Recommended AASHTO LRFD Tunnel Design and Construction Specifications

The AASHTO LRFD Bridge Design Specifications, Section 12--Buried Structures and Tunnel Liners provides little information on the design and construction of highway tunnels. Although the American Association of State Highway Transportation Officials (AASHTO) adopted the Federal Highway Administration (FHWA) Technical Manual for Design and Construction of Road Tunnels--Civil Elements, design and construction specifications for tunnels are needed considering existing manuals and specifications, especially those developed FHWA and the National Fire Prevention Association (NFPA). The objective of this research is to develop stand-alone recommended design and construction specifications for highway tunnel systems. In developing these specifications, consideration shall be given to safety and operations, maintenance, and inspection of tunnel systems. The research will produce design and construction specifications with commentary in the format of the AASHTO LRFD Bridge Design Specifications.
