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 the AASHTO 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.
