“…Electric heating methods include laying carbon nanotubes [15] and carbon fiber heating line [16] under pavement, using the electrothermal properties of these materials to heat the road to melt snow and ice [17]. In order to improve the efficiency of snow and ice melting, researchers studied the influence of heating material layout, electric power, and environmental factors on the efficiency of snow and ice melting [18][19][20]. As for other bridge structures, researchers pay more attention to the effects of ice accretion on the aerodynamics of bridge structures; the results of their experiments show that the ice accretion can obviously increase the wind-induced response of bridge structures, which will deteriorate the wind-resistant performance of bridges [21][22][23][24] and even cause catastrophic failure to bridges [25].…”

The cross beam of a long-span bridge will freeze in low temperature. When the temperature rises, the ice on the cross beam will thaw and fall off. If the ice is too heavy, it may cause vehicle damage and casualty. In order to reduce the risk of falling ice, a scale model of the cross beam was taken as an example, and a kind of numerical simulation method is presented to study the icing distribution characteristics on surface of the cross beam. This paper simulates the ice accretions process of the cross beam by Fluent module and FENSAP-ICE module of ANSYS and investigates the influence of wind and temperature in the process. This is a new numerical simulation method for studying ice accretions of buildings. The results indicate that water freezes mainly on the windward surface, and the thicker ice is near the top and bottom edge of windward surface. According to the results of numerical simulation, a measure of ice melting based on electric heating method is proposed in this paper, and the feasibility and effectiveness of this method are verified by numerical simulation. The results show that the icing distribution characteristics are accord with the fact and the ice-melting measure is feasible and effective.

“…Some scholars study how to improve the performance of bitumen and asphalt mixture to avoid negative effect [2][3][4]. At the same time, some methods of deicing and melting snow on the pavement have been researched, such as asphalt mixture containing the snow-melting agent [5], hydraulic heating system [6][7][8][9][10], electrically conductive concrete [11][12][13], carbon fiber grille [14], and CFHW [15][16][17][18][19]. e recent research of deicing and melting snow on the pavement mainly focuses on the CFHW [1].…”

In the paper, the method of deicing and melting snow by the carbon fiber heating wire (CFHW) embedded in the airport asphalt pavement is proposed to improve the security of airport operation. The field experiment of deicing and melting snow on the airport asphalt pavement is conducted. Deicing and melting snow, asphalt pavement temperature, ice-free area ratio, and snow-free area ratio are analyzed. Electrical power with 350 W/m2 is input to the airport asphalt pavement for deicing and melting snow by the CFHW. In the experiment, 3 mm ice can be melted, and the average infrared ray temperature (IRT) of the airport asphalt pavement surface can achieve an increment of 13.0°C in 2.5 hours when the air temperature is from −7.5°C to −2.2°C. Snow with 3.2 mm precipitation can be melted in 2 hours when the air temperature is from −4.8°C to −3.5°C, and the asphalt pavement temperature can achieve an increment of 5.9°C at the depth of 0.5 cm. The results show that the method of deicing and melting snow on the airport asphalt pavement by the CFHW is practicable in the cold zone.
