Asphalt seal coating is a broad term used to describe several types of asphalt-aggregate applications, usually less than 25 mm thick and applied to any kind of road surface. The road surface may be primed, granular base, existing asphalt or a portland cement concrete pavement.
Seals can be placed as a single lift or in multiple lifts depending on the traffic demands and the conditions of the existing surface.
Features and Benefits
- Emulsions can be used with damp aggregate, which is actually preferred.
- The process does not require elevated temperatures, making it environmentally friendly.
- Emulsion usage significantly reduces VOC emissions, which are typically associated with the use of cutback asphalts.
- Custom formulas can be created for existing environmental conditions and using available aggregates.
- Polymer-modified emulsions can be used to enhance asphalt properties for durability, stability, impermeability and early stone retention, as well as to reduce flushing and bleeding.
- Renews weathered pavements.
- Improves skid resistance; available in various textures.
- Fine aggregate treatments can improve street sweeping.
- Reduces ravelling and restores a uniform cover.
- Prevents the intrusion of moisture and air.
- Seals very small cracks and surface voids.
- Enriches and coats weathered aggregate particles at the surface.
- Delineates shoulders from traffic lanes.
