lighter, faster to construct, more durable, and more economical than conventional deck slabs built of_x000D_
cast-in-place concrete. Using the proposed system, deck slabs are assembled from modular prefabricated panels_x000D_
constructed from ultra high-performance concrete (UHPC). This is a new material that improves on_x000D_
conventional concrete by offering higher compressive strength, a reliable tensile strength, and extremely low_x000D_
permeability. This enables the deck slab panels to be composed of a relatively thin slab with monolithic ribs in_x000D_
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 concrete_x000D_
panels and arrangement of reinforcement. This will be accomplished by analytical and experimental means,_x000D_
including full-scale load tests., program purpose french : This project deals with the development of a system for constructing deck slabs for highway bridges that are_x000D_
