Provided herein is a tack coat for use with paving applications and a method of making the same. The tack coat is substantially non-tracking, and includes asphalt, a pH adjustor, an emulsifier, acrylic, and water. In certain embodiments, the tack coat may also include a stabilizer to prevent settling of the emulsion during storage. The method of producing the tack coat involves heating the asphalt in one tank, and heating the water and emulsifier in a second, separate tank. This mixture of the water and emulsifier is referred to as soap, and is then mixed with asphalt, and the acrylic may be added to the mixture immediately thereafter, with a stabilizer, or later, just prior to shipment of the product, in which case a stabilizer may not be required. The tack coat exhibits moderate softness, with a penetration value above 40 dmm. |
