桥面铺装层作为桥梁系的一部分,相对于桥梁其他部分它直接承受行车荷载、梁体变形和环境因素的作用。其变形和应力特征与主梁及桥面板结构形式密切相关,一方面可分散荷载并参与桥面板的受力;另一方面起联结各主梁共同受力的作用。既是主梁的保护层,又是桥面结构的共同受力层。所以混凝土桥面铺装层应具有足够的强度和良好的整体性,并具有足够的抗渗性、抗裂性、抗冲击性和耐磨性。桥面铺装层施
Bridge deck as a part of the bridge system, relative to other parts of the bridge it directly bear the traffic load, the beam deformation and environmental factors. Its deformation and stress characteristics are closely related to the structure of the main girder and the bridge deck. On the one hand, it can disperse the load and participate in the force of the bridge deck; on the other hand, it acts as a joint force for connecting the main girders. It is both the protective layer of the main beam and the common force layer of the deck structure. Therefore, the concrete deck pavement should have sufficient strength and good integrity, and has sufficient impermeability, crack resistance, impact resistance and wear resistance. Bridge deck facilities
