An asphalt emulsion is a combination of asphalt binder (asphalt cement), water, and a very small amount of emulsifying agent (normally less than 1 percent). Typical asphalt emulsions consist of 55 to 70 percent asphalt binder, depending on the grade of the emulsion. Most grades of asphalt emulsion used for tack coat …
Tack coat (also known as bond coat) is a light application of asphalt emulsion between hot mix asphalt layers designed to create a strong adhesive bond without slippage. Heavier applications may be used under porous layers or around patches where it also functions as a seal coat.
Tack Coat. Tack coat (also known as bond coat) is light spray application of diluted asphalt emulsion between hot mix asphalt layers designed to create a strong adhesive bond without slippage. Heavier applications may be used under porous layers or around patches where it also functions as a seal coat.
TACK COATS & FOG SEALS USING ASPHALT EMULSIONS 11.1 Scope This performance guide covers the use of asphalt emulsion for bot h tack coat and fog seal applications. It should be used as a gui de in achieving succe ssful results through proper construction practices and adequate knowledge and understanding of asphalt emulsions. 11.2 Definitions
Tack Coat (Asphalt Emulsion Type SS-1/SS-1H) DESCRIPTION: GemSeal® Tack Coat is an anionic slow setting asphalt emulsion which serves as a tack coat for better coating adhesion on asphalt pavement surfaces. USES: GemSeal® Tack Coat asphalt emulsion is used as a general-purpose tack emulsion and bonding agent between new bituminous asphalt and ...
Dalton SS-1H asphalt binder is an anionic emulsion designed for use as a tack coat for patching, paving, overlays and coating blacktop. SS-1H promotes adhesion to blacktop (bituminous concrete). It can be applied via spray, brush or squeegee and …
Dilution. Sometimes emulsified asphalt tack coats are diluted with water to increase the total volume of liquid while maintaining the same volume of asphalt binder within the emulsion. This can help achieve a more uniform application without applying excessive amounts of asphalt binder. Dilution should be avoided if possible due to the various problems that can result from improper dilution (e ...
Rapid setting emulsions were added to Table 702-9 Tack Coat, so they can be used for hot mix asphalt (HMA). The asphalt residue for tack coat application was increased to a minimum of 38% from
Tack coats are a vital component of an asphalt pavement's structural system as they bond the multiple asphalt lifts into one monolithic layer. Poor tack coat application results in poor bonding of the asphalt layers. The usual pavement distresses associated with poor or no tack coat is slippage cracks (typically at locations where traffic is …

•Tack Coat—sprayed application of liquid asphalt upon an existing asphalt or Portland cement concrete pavement which may or may not have been milled before an overlay, or between layers of fresh asphalt concrete. •Original Emulsion (emulsified asphalt)—an undiluted emulsion which consists of a …
Anionic and cationic AASHTO certified emulsions are used for a variety of asphalt construction applications, including paving tack coats, surface treatments, cold mixes and other specialty applications. At All States Materials Group, we have more than 35 years of experience formulating, manufacturing and using emulsified asphalt in construction.
an emulsion. The asphalt binder tack coat used to bond the geosynthetic pavement interlayer is sufficient to provide the bond for the layer of hot mix asphalt that will placed over the geosynthetic pavement interlayer. Tack Coat Guidelines Division of Construction April 2009 Page 2
Terminology •Tack Coat: sprayed application of liquid asphalt on existing asphalt or Portland cement concrete pavement which may or may not have been milled before an overlay or between layers of fresh asphalt concrete. •Emulsion: (emulsified asphalt)- an undiluted emulsion which consists of a mixture of paving grade binder, water, and emulsifying agent.
