Development of High Performance Concrete Mixture for Tennessee Bridge Decks
One possible solution to the problem of bridge deck deterioration is the use of high-performance concrete (HPC). By carefully selecting and combining high-quality ingredients and understanding the effects of these ingredients on the concrete's overall durability performance, Departments of Transportation (DOTs) may be able to produce concrete that is more durable and less expensive than the concrete they are currently using and that meets all of their specifications. Currently, the Tennessee Department of Transportation (TDOT) uses strength, slump, air content, cement content, and maximum aggregate size as the main parameters to specify Class D concrete mix as the standard bridge deck mix in Tennessee. While these are important parameters to satisfy the physical property requirements, such as the compressive strength, they are not sufficient to ensure long-term durability, especially in the area of chloride ion permeability. Therefore, TDOT sponsored a research project (Phase I) at the University of Tennessee to develop HPC mixes for possible adoption for use in bridge decks. As a result of the first year of investigation, an interim final report was presented to TDOT in December 2004.
