Self-healing asphalt concrete under microwave action and preparation method thereof
The invention provides a preparation method of asphalt concrete capable of rapidly heating and self-healing under the action of microwaves. The microwave self-healing asphalt concrete is prepared from 83.8 wt%-89.6 wt% of steel slag aggregate, 2.3 wt%-7.9 wt% of steel slag powder, 2.8 wt%-12.8 wt% of wave-absorbing modified asphalt and the like. Wherein the coarse and fine steel slag aggregate, the steel slag powder and the wave-absorbing asphalt are mixed to form the asphalt concrete. The loss factor of the asphalt concrete under microwaves is increased, when the microwaves act on a damaged pavement of the microwave self-healing asphalt concrete, the steel slag aggregate, the steel slag powder, the wave-absorbing modified asphalt and the like have dielectric loss and magnetic loss on the microwaves, and the asphalt concrete converts microwave electromagnetic energy into heat energy; the asphalt concrete is rapidly and uniformly heated to 45-85 DEG C through heating for a certain time, and rapid self-healing of the asphalt concrete is realized by utilizing the thermal repair effect of asphalt.
本发明提供一种在微波作用下可快速升温自愈合的沥青混凝土的制备方法。所述微波自愈合沥青混凝土由钢渣集料、钢渣粉、吸波改性沥青等制备而成，83.8％～89.6wt％，钢渣粉2.3％～7.9wt％，吸波改性沥青2.8％～12.8wt％。其中，将钢渣粗细集料、钢渣粉和吸波沥青经过拌合形成沥青混凝土。沥青混凝土在微波下的损耗因子提高，当微波作用于该微波自愈合沥青混凝土的损坏路面时，钢渣集料、钢渣粉、吸波改性沥青等对微波有介电损耗和磁损耗，沥青混凝土将微波电磁能转化为热能，通过一定时间加热使沥青混凝土快速、均匀升温至45～85℃，利用沥青的热修复作用，实现沥青混凝土的快速自愈合。
