Anti-cracking, anti-freezing and wear-resistant layer for bridge pavement and preparation method thereof
The invention discloses an anti-crack anti-freezing wear-resistant layer for bridge pavement. The anti-crack anti-freezing wear-resistant layer is prepared from basalt fibers, anti-freezing microcapsules, aggregate, mineral powder, asphalt and cement. The anti-freezing microcapsule is prepared by taking ethyl cellulose powder and graphene oxide as wall materials and taking N-vinyl pyrrolidone as a core material. According to the anti-cracking, anti-freezing and wear-resistant layer for bridge pavement disclosed by the invention, the basalt fibers are used for improving the toughness of the pavement layer, and the basalt fibers and the anti-freezing microcapsules are used for improving the low-temperature anti-cracking property of a mixture. The anti-freezing microcapsule can be heated by microwaves to remove ice, and the N-vinyl pyrrolidone of the capsule core is exposed and can expand in volume when meeting water to block the crack, so that the anti-cracking and anti-permeability performances are further improved.
本发明公开了一种桥梁铺装抗裂抗冻耐磨层，包括以下原料：玄武岩纤维、抗冻微胶囊、集料、矿粉、沥青、水泥；所述抗冻微胶囊是以乙基纤维素粉末、氧化石墨烯作为壁材，以N‑乙烯基吡咯烷酮作为芯材制得。本发明公开的桥梁铺装用抗裂抗冻耐磨层，使用玄武岩纤维提高铺装层的韧性，和抗冻微胶囊一起提高了混合料的低温抗裂性。抗冻微胶囊可使用微波加热除冰，并且囊芯N‑乙烯基吡咯烷酮暴露，遇水可发生体积膨胀，将裂缝封堵，进一步提高了抗裂抗渗性能。
