- Understanding types of Tack Coat Material
Introduction Today, the application of tack coat in the asphalt and pavement industry is increasing The most important component of asphalt pavement is the bondage between asphalt pavement and layers Tack coat is a sprayed application of an asphalt binder upon an existing asphalt or between layers of new asphalt concrete The
- Prime Coat vs Tack Coat: Key Differences When to Use Each
Prime Coat vs Tack Coat: prime coat is a penetrating bituminous treatment applied on untreated granular base to bind dust and stiffen the surface before paving; tack coat is a thin bonding layer applied between asphalt (or concrete) layers to prevent slippage and delamination
- Techbrief: Tack Coat Best Practices - FHWA West Virginia Division
Materials used for tack coats are emulsified asphalt (most common) and performance grade asphalt While cutbacks are still used, their usage is much less than other options, and will not be addressed in this TechBrief

- Materials for Asphalt Tack Coat - Pavement Preservation
The tack coat is used to ensure a good bond between the existing asphalt or concrete pavement, between the layers of a structural pavement and at any vertical surfaces that the new layer will be placed adjacent to, such as curbs, gutters, utilities, and construction joints
- Best Practices For Tack Coat And Achieving Bond Strength
Undiluted Emulsion - an emulsion which consists primarily of a paving grade asphalt binder, water, and an emulsifying agent Diluted Emulsion - an emulsion with additional water added to it The most common dilution rate is 1:1 (one-part undiluted emulsion and one-part additional water)
