Abstract: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. This report corresponds to the TechBrief titled, “Current Provisions and Needed Research for Lightweight Concrete in Highway Bridges” (FHWA-HRT-07-051).
