Abstract Compared with traditional deicing method, microwave deicing method has advantages of high energy utilization rate, good deicing effect, environmental protection and economy. In order to improve the microwave deicing efficiency of iced pavement, a microwave heating test of asphalt mixture is designed based on microwave pavement mechanism, which proves the theoretical feasibility of microwave deicing technology. Based on the microwave heating test of the type and content of absorbing materials, the superiority of the absorbing material ferric aluminum mixture (mixing Al2O3 and Fe3O4 with 1:1) and hydroxy iron powder RW as microwave deicing sensitive materials is determined, and the optimal blending mass ratios are 1% and 5%. Then the optimal materials at different microwave frequencies are obtained. When the microwave frequency is 2.45 GHz, the ferric aluminum mixture with a mass ratio of 1% is preferably added. When the microwave frequency is 5.8 GHz, the hydroxy iron powder RW with a mass ratio of 5% is preferably added. Finally, the reliability of road performance is verified, which indicates that the development of the new microwave sensitive material can improve the efficiency of microwave deicing and provide theoretical guidance for the application of microwave deicing technology.

不同频率微波除冰路面用新型敏感材料的研制及性能研究

摘要 与传统除冰方法相比，微波除冰方法具有能量利用率高、除冰效果好、环保、经济等优点。为提高结冰路面的微波除冰效率，基于微波路面机理设计了沥青混合料微波加热试验，证明了微波除冰技术的理论可行性。通过对吸波材料种类和含量的微波加热试验，确定了吸波材料三价铁铝混合物（Al2O3和Fe3O4按1:1混合）和羟基铁粉RW作为微波除冰敏感材料的优越性，并确定了最佳的吸波材料。混合质量比为1%和5%。然后得到不同微波频率下的最佳材料。当微波频率为 2.45 GHz 时，优选加入质量比为1％的三价铁铝混合物。当微波频率为5.8GHz时，优选加入质量比为5％的羟基铁粉RW。最后验证了道路性能的可靠性，表明开发新型微波敏感材料可以提高微波除冰效率，为微波除冰技术的应用提供理论指导。
