Detailed Tables of Contents precede each section. References follow each section, listed alphabetically by author. Figures, tables, and equations are denoted by their home article number and an extension, for example 1.2.3.4.5-1, but when they are referenced in their home article or its commentary, they are identified only by the extension. For example, in Article 1.2.3.4.5, Eq. 1.2.3.4.5-2 would simply be called “Eq. 2.” When this equation is referenced anywhere else other than its home article, it is identified by its whole nomenclature; in other words, “Eq. 1.2.3.4.5-2.” The same convention applies to figures and tables. Please note that the AASHTO materials specifications (starting with M or T) cited throughout the LRFD Specifications can be found in Standard Specifications for Transportation Materials and Methods of Sampling and Testing, adopted by the AASHTO Highway Subcommittee on Materials. Unless otherwise indicated, these citations refer to the current 25th edition. ASTM materials specifications are also cited. Please note that this year marks the final SI edition of the AASHTO LRFD Bridge Design Specifications. In the future, the book will only be published in customary U.S. units. Note also that this time Section 8, “Wood Structures,” is in customary U.S. units. AASHTO apologizes for any inconvenience to wood bridge designers working in SI units.
