Bond/Tack Coats and Primers

Eliminates slippage planes and provides a better bond between new and existing pavement layers.

A single application of either a specially formulated asphalt emulsion or a low-viscosity asphalt cutback is a very inexpensive standard requirement used to improve the bond between layers of pavement.  Proper bonding is essential to achieving a monolithic pavement/structure for optimal strength as per the design criteria. There are many different types of tack coats and emulsions.

A bond coat is a spray application of asphalt emulsion. It is applied to an existing asphalt or Portland cement concrete surface prior to a new asphalt overlay or patching. This eliminates slippage planes and provides a better bond between new and existing pavement layers.

Primers

A prime coat is a single application of either a specially formulated asphalt emulsion or a low-viscosity asphalt cutback. Its primary functions are to penetrate quickly into the granular surface, bind the material together, partially waterproof the granular surface to prevent water erosion, provide a temporary riding surface prior to overlay or seal coating, and provide a bond between the existing surface and the new wearing surface.

The asphalt emulsions used as prime coats typically contain a combination of asphalt and specially engineered agents that aid in penetrating the granular surface while binding the aggregate particles to achieve stabilization.
