Abstract:The report contains a research plan to assist in the implementation of high performance concrete in the Charenton Canal Bridge in Louisiana. The research involves a literature review, plan review, development of a quality control program for the concrete, development of an instrumentation plan, and development of a plan to determine concrete properties. ; The literature review concentrates on practical information that can be used in the design and construction of bridges in Louisiana. special provisions which emphasize changes in quality control procedures are developed. The instrumentation plan includes the monitoring of temperature effects, camber and deflections, strains, and prestress losses. The concrete materials test program involves measurements of compressive strength, modulus of elasticity, modulus of rupture, coefficient of thermal expansion, creep shrinkage, and permeability.
