Abstract This study aims to investigate the effect of using Nano Hydrated Lime (NHL) as asphalt binder modifier on the moisture sensitivity of Hot Mix Asphalt (HMA) with consideration of its impact mechanism on bituminous-aggregate adhesion. In order to investigate the moisture susceptibility, the indirect tensile strength (ITS) test and the concepts of surface free energy (SFE) have been applied. To simulate environmental conditions, samples of HMA have been exposed to 1, 3 and 5 freeze-thaw cycles. The results show that the use of NHL increases the ITS values and the indirect tensile strength ratio (TSR) in both types of aggregates.

纳米熟石灰改性沥青结合料对沥青混合料湿敏性热力学概念的影响

摘要 本研究旨在研究使用纳米水合石灰（NHL）作为沥青粘合剂改性剂对热拌沥青（HMA）湿敏性的影响，并考虑其对沥青-集料附着力的影响机制。为了研究湿气敏感性，已经应用了间接拉伸强度 (ITS) 测试和表面自由能 (SFE) 的概念。为了模拟环境条件，HMA 样品已暴露于 1、3 和 5 次冻融循环。结果表明，NHL 的使用增加了两种类型集料的 ITS 值和间接拉伸强度比 (TSR)。
