Impregnating compound reinforced basalt fiber suitable for AC-20 asphalt mixture
The invention belongs to the technical field of road engineering materials, and particularly relates to an impregnating compound reinforced basalt fiber suitable for an AC-20 asphalt mixture. The total mass of the required impregnating compound accounts for 6-14% of the total mass of the basalt fiber. Wherein the impregnating compound is prepared from a main film-forming agent, an auxiliary film-forming agent, an antistatic agent, a coupling agent and a lubricating agent, and according to the mass percent, the mass fraction of the main film-forming agent is 28.80%-40.50%, the mass fraction of the auxiliary film-forming agent is 25.60%-38.50%, the mass fraction of the antistatic agent is 0.36%-4.19%, the mass fraction of the coupling agent is 0.72%-15.78%, and the mass fraction of the lubricating agent is 0.36%-7.03%. The reinforced impregnating compound prepared by the preparation method can increase the surface roughness of basalt fibers and improve the interface bonding force between the fibers and asphalt, so that the interface bonding capacity of the asphalt and aggregate is enhanced, and the effects of improving the high-temperature stability, low-temperature crack resistance and fatigue resistance of an asphalt mixture are achieved.
本发明属于道路工程材料技术领域，具体涉及一种适用于AC‑20沥青混合料的浸润剂增强型玄武岩纤维。以质量百分比计，所需浸润剂总质量占玄武岩纤维总质量的6％～14％。其中，浸润剂以主成膜剂、辅成膜剂、抗静电剂、偶联剂、润滑剂构成，以质量百分比计，主成膜剂的质量分数为28.80％～40.50％，辅成膜剂的质量分数为25.60％～38.50％，抗静电剂的质量分数为0.36％～4.19％，偶联剂的质量分数为0.72％～15.78％，润滑剂的质量分数为0.36％～7.03％。本发明在所制备的增强型浸润剂能够增加玄武岩纤维表面粗糙度，改善纤维与沥青之间的界面粘结力，从而增强沥青与集料的界面粘结能力，起到提高沥青混合料的高温稳定性、低温抗裂性及抗疲劳性能的作用。
