Microsurfacing is a thin overlay used in the repair and preventative maintenance of roadways.
Micro Surfacing is a surface treatment designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting the structure from further oxidation and raveling, and restoring a uniform black appearance. It is the most economical choice when leveling is required. Micro surfacing boasts quick construction times and minimal disruption to the traveling public.
ADvantages:
- Reduces life-cycle costs by 25 - 45% compared to traditional resurfacing methods.
- Reduces greenhouse gases by 44% or more, and energy use by 54% or more compared to traditional resurfacing methods.
- Reduces raw materials by 35% or more compared to traditional resurfacing methods.
- Return to traffic within 1 hour.
- Adds 6 - 8 years or more when applied for optimum preservation performance.
Issues Addressed
- Loss of friction
Oxidation - Uneven surface profile
- Raveling
- Rutting
- Lack of uniform color for
restriping
Attributes
- Increases skid resistance
- Improves color contrast between pavement and striping
- Restores surface characteristics
- Protects the structure from moisture intrusion
- Protects the structure from oxidation
- Maintains drainage patterns and curb reveal
- Restores road profile (within limitations)
- Resistant to rutting and shoving
Common Combinations
- Crack seal + micro surfacing
- Rut filling with micro surfacing + surface course of micro surfacing
- Leveling/scratch course of micro surfacing + surface course of micro surfacing
- Cape Seal: (Chip seal + Micro surfacing)
- Scrub Cape Seal (Scrub seal + Micro surfacing)

Applications
Western Asphalt Products have a variety of applications
Seal Coats are treatments that provide effective pavement maintenance to all structurally sound roadways.
CA-90 is a specially formulated cold pour rubberized crack filler.
Microsurfacing is a thin cold-mix overlay used in the repair and preventative maintenance of roadways.
Cold In Place (CIP) Recycling was a new technology introduced in the early 1990’s in Ontario.
Fog sealing is generally a light application of spray applied slow set emulsion.
Tack Coat is a spray applied emulsion which provides a thin adhesive film of asphalt between existing road pavement and a new surfacing layer.
Dense-graded cold mixed asphalt can be an economical alternative to traditionally hot mixed asphalt, especially in areas where there is a long distance to the nearest hot mix plant.
Specialized Cutback Asphalt and Asphalt Emulsions can be used to create a concrete foundation water proofing.
Applying driveway sealer to an asphalt driveway will improve both aesthetics and lifespan of your asphalt driveway.
