Study on Deicing Efficiency and Surface Temperature Distribution of Concrete Pavement by Microwave Heating
Winter ice and snow pose a serious threat to road traffic,and various traditional deicing methods have certain drawbacks.Microwave deicing is a novel method characterized by its eco-friendliness and high deicing efficiency.This study investigates the surface temperature distribution patterns of concrete during the microwave de-icing process using an open-structure microwave deicing apparatus designed in-house.The results show that the temperature distribution of concrete surface presents the phenomenon of high central area and low surrounding temperature during the process of microwave deicing.The temperature distribution has directionality,and the tem-perature attenuation speed of concrete surface temperature along the long side of microwave source waveguide is fas-ter than that in short side direction.The higher the microwave source height,the lower the temperature of the center point of the concrete surface,the larger the heating range,the better the uniformity of the heating on the concrete surface.When the microwave source height is 40mm,the deicing area of concrete pavement is 83.4 cm2.
