“…Asphalt mixture is widely used in road construction, and its quality has a crucial impact on road service life, driving safety, and comfort [1][2]. However, in cold weather during winter, road icing, snow accumulation, and other factors pose significant safety hazards and economic losses to road traffic [3]. Therefore, deicing salt is widely applied in road ice and snow removal, which works by melting ice and snow on the surface and preventing them from freezing again [4].…”

Although the extensive use of deicing salt has solved the problem of road icing in winter and reduced traffic accidents, it has also had a significant impact on the asphalt mixture. Through dry-wet cycle test, this study investigated the change rule of air voids and permeability coefficient of asphalt mixture under the conditions of different gradation, different deicing salt solutions and different dry-wet cycle times, and analyzed the significant indicators of each factor's impact on air voids and permeability coefficient based on variance analysis. The results showed that the air voids and permeability coefficient of AC-13 and AC-16 asphalt mixtures increased to varying degrees after 0, 5, 10, 15, 20, 25, and 30 dry-wet cycles in 20% NaCl, 15% CH4N2O, and 20% CH2CH3OH solutions, and the air voids and permeability coefficient had a high correlation. Meanwhile, the variance analysis results indicated that gradation was the main factor affecting the air voids and permeability coefficient, followed by the dry-wet cycle times, and deicing salt solutions were the least significant.

“…This might have been due to the cracking of the interface between the asphalt layer and the aggregate caused by the crystallization expansion of the deicer in the freeze-thaw environment. The cracks allowed more water to infiltrate the asphalt binder and the total, reducing the splitting strength (Meng et al, 2022).…”

Deicing agents are widely used to remove ice and snow on airport pavement, ensuring air traffic operation and safety. However, excessive spraying may affect the performance of airport pavement. The effects of different chloride deicing agents on the performance of airport asphalt and mixture have been assessed by previous studies. The three deicing agents (NaCl, KHF-1A, and NW056) were selected. Conducting various tests to examine their influence on the performance of asphalt and asphalt mixture. The tests include the DSR test, BBR test, indirect tensile test, bending test of small beam, and freeze-thaw splitting test. The results indicate that the asphalt anti-rutting factor G*/sinδ varies by 25%–45%, the asphalt creep stiffness increases by 15%–50%, and the anti-fatigue factor (G* sinδ) increases by 10%–40% under the effect of the deicing agents. The splitting strength of the mixture decreases by 10%–40%, the bending stiffness modulus increases by 6%–20%, and the freeze-thaw splitting strength ratio does not change significantly under the effect of the deicing agents. NW056 deicing agent has minimal effect on the performance of airport pavement and has optimal performance. The replacement of traditional chloride deicing agents helps to prolong the service life of airport asphalt pavement.

“…Zhang et al [38] pointed out that selecting granular anti-freezing agents can alleviate the adverse effects of salt release on pavement performance. The impact of anti-freezing materials on the pavement performance of asphalt mixtures is mainly related to factors such as the dosage [39][40][41], type [42,43], application method [44], and gradation type [45] of deicing agents.…”

Self-melting ice asphalt pavement materials inhibit pavement freezing and improve driving safety. This paper aims to study the long-term salt release characteristics of self-melting ice asphalt mixtures and the impact on pavement after complete salt release. Firstly, a method to accelerate the rapid release of salt based on the Los Angeles abrasion tester. Then, long-term salt release patterns were elucidated under the influence of deicing agent dosage, type of asphalt, and type of gradation. Finally, a quantitative analysis of the pavement performance after complete salt release is conducted. The results indicate that the release efficiency of the Los Angeles abrasion tester method has increased by 91 times compared to the magnetic stirrer immersion flushing method and by 114 times compared to the natural soaking method. The SBS-modified self-melting ice asphalt mixture possesses a longer duration of salt release, but the uniformity of salt release is inferior. Salt release duration is directly proportional to the dosage of deicing agents. SMA-13 self-melting ice asphalt mixture exhibits poorer uniformity in salt release. After complete salt release, high-temperature stability of self-melting ice asphalt mixtures decreased by 31.6%, low-temperature performance decreased by 15.4%, water stability decreased by 26.7%, and fatigue life decreased by 35.9%.
