Seal Coating
Asphalt seal coating is a broad term used to describe several types of asphalt-aggregate applications, usually less than 25mm thick and applied to any kind of road surface. The road surface may be primed, granular base, or an existing asphalt or Portland cement concrete pavement. The treatments can be placed in one or more lifts in combinations of types. Available raw materials, cost and treatment life cycle will have a large impact on the process chosen.

Features & Benefits:
- Emulsions can be used with damp aggregate, which is actually preferred
- Environmentally friendly process, do not need elevated temperatures
- Emulsions are low emissions eliminating fire hazards and air quality problems associated with cutbacks
- Custom formulas for existing environmental conditions and available aggregates
- Polymer modified emulsions can be used to enhance asphalt properties for; durability, stability impermeability, early stone retention and reduces flushing and bleeding
- Renews weathered pavements
- Improves skid resistance, available in various textures
- Fine aggregate treatments can improve street sweeping
- Reduces ravelling
- Restores a uniform cover
- Prevent the intrusion of moisture and air
- Seals very small cracks and surface voids
- Enriches and coats weathered aggregate particles at the surface
- Delineate shoulders from traffic lanes
