Application and effect evaluation of deck pavement in road and bridge maintenance
桥面铺装在道路桥梁维护中的应用与效果评估

摘要

桥面铺装属于道路桥梁关键的结构构成部分，它不但肩负着交通荷载传递的作用，还会直接对桥梁的结构耐久性、行车舒适性产生影响。本文针对桥面铺装的材料种类、施工技术、养护管理办法展开了系统的剖析，并且结合国内外桥梁维护的实际情况，对其在延长桥梁使用期限、降低维护成本、提高交通安全性方面所起到的作用进行了评价。研究结果表明，传统沥青铺装适合应用于中短跨距、交通流量适中的桥梁，其施工具有灵活性，成本较低，然而耐久性存在一定的局限性，水泥混凝土铺装适合用于长跨距、高等级桥梁，具有较高的耐久性和承载能力，不过施工比较复杂。通过对施工工艺加以优化，对质量管理予以严格把控、进行科学的维护，可以有效减少桥面病害的出现，提高结构安全性、行车舒适度，与此同时降低全寿命周期成本，为道路桥梁工程的管理与维护提供科学的依据、实践的参考。

Abstract

The bridge deck pavement is a critical structural component of road and bridge systems, serving not only to transmit traffic loads but also directly influencing the structural durability and driving comfort of bridges. This study systematically analyzes the material types, construction techniques, and maintenance management methods of bridge deck pavements. By considering the actual conditions of bridge maintenance both domestically and internationally, it evaluates the role of these pavements in extending service life, reducing maintenance costs, and enhancing traffic safety. The findings indicate that traditional asphalt pavements are suitable for medium to short-span bridges with moderate traffic volumes, offering flexible construction and lower costs but with certain durability limitations. In contrast, cement concrete pavements are appropriate for long-span and high-grade bridges, providing superior durability and load-bearing capacity but requiring more complex construction. Through optimized construction processes, strict quality control, and scientific maintenance, the occurrence of deck diseases can be effectively reduced, improving structural safety and driving comfort while lowering lifecycle costs. This study provides a scientific basis and practical reference for the management and maintenance of road and bridge engineering.
