Asphalt concrete material and preparation method thereof
The invention belongs to the technical field of asphalt concrete, and particularly relates to an asphalt concrete material and a preparation method thereof. The asphalt concrete material comprises asphalt, coarse aggregate, fine aggregate, modified basalt fiber, vinyltris (methylethylketoximino) silane and an auxiliary agent, in the process that the basalt fiber is modified through a modification liquid, the surface of the basalt fiber is covered and combined with organic silicon through the modification liquid, the wear resistance of the surface of the basalt fiber is enhanced, and the service life of the asphalt concrete material is prolonged. The hydrophobic performance is enhanced, certain dispersion stability is improved, then modification is carried out through the modifier, surface modification is carried out through boric acid ester, the bonding strength of the particle surface and asphalt is improved, good bonding performance is obtained, and the wear resistance of the pavement is further enhanced.
本发明属于沥青混凝土技术领域，具体涉及一种沥青砼材料及其制备方法。本发明中的沥青砼材料包括沥青、粗集料、细集料、改性玄武岩纤维、乙烯基三丁酮肟基硅烷、辅助剂，本发明通过改性液对玄武岩纤维进行改性过程中，通过改性液实现了对玄武岩纤维表面进行有机硅的覆盖并结合，增强了其表面的耐磨性能，增强了疏水性能，并且提高了一定的分散稳定性，随后通过利用改性剂进行改性，通过硼酸酯表面改性，改善了对颗粒表面与沥青结合力度，获得良好的结合性能，进一步的增强了路面的耐磨性能。
