Emulsified Asphalt SS-1 Tack Coat Walker Emulsions
Contact Us. SS-1 is an anionic slow setting asphalt emulsion primarily used as a tack coat typically providing that "glue" to bond an existing base pavement layer to a newly applied layer. Ensuring emulsion sets before new layer is placed facilitates good bonding to prevent slippage which is crucial for the structural performance of the final

Tack Coat And Prime Coat Applications With Asphalt
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 Information Asphalt Institute
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

Prime coat and tack coat. Prime coat is used as an initial sealant in the process of laying asphalt, providing stronger adhesion between layers. It is used for the protection of substrate, defending against moisture and debris. Tack coat creates an adhesive bond between layers of asphalt, and can be used to protect against moisture and bacteria.
