The AASHTO LRFD Bridge Design Specifications and the AASHTO LRFD Bridge Construction Specifications were reviewed to identify provisions that affect the use of lightweight concrete. A synthesis of research relevant to the provisions was then compiled. Proposed research problem statements were developed to generate data to update the specifications in areas where gaps exist for lightweight concrete. / NOTE: Final Rept., Nov. 2006-May 2007. / Supplementary Notes: Sponsored by the Federal Highway Administration, McLean, VA. / Availability Note: Available on CD-ROM and in color paper copy only.
