The Guide Specification for High Performance Concrete for Bridges is intended to serve as a guide for developing specifications for all high performance concretes supplied for highway bridges. This includes high performance concretes produced by a ready mix supplier, a general contractor, or in a permanent plant of a precast concrete manufacturer. This guide is useful for specifiers, enabling them to easily copy mandatory language into specifications for projects, and also offers guidance on what characteristics and limits should be specified to ensure satisfactory performance for a given element or environment.
