Low-temperature microfiber ice-coagulation-resistant modified asphalt concrete and preparation method thereof
The invention provides low-temperature microfiber ice-coagulation-resistant modified asphalt concrete and a preparation method thereof, and relates to the technical field of asphalt concrete.The low-temperature microfiber ice-coagulation-resistant modified asphalt concrete is formed by mixing aggregate, epoxy modified asphalt, fibers, a water repellent agent, an anti-freezing agent, nano metal oxide and a self-repairing agent according to the mass ratio, the hydrophobic agent and the anti-freezing agent are arranged, so that the asphalt concrete has good hydrophobic performance, water is not prone to permeating into the asphalt concrete, or water is not prone to remaining in the asphalt concrete or on the surface of the asphalt concrete, and when the temperature is low, the surface or the interior of the asphalt concrete is not prone to freezing; the basic wear resistance and friction resistance of the asphalt concrete can be guaranteed, the anti-freezing agent is matched for use, and when the temperature is low, sodium chloride and magnesium chloride in the anti-freezing agent can be slowly released under the action of water, so that the freezing point of the water is reduced, and the asphalt concrete pavement is further prevented from being frozen.
本发明提供了一种低温超纤抗冰凝改性沥青混凝土及其制备方法，涉及沥青混凝土技术领域，低温超纤抗冰凝改性沥青混凝土采用集料、环氧改性沥青、纤维、疏水剂、抗凝冰剂、纳米金属氧化物、自修复剂按质量比混合而成，本发明通过设有疏水剂和抗凝冰剂，使得沥青混凝土具有良好的疏水性能，水不易渗透进入沥青混凝土内部，或者水不易在沥青混凝土内部和表面停留，在温度较低时，沥青混凝土表面或内部不易结冰，能够保证沥青混凝土基本的耐磨和耐摩擦性能，配合使用抗凝冰剂，温度低时，抗凝冰剂中的氯化钠氯化镁能够在水的作用下缓释出来，从而降低水的凝固点，进一步防止沥青混凝土路面结冰的产生。
