Full Depth Precast, Prestressed Concrete Bridge Deck System

This study presents a new full depth precast, prestressed concrete bridge deck panel system. The newly developed system includes stemmed precast panels, transverse grouted joints, longitudinal post-tensioning and welded threaded and headless studs. The purpose of the system is to provide a high quality bridge deck that can be built rapidly for new construction or rehabilitation. Rapid reconstruction time reduces the traffic disruption and annoyance that bridge users may encounter. The new system is shown to have better crack control and to be 10% more slender and 20% lighter in weight than solid conventional reinforced concrete decks.
