Ferrite asphalt mixture with microwave snow melting function and preparation method and application thereof
The invention relates to a ferrite asphalt mixture with a microwave snow melting function and a preparation method and application thereof. The ferrite asphalt mixture comprises the following components in percentage by mass: 85.5-89.5% of coarse and fine aggregates, 2.1%-7.9% of mineral powder; 4.8%-5.3% of asphalt; 3.4%-6.8% of zinc manganese ferrite powder; and 0.01-0.3% of fiber. Asphalt and other mixtures are mixed so that the zinc-manganese ferrite powder is uniformly dispersed in the asphalt mortar and is laid on a roadbed. Compared with the prior art, after the ferrite powder is subjected to microwave heating, microwave electromagnetic energy can be converted into heat energy so that the surface temperature of the asphalt mixture is rapidly and uniformly increased to 5 DEG C from-20 DEG C, and an effective snow melting function can be achieved for an accumulated snow pavement; the asphalt mixture doped with the ferrite powder has the advantages that the heat conductivity coefficient is increased by 0.4-0.8 W/(m.K) compared with the original heat conductivity coefficient, the heat conduction capability of the pavement is effectively improved, and the snow melting function isenhanced.
本发明涉及一种具有微波融雪功能的铁氧体沥青混合料及其制备方法和应用，包括以下质量分数的各组分：粗细集料85.5％～89.5％；矿粉2.1％～7.9％；沥青4.8％～5.3％；锌锰铁氧体粉末3.4％～6.8％；纤维0.01～0.3％。沥青及其他混合料经过拌和，使锌锰铁氧体粉末均匀的分散在沥青胶浆中，并铺设于路基上。与现有技术相比，本发明中铁氧体粉末经过微波加热后，可以将微波电磁能转化为热能，使沥青混合料表面温度从‑20℃快速均匀增加至5℃，对于积雪路面可以实现有效的融雪功能；掺加了铁氧体粉末的沥青混合料，导热系数较原来增加了0.4～0.8W/(m·K)，有效增加了路面的热传导能力，加强融雪功能。
