Abstract

Selection of appropriate pavements Deicing materials is one of the main concerns of roads maintenance officials. Investigations show that many researches have been carried out on effects of Deicing/anti-icing materials on concrete, however a few researches have evaluated the effects of these materials on Asphalt mixtures and these few researches have generally concentrated on moisture susceptibility of Asphalt mixtures. In the current study, Asphalt mixtures specimens were compacted by gyratory compactor and then were cut into semi-circular specimens. Each of specimens was subjected to water and sodium chloride (NaCl), calcium chloride (CaCl2), calcium magnesium chloride (CMA) and potassium acetate (KA) solutions. Fracture Toughness of specimens was measured at three temperatures of 0,-10 and-20 ° C using semi-circular bending (SCB) specimen test. Tests results showed that the effects of Deicing materials on Fracture Toughness of Asphalt mixture specimens were different at three temperatures. At the temperature of 0 ° C, the destructive effect of Deicing materials on the Fracture Toughness of the Asphalt mixtures was not observed, while at the temperatures of-10 ° C or-20 ° C, some of Deicing materials could decrease the Fracture Toughness of the Asphalt mixtures. Meanwhile the moisture susceptibility tests results indicated that the Deicing materials had no destructive effect on the moisture susceptibility of the Asphalt mixtures.
