The present work was undertaken to establish the possible threshold values for Surface Free Energy (SFE) and Binder Bond Strength (BBS) methods for screening asphalt-aggregate systems to ensure excellent moisture damage resistance. A total of sixteen combinations of asphalt-aggregate systems consisted of warm mix additives (WMA) and recycled asphalt pavement (RAP) and WMA-RAP combinations. In addition, the study evaluates the effects of RAP, WMA, and WMA-RAP on compatibility ratio (CR), bitumen bond strength ratio (BSR), and indirect tensile strength ratio (TSR) for different combinations of aggregate-asphalt system. The results showed that compatibility and bond strength between asphalt binders and aggregates deteriorated with the addition of RAP and WMA additives. Threshold criteria for CR and BSR values were identified as 4.80 and 0.90, respectively, with reasonably good accuracy of 90% for the SFE method and 75% for the BBS method. The threshold values, along with the practical framework established in the present study, would help the highway agencies select the most compatible asphalt-aggregate combinations.

目前的工作是建立表面自由能 (SFE) 和粘合剂粘合强度 (BBS) 方法的可能阈值，用于筛选沥青骨料系统，以确保出色的抗湿损伤性。总共有 16 种沥青-集料系统组合，包括温拌添加剂 (WMA) 和再生沥青路面 (RAP) 和 WMA-RAP 组合。此外，该研究评估了 RAP、WMA 和 WMA-RAP 对骨料-沥青体系不同组合的相容比 (CR)、沥青结合强度比 (BSR) 和间接拉伸强度比 (TSR) 的影响。结果表明，添加 RAP 和 WMA 添加剂后，沥青结合料和骨料之间的相容性和粘结强度会降低。CR 和 BSR 值的阈值标准被确定为 4.80 和 0.90，SFE 方法和 BBS 方法的准确度分别为 90% 和 75%。阈值以及本研究中建立的实际框架将帮助公路机构选择最兼容的沥青-集料组合。
