INNOVATIVE BRIDGE PANEL SYSTEM A SUCCESS

This article describes testing and evaluation of partial-depth, cast-in-place (CIP) decks with stay-in-place (SIP) precast concrete panel systems. This system was proven to have the following advantages: (1) It eliminates field forming for deck overhangs. (2) For rehabilitation of bridge decks, it saves the time and labor needed to rearrange the shear connectors. (3) It saves time and labor because the SIP panel covers the entire width of the bridge. (4) The SIP precast panel can be crowned to form a cross slope surface of the bridge. (5) The SIP precast panel is designed to support the paving machine loads and a construction load in addition to its self-weight and the topping slab self-weight. (6) The materials used in the production of the panel are non-proprietary and are inexpensive. (7) The reinforced pockets in the transverse direction between the precast panel help to provide continuity in the longitudinal direction, resulting in minimization of the reflective cracks at the transverse joints. (8) The system has a far superior performance than the conventional SIP panel system under cyclic load. (9) The system has almost double the flexural capacity of the conventional SIP panel system.
