Current Provisions and Needed Research for Lightweight Concrete in Highway Bridges

This TechBrief summarizes a synthesis report on completed research and current American Association of State Highway and Transportation Officials (AASHTO) provisions related to lightweight concrete used in highway bridges. The synthesis report is intended to provide a reference point for a Federal Highway Administration (FHWA) research program aimed at addressing perceived shortcomings in the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications and the AASHTO LRFD Bridge Construction Specifications pertaining to lightweight concrete. The synthesis report also makes recommendations for future research efforts, focusing on the use of lightweight concrete in bridge structures.
