Nu-Deck Precast Deck Panels And Innovative Bridge Research And Construction, Maher K. Tadros, Charles J. Vranek
Nebraska Department of Transportation: Research Reports
Most of the deficiency in existing stringer-type bridges lie in deterioration of the bridge deck. Cast-in-place reinforced concrete decks experience cracking shortly after construction due to large differential creep and shrinkage with the supporting beams, and due to the temperature drop experienced during the hydration cycle. The NUDECK (Nebraska University) system is a full-depth precast/prestressed concrete bridge deck panel system. The combination of high performance precast concrete, where little creep and shrinkage occur after the deck is made composite with the beams, and two-way prestressing assure continued pre-compression of the deck during its life. With this system, construction time and …

Coupling refers to a flux occurring without its primary thermodynamic driving force; for example, mass flux without a concentration gradient called the thermal diffusion is a well-known coupled process. Coupling also refers to a flux occurring in a direction opposite to the direction imposed by its driving force; for example, a mass flux can occur from a low to a high concentration region and is called the active transport or uphill transport, such as potassium and sodium pumps coupled to chemical energy released by the hydrolysis of adenosine triphosphate (ATP) in biological systems. Although the coupled processes seem to be …
