One of the most frequently applied materials in cold weather is deicer, which is utilized to maintain winter roads. The effect of various deicers on moisture sensitivity has been explored by researchers in the asphalt industry; however, their effect on thermodynamic parameters and fatigue behavior of asphalt has rarely been studied. In this study, the effect of NaCl, potassium acetate, and calcium magnesium acetate deicers on fatigue and moisture performances of asphalt was explored using nano hydrated lime. Two prediction models of fatigue life ratio (NfR) and tensile strength ratio (TSR) were presented using genetic programming and group method of data handling to obtain optimal nano hydrated lime content. Finally, according to the results of deicer-forming minerals, two new optimal deicers were obtained, and their effect on TSR and NfR was compared with the three above-mentioned deicers. Results showed that TSR and NfR of calcium magnesium acetate saturated samples were higher than those of NaCl and potassium acetate saturated samples. Moreover, by modifying the properties of bitumen with nano hydrated lime, adhesion free energy, cohesion free energy, and debonding energy amounts increased, which indicates an increase in locking between aggregates and bitumen. By determining the minerals that make up deicers using the energy-dispersive X-ray test, two new deicer compounds were made that had better performance over NaCl and potassium acetate. By optimizing additive percentage in genetic programming method (due to higher accuracy), 1.05% nano hydrated lime was proposed as the best optimal amount for the new optimal deicer to simultaneously increase TSR and NfR.

除冰剂是寒冷天气中最常用的材料之一，可用于维护冬季道路。沥青行业的研究人员已经探索了各种除冰剂对水分敏感性的影响。然而，很少研究它们对沥青的热力学参数和疲劳性能的影响。在这项研究中，使用纳米熟石灰探索了NaCl，乙酸钾和乙酸钙镁除冰剂对沥青疲劳和湿润性能的影响。利用遗传规划和数据处理的分组方法，提出了两种疲劳寿命比（NfR）和拉伸强度比（TSR）的预测模型，以获得最佳的纳米熟石灰含量。最后，根据形成除冰剂的矿物的结果，获得了两个新的最佳除冰器，并将其对TSR和NfR的影响与上述三个除冰剂进行了比较。结果表明，乙酸钙镁饱和样品的TSR和NfR高于NaCl和乙酸钾饱和样品的TSR和NfR。而且，通过用纳米熟石灰改变沥青的性质，增加了无粘附能，无内聚能和脱键能的量，这表明骨料和沥青之间的锁合增加。通过使用能量色散X射线测试确定构成除冰剂的矿物，制得了两种比除NaCl和乙酸钾性能更好的除冰剂化合物。通过优化遗传编程方法中的添加剂百分比（由于更高的准确性），1。
