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. Microsurfacing 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 very 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 in all traffic conditions from urban streets to major highways. Microsurfacing my be applied to most structurally sound pavement surfaces with out the need for a tack coat or rolling.

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

Type 1 (#200*1/8): A very fine aggregate that generates maximum crack penetration while sealing residential traffic areas.

Type 2 (#200*1/4): The most commonly used aggregate for Micro Surfacing, utilized in urban areas, arterial roadways and highways. This product fills minor surface cavities and corrects weathered, pitted and raveling asphalts.

Type 3 (#200*3/8): 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.

Micro surfacing is an economical alternative to road maintenance practices for municipalities and its’ ratepayers.
