Abstract: Surface free energy (SFE) technique is used to mechanistically quantify the moisture-induced damage potential of asphalt mixes. A SFE database was developed for commonly used asphalt binders and aggregates in Oklahoma, as a part of the ‘SPTC15.2-19’ project. The aim of the workshop is to discuss this SFE database and demonstrate how moisture-induced damage potential of asphalt mixes can be evaluated mechanistically using this database. Also, a comparison of the SFE technique with other conventional and unconventional test methods used for evaluation of the moisture-induced damage potential will be discussed in this workshop.
