An improved continuous stay-in-place (CSIP) precast prestressed concrete panel system is developed. This system eliminates some of the drawbacks of the conventional stay- in-place (SIP) precast panels. The precast panel can cover the entire width of the bridge. Therefore, it eliminates the necessity of forming for the overhangs and results in reduction of time and labor required to install a large number of pieces. The precast panel has a full-length gap at the girder lines to maximize the space needed to accommodate the shear connectors of the supporting girders. The precast panel is continuous over the girder with an innovative reinforcement system. Shear keys and reinforced pockets are used in the transverse direction to provide continuity between the precast panels. The precast panel can be crowned to follow the cross slope profile of the bridge. All materials used in producing the precast panel are nonproprietary and readily available which makes this system cost comparable to that of the conventional SIP precast system. Complete details of the system, including design procedure, construction steps, testing program and references, are given.
