摘　　要：为提高道路的融雪除冰效率,实现冬季道路雪后快速畅通,对基于微波与磁铁耦合效应的融雪除冰技术进行了试验研究。首先测定了磁铁矿集料的技术性质和磁铁矿沥青混凝土的路用性能;其次通过微波发热试验对比分析了普通集料和含磁铁集料的微波发热效率;最后通过室内除冰试验分析了磁铁矿沥青混凝土的微波除冰效率。结果表明:磁铁矿沥青混凝土路用性能能够满足规范要求;磁铁矿集料的微波发热效率约为普通集料的20倍;磁铁矿沥青混凝土的微波除冰效率约为普通沥青混凝土的10～30倍。In order to improve the microwave deicing efficiency of cleating the ice on the road rapidly, the deicing tech- nology of asphalt pavement based on microwave and magnet coupling effect was studied by tests. First, the technologi- cal property of magnetite aggregate and magnetite asphalt concrete were tested. Second, the microwave-heated tests were put forth to analyze the heated efficiency of conventional and magnetite aggregates. Finally, the microwave deicing efficiency of asphalt concrete was studied by the laboratory tests. The results showed the technological property of mag- netite asphalt concrete could meet the requirements according to specification. The microwave-heated efficiency of magnetite aggregates was about 20 times of conventional aggregates. The microwave deicing efficiency of magnetite asphalt concrete was about 10-20 times of conventional asphalt concrete.
