Evaluation of Bond Performance of FastTack® Emulsion for Tack Coat Applications

The purpose of this study was to evaluate the bond performance of FastTack® relative to that of AET through a host of laboratory tests. FastTack® is a proprietary, rapid-setting emulsion used as a bituminous tack coat for pavement applications. The product, produced by Whitaker Roads Corporation, is touted to exhibit a very fast set time feature that distinguishes it from regular rapid-setting emulsions. This is achieved by the introduction of certain additives, a process referred to as Colnet®. The rapid set time is beneficial for fast-track paving projects and hence could prove to be highly cost effective. However, the adoption of FastTack® as an approved replacement to typical tack coats used by PennDOT is contingent on it exhibiting bond characteristics similar to those exhibited by other rapid-setting emulsions such as AET.
