这些指导规范描述了玻璃纤维增强聚合物（GFRP）复合材料的独特材料特性，以及GFRP钢筋加固混凝土桥面和栏杆的设计和施工规定。本修订版包括材料规范的进步信息，以及桥面和交通栏杆以外的新知识和现场经验。新版中的一些主要更新包括与2009年第一版《AASHTO LRFD GFRP桥梁设计指南规范》的标题变更- 钢筋混凝土桥面和交通栏杆，以确认包含桥面和交通栏杆以外的信息；与ASHTO LRFD桥梁设计规范（第8版）更一致；第一版中未包括的受弯构件，如大梁和盖梁；考虑受压构件的下部结构和基础构件的考虑；区分疲劳和蠕变极限状态；以及修订的剪力设计方法。

These guide specifications offer a description of the unique material properties of glass fiber reinforced polymer (GFRP) composite materials, as well as provisions for the design and construction of concrete bridge decks and railings reinforced with GFRP reinforcing bars. This revised edition includes information on the advancements in material specifications, and new knowledge and field experiences beyond bridge decks and traffic railings.Some of the major updates in this new edition include a title change from the 2009 first edition,AASHTO LRFD Bridge Design Guide Specification for GFRP-Reinforced Concrete Bridge Decks and Traffic Railings, to acknowledge the inclusion of information beyond bridge decks and traffic railings; greater consistency with theAASHTO LRFD Bridge Design Specifications, 8th Edition; consideration of flexural members, such as girders and bent caps, not included in first edition; consideration of substructure and foundation elements along with compression members; differentiation between the fatigue and creep limit states; and revised shear design methodology.
