Wave-absorbing asphalt mixture capable of rapidly repairing asphalt pavement cracks and preparation method thereof
The invention discloses a wave-absorbing asphalt mixture capable of rapidly repairing asphalt pavement cracks, the wave-absorbing asphalt mixture comprises the following raw materials in parts by weight: modified asphalt, coarse aggregate, fine aggregate, lignocellulose and filler, the filler is a mixture of a wave-absorbing material and mineral powder, and the wave-absorbing material is at least one of carbon black powder, carbonyl iron powder and nickel zinc ferrite powder; the microwave sensitivity of the asphalt mixture is improved through the doped wave-absorbing material, the microwave absorption capacity of the asphalt pavement is enhanced, the working efficiency of repairing the asphalt pavement cracks through microwave heating is greatly improved, and the problems existing in the application of a microwave heating technology in the field of road maintenance are effectively solved. The adopted wave-absorbing material has good compatibility with the asphalt mixture, replaces part of mineral powder with different volume fractions to be added into the asphalt mixture to form the wave-absorbing asphalt mixture, and has a synergistic effect with the asphalt mixture coarse aggregate with a good dielectric constant, so that the electromagnetic parameters and the electric heating performance of the asphalt mixture are improved; the microwave absorptivity of the asphalt mixture is improved, and good pavement performance of the asphalt mixture is ensured.
本发明公开了一种可快速修复沥青路面裂缝的吸波沥青混合料，原料按重量份改性沥青、粗集料、细集料、木质纤维素、填料，所述填料为吸波材料与矿粉的混合物，所述吸波材料为炭黑粉、羰基铁粉、镍锌铁氧体粉中的至少一种；通过掺入的吸波材料提高沥青混合料对微波的敏感性，增强了沥青路面微波吸收能力，极大地提升微波加热修复沥青路面裂缝的工作效率，有效解决了微波加热技术应用于道路养护领域中存在的问题。所采用的吸波材料与沥青混合料具有很好的相容性，替代部分不同体积分数的矿粉加入到沥青混合料中形成吸波沥青混合料，并与介电常数好的沥青混合料粗集料协同作用，改善了沥青混合料电磁参数和电热学性能，提高了沥青混合料微波吸收率，并保证了沥青混合料良好的路用性能。
