FHWA Lightweight High-Performance Concrete Research Program

This paper describes an ongoing FHWA research program focused primarily on LWHPC in the gap of equilibrium densities ranging from conventional lightweight to normal weight concrete. The program involves testing 27 AASHTO girders and 40 rectangular beams to (i) investigate the performance of LWHPC produced using aggregates representative of those available in North America, (ii) investigate the transfer length, development length, and shear strength of precast/prestressed LWHPC members, (iii) study the development and splice length of mild steel reinforcement used in LWHPC, and (iv) investigate prestress losses in LWHPC girders. The result of the study will be to recommend changes to the AASHTO LRFD Bridge Design Specifications relevant to LWHPC.
