AASHTO HB-17: Standard Specifications for Highway Bridges, 17th Edition (2002)
AASHTO HB-17: Standard Specifications for Highway Bridges, 17th Edition (2002) provides comprehensive criteria for the design, construction, and maintenance of highway bridges throughout the United States. This edition is the final update prior to the nationwide adoption of Load and Resistance Factor Design (LRFD) standards.
Highlights:
- General provisions for bridge design, structural analysis, and performance
- Criteria for superstructures, substructures, abutments, culverts, and piers
- Service load and load factor design methods for concrete, steel, timber, and prestressed components
- Requirements for foundations, retaining structures, and soil-structure interaction
- Specifications addressing load distribution, fatigue, seismic considerations, and strength evaluation
- Commentary and notes incorporating interim revisions through 2003
- References to supporting standards from AASHTO, ASTM, AWS, and others
- Applicable to rehabilitation, legacy design validation, and maintenance planning for non-LRFD bridges
Who It’s For:
A critical reference for bridge engineers, transportation officials, and contractors working with legacy structures or evaluating designs developed before the transition to LRFD.

ANSI Z535.4-2011 (R2017): Product Safety Signs and Labels
ANSI Z535.4-2011 (R2017): Product Safety Signs and Labels provides standardized guidance for the design and application of product safety signs and labels. This reaffirmed edition helps manufacturers effectively communicate hazard information to reduce risk and improve safety across a wide range of industrial and consumer products.
Highlights:
- Defines use of standardized signal words: DANGER, WARNING, CAUTION, and NOTICE
- Establishes hazard classification systems and formatting conventions
- Specifies layout, safety colors, symbols, and typography for clear communication
- Offers guidance on incorporating safety symbols for universal understanding
- Sets durability requirements for labels exposed to harsh environments
- Recommends best practices for label placement and visibility
Who It’s For:
A vital reference for engineers, product designers, compliance managers, and safety professionals responsible for labeling products in accordance with ANSI safety communication standards.
