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, \u201cCurrent Provisions and Needed Research for Lightweight Concrete in Highway Bridges\u201d (FHWA-HRT-07-051).96
