Periodically, when the Kentucky Transportation Cabinet’s (KYTC) the Division of Construction receives requests to use non-standard warm mix asphalt technologies, it may be asked to waive the temperature specification or other product specifications/processes. The short-term and long-term impacts of this waiver are not completely understood. The Division of Construction approves these requests and notes their use, however, no follow-up studies have been done to evaluate the performance of non-standard warm mix asphalt. Similarly, no previous studies have compared data on quality assurance/quality control (QA/QC) and performance for these mixtures with those of standard warm mix asphalt mixtures. Thus, the performance of non-standard warm mix asphalt projects has not been thoroughly evaluated.
