largest cities in Western Canada. A micro surfaced road can last 7 – 10+ years.

Micro surfacing has successfully been used on the Hwy 1 Trans Canada in Manitoba for over 10 years and is still performing well. The arlier micro surfacing is applied on the life-cycle curve of a roadway, the higher quality the roadway will remain.

Micro surfacing is proven to improve roadway safety, lower greenhouse gas emissions and be more economical than waiting until rehabilitation is required (e.g. 50mm mill and inlay).

Micro surfacing is a mixture of polymerized bitumen emulsion, specially graded fine aggregates, cement, water and additives, mixed homogeneously on site in a special purpose built Micro surfacing machine.

It is an environment friendly cold mix application treatment applied over an existing pavement surface which is structurally sound, but  the surface shows signs of premature ageing, oxidised, aggregate loss / ravelling, cracking, high degree of polishing etc. Micro surfacing helps in preservation of pavement strength and can be used both for preventive and periodic renewal treatment. Micro surfacing product is a globally renowned and established product in this segment.
