纤维增强聚合物（FRP）桥面板已成为一种有趣的替代方案，它们在现有桥梁的翻新和新建桥梁的建设中的应用越来越受到关注。轻质、高强度FRP材料给这些应用带来的好处是众所周知的。然而，采用FRP桥面板的桥梁概念的可持续性仍然需要证明和验证。本文的目的是通过与传统桥梁概念进行比较，检查这些FRP解决方案的可持续性来弥合这一知识差距。为此，选择了一座带有混凝土桥面的现有组合（钢-混凝土）桥。研究和分析了两种情况：整个桥梁上部结构的全部更换和用GFRP制成的新桥面板更换混凝土桥面板。分析证明，FRP桥面板有助于在桥梁的生命周期内节省潜在的成本，并减少对环境的影响。
Fibre reinforced polymer (FRP) bridge decks have become an interesting alternative and they have attracted increasing attention for applications in the refurbishment of existing bridges and the construction of new bridges. The benefits brought by lightweight, high-strength FRP materials to these applications are well recognised. However, the sustainability of bridge concepts incorporating FRP decks still needs to be demonstrated and verified. The aim of this paper is to bridge this knowledge gap by examining the sustainability of these FRP solutions in comparison with traditional bridge concepts. An existing composite (steel–concrete) bridge with a concrete deck that had deteriorated was selected for this purpose. Two scenarios are studied and analysed; the total replacement of the entire bridge superstructure and the replacement of the concrete deck with a new deck made of GFRP. The analyses prove that FRP decks contribute to potential cost savings over the life cycle of bridges and a reduced environmental impact.
