“…The use of additives in flexible and concrete pavements has become popular in recent years. Various studies have shown that additives have been able to improve most of the engineering properties of pavements (Zarei and Zahedi, 2016;Zahedi et al, 2017a;Zahedi et al, 2017b;Zahedi et al, 2020;Janmohammadi et al, 2020;Zarei et al, 2020b;Zarei et al, 2020c;Abdi Kordani et al, 2021;Rassafi et al, 2021;Sodeyfi et al, 2021;Zarei et al, 2021;Zarei et al, 2022a;Zarei et al, 2022b;Zarei et al, 2022c;Za-rei et al, 2022d;Tabasi et la., 2023a;Tabasi et al, 2023b;Xiong et al, 2023;Hos-seini et al 2023;Tabasi et al 2023c;Ziaee et al 2023;Liu et al 2023;Wang et al 2024;Qiu et al 2024;Yang et al 2024).

Weather conditions such as rainfall and freeze-thaw cycles affect the pavement performance of airports; therefore, methods such as using de-icing chemicals are considered in order to maintain the normal condition of the airport runway. In addition to the above factors, de-icing chemicals play an important role in pavement performance and the damage caused to it due to their chemical nature. Therefore, investigating the effect of de-icing chemicals and determining the appropriate material to maintain the airport's pavement is a priority for engineers. In this study, the effect of three de-icing chemicals, sodium chloride, potassium acetate, and ethylene glycol (at concentrations of 23.3%, 49%, and 69.07%, respectively) on skid resistance (The British Pendulum Test (BPT) and The Road Test Machine (RTM)) and the mechanical properties (Compressive Strength Test) of the concrete under Freezing and Thawing Cycle were investigated. The BPT test results showed that sodium chloride resulted in better skid resistance than other chemicals when the number of cycles is more than 100 cycles. This result was also obtained for all cycles in the RTM test. Also, ethylene glycol was not suitable for improving skid resistance based on BPT and RTM tests. Furthermore, the results of the compressive strength of concrete mixtures showed that the de-icing chemicals reduced the compressive strength of concrete mixtures. Based on all the results, sodium chloride had better results than other chemicals.
