Despite the environmental and economic benefits of using glasphalt, it suffers from a number of disadvantages. The most common damage in glasphalt is the effect of water on bitumen-aggregate adhesion and the occurrence of moisture damage. One way to improve the resistance of glasphalt against the moisture damage is to use anti-stripping additives. Accordingly, the effect of two types of nanomaterials including nano hydrated lime (NHL) and nano calcium carbonate (NCC) as bitumen modifiers on the moisture sensitivity of glass asphalt has been investigated in this study. The moisture sensitivity of asphalt mixtures was assessed by the AASHTO T283 test and surface free energy (SFE) method. Indirect tensile strength (ITS) results show that the use of waste glass cullet increases and decreases the resistance of asphalt mixture in dry and wet conditions, respectively. An increase in the number of freeze–thaw cycles causes a decrease in the ITS of the glasphalt. The obtained results showed that using both nanomaterials in glasphalt significantly improved the resistance to moisture sensitivity. Bitumen modification using NHL and NCC, which was added in 2% bitumen, reduced the SFE of cohesion, which resulted in improving the bitumen coating on the aggregate surface and the adhesive between bitumen and aggregate.

尽管使用石蜡油具有环境和经济效益，但它仍具有许多缺点。glasphalt中最常见的损坏是水对沥青集料附着力的影响和水分损坏的发生。改善玻璃纤维抵抗潮湿损害的一种方法是使用抗剥离添加剂。因此，本研究研究了两种类型的纳米材料，包括作为沥青改性剂的纳米级熟石灰（NHL）和纳米碳酸钙（NCC）对玻璃沥青的湿敏性的影响。沥青混合料的湿度敏感性通过AASHTO T283测试和表面自由能（SFE）方法进行了评估。间接抗张强度（ITS）结果表明，使用碎玻璃碎玻璃会增加和降低干湿条件下沥青混合料的抵抗力，分别。冻融循环次数的增加会导致玻璃胶的ITS降低。获得的结果表明，将两种纳米材料都用于玻璃石蜡中可显着提高对湿气敏感性的抵抗力。使用NHL和NCC进行的沥青改性（在2％的沥青中添加）降低了内聚力的SFE，从而改善了骨料表面上的沥青涂层以及沥青和骨料之间的胶粘剂。
