Asphalt pavement material additive, self-repairing asphalt pavement and preparation method
The invention relates to an asphalt pavement material additive, a self-repairing asphalt pavement and a preparation method, and belongs to the technical field of self-repairing asphalt. The additive is formed by mixing silver nanowire modified microcapsules and a composite material of an asphalt regenerant and porous calcium carbonate. When asphalt cracks under the external action, the wall of the microcapsule is stimulated to crack, the photo-thermal dual-curing resin system in the microcapsule is released, the resin system flows into the crack, and the photo-thermal dual-curing behavior is generated under the sunlight irradiation and the heat energy converted from the sunlight irradiation, so that the asphalt microcracks are repaired, the asphalt performance is improved, and the service life of the asphalt is prolonged. The service life is prolonged. And the composite material of the asphalt regenerant and the porous calcium carbonate starts to slowly release the asphalt regenerant for a long time when the asphalt pavement is formed, so that aromatic components lacked by the asphalt are compensated in time, and the aging and cracking process of the asphalt is delayed. The two components cooperate with each other to effectively improve the durability and the self-repairing capability of the asphalt pavement.
本发明涉及一种沥青路面材料外加剂、自修复沥青路面及制备方法，属于自修复沥青技术领域。外加剂由银纳米线改性微胶囊、以及沥青再生剂和多孔碳酸钙的复合材料混合而成。当沥青在外界作用下开裂而产生裂纹时，会刺激微胶囊囊壁破裂，释放出其中的光热双重固化树脂体系，树脂体系流动进入裂缝，在太阳光照射下及由太阳光照射转化的热能下发生光热双重固化行为，使沥青微裂纹得到修复，改善沥青性能，延长其使用寿命。而沥青再生剂和多孔碳酸钙的复合材料则在沥青路面形成之时便开始缓慢且长效地释放沥青再生剂，及时弥补沥青缺失的芳香分组分，延缓了沥青老化开裂的进程。二者协同配合，可有效提高沥青路面的耐用性和自修复能力。
