Abstarct: Road pavement is considered a national asset of any country, and a large part of the construction budget is spent on repairing and maintaining the pavement. One of the main problems in this regard is the negative effects of de-icing in susceptible areas, mainly mountainous ones, which, in addition to wasting a lot of financial resources, causes many casualties. Unfortunately, currently, the traditional method of pouring a mixture of sand and salt on the asphalt is the only method used in most regions of the country and has many disadvantages. So that it causes a wide level of pollution, as well as damage to vegetation and other environmental waste, as well as destruction of the pavement. The formation of ice and snow on the surface of the pavement is a recurring problem that causes dangerous driving conditions and also has adverse economic effects. One of the solutions that is mainly used in winter to prevent the surface of the pavement from freezing is the timely use of de-icing chemicals on the surface of the pavement to prevent dangerous conditions from occurring. Therefore, in this research, in a laboratory environment with a refrigerator and a microwave, defrosting of asphalt samples with salt and calcium acetate additives along with the proposed material iron ore powder was studied in asphalt samples. In this research, different asphalt samples with different melting and freezing cycles were studied with three methods of salt and calcium acetate and microwave at different percentages of 2, 5, 10 and 20 percent. According to the results, it is observed that by arranging the percentage of iron ore from 2 percent to 10 percent, the weight loss of the asphalt mixture sample in 10 melting and freezing cycles decreased, and then by increasing the percentage of iron ore to 15 and 20 percent, the weight loss of the mixture increased. Therefore, according to the results, it can be concluded that the percentage of 10 percent iron ore is the most desirable amount to be used in the asphalt mixture sample.
