Abstract: 本研究深入探讨不同纤维对纤维增强混凝土(FRC)桥面铺装层与桥面间粘结性能的影响。通过制备多种含不同纤维类型及掺量的FRC试件，运用拉伸试验、剪切试验等方法测定其粘结性能指标。结果显示，不同纤维对粘结性能影响显著，钢纤维可大幅提升拉伸粘结强度，合成纤维在一定程度上改善剪切粘结性能。研究成果为FRC在桥面铺装工程中的科学应用提供了关键依据，有助于优化桥面铺装设计，增强桥梁结构的耐久性与安全性。This study deeply explores the influence of different fibers on the bonding performance between the fiber-reinforced concrete (FRC) bridge deck pavement layer and the bridge deck. By preparing various FRC specimens containing different types and dosations of fibers, the bonding performance indicators were determined by methods such as tensile tests and shear tests. The results show that different fibers have a significant impact on the bonding performance. Steel fibers can greatly enhance the tensile bonding strength, and synthetic fibers improve the shear bonding performance to a certain extent. The research results provide a key basis for the scientific application of FRC in bridge deck pavement engineering, which is conducive to optimizing the design of bridge deck pavement and enhancing the durability and safety of bridge structures.
