Use of High Performance Concrete for an Adjacent Box Beam Bridge Guernsey County, Ohio
As part of FHWA's multi-state SHRP High Performance Concrete (HPC) Implementation Program, a highway bridge in Ohio originally designed using normal concrete as a three-span adjacent box girder structure was able to be redesigned as a single-span HPC adjacent box girder bridge (referred to as the Ohio HPC Showcase Bridge) by using 70 Mpa HPC and 15 mm diameter strands. This report documents the steps taken to design two HPC mixes required for the project: (1) a 70 MPa (10,000 psi) mix for the prestressed concrete box girders; and (2) a 56 MPa (8,000 psi) mix for the cast in place parts of the bridge (e.g. abutments). Because a number of material performance and fabrication issues needed to be resolved, two extensively instrumented prototype HPC box girders were fabricated and tested. The fabrication of these members was extensively documented and proved quite feasible and economical. The material testing of the HPC verified the improved durability, strength, stiffness and behavior of the high performance concrete produced.
