Engineering Standards

Specifications for constructing steel, concrete, and timber highway bridges using the Load and Resistance Factor Design (LRFD) methodology. E-book.

Intended for use in the design, evaluation, and rehabilitation of bridges.

Includes current research on LRFD calibration, loads, and resistances plus relevant specifications from other AASHTO documents. Completely new sections on Fabrication, Construction, Inspection, and Asset Management based upon best practices have also been added. E-book.

Provides a state-of-the-practice method for the design and analysis of new and rehabilitated pavement structures, based on mechanistic-empirical (ME) principles.

Helps planners and designers determine appropriate design dimensions based on project-specific conditions and existing and future roadway performance more than on meeting specific nominal design criteria. E-book.

Contains specifications, test methods, and provisional standards commonly used in the construction of highway facilities. E-book.
