High performance concrete (HPC) with higher compressive strength (in the range of 8,000 to 10,000 psi) and increased durability is rapidly gaining acceptance for bridge construction. The goal of this project was to implement and demonstrate the economic benefits of the HPC technology in bridge design and construction in North Carolina, thereby providing a greater value to the public. Specifically, the project monitored the production of HPC in typical plant and field conditions, confirmed the feasibility of producing HPC bridge girders and decks, and validated the expected behavior of bridge superstructures built with HPC girders and decks.

The objective of this research was to evaluate the current design specifications for use on prestressed, High Performance Concrete (HPC) bridge girders. An AASHTO Type IV and modified BT-56 girders were constructed with a 10,000 psi HPC to which a composite 7000 psi HPC deck was cast on top. The composite girders were tested in flexure, with the Type IV being tested to failure. The results of the flexure tests showed that the current AASHTO Specification for cracking moment and ultimate capacity are conservative. In addition to flexural testing, each composite girder was studied with respect to the deck contraction induced girder deflection. Each deck and girder were instrumented with strain gauges and string potentiometes. The results of the study indicated the induced deflections are significantly greater than deflections from the deck dead load, and should be considered to accurately predict bridge deflection.

This report establishes a user's manual for the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. The report also proposes revisions to the AASHTO LRFD Bridge Design Specifications and provides recommendations to develop improved crack control reinforcement details for use in new girders. The material in this report will be of immediate interest to bridge engineers.
