What does insufficient tack coat cause?
Tack coat is sticky, which is very important for forming a secure bond between the two layers of asphalt. The lack of tack coat may result in slippage and can cause concentrated stresses leading to total pavement failure.
What is ss 1 tack coat?
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. SS-1 can also be used appropriately where coating, bonding and waterproofing may be required.
When would you use a tack coat?
Tack coat is a sprayed application of an asphalt binder upon an existing asphalt or Portland cement concrete pavement prior to an overlay, or between layers of new asphalt concrete.

What is the difference between seal coat and tack coat?
Is tack coat waterproof?
The tack-coated surface should be free of water and other contaminants when the surfacing is applied. The activation temperature of TACK COAT NO. 2 and as the temperature cools it forms a strong bond between the ELIMINATOR® membrane and the surfacing.
