Program Purpose:

This project deals with the development of a system for constructing deck slabs for highway bridges that arex000D
lighter, faster to construct, more durable, and more economical than conventional deck slabs built ofx000D
cast-in-place concrete. Using the proposed system, deck slabs are assembled from modular prefabricated panelsx000D
constructed from ultra high-performance concrete (UHPC). This is a new material that improves onx000D
conventional concrete by offering higher compressive strength, a reliable tensile strength, and extremely lowx000D
permeability. This enables the deck slab panels to be composed of a relatively thin slab with monolithic ribs inx000D
two orthogonal directions, thus making the panels significantly lighter than conventional solid deck slabs.x000D
x000D
The work to be accomplished in this project is to determine the most optimum dimensions for the concretex000D
panels and arrangement of reinforcement. This will be accomplished by analytical and experimental means,x000D
including full-scale load tests.
