BRIDGE REPLACEMENTS WITH PRECAST CONCRETE PANELS

Methods of replacing existing distressed bridge deck slabs with precast concrete panels are presented. The general nature of the problem is explored, and the nature of force transfer in a bridge deck system is examined. The various methods of connection between adjacent slab panels and between the slab and stringer are then developed on a rational basis. Eight types of slab-stringer connections are detailed. Many of these would developed composite action. Some connections are welded, and others are bolted. Several types of shear connectors are used. A construction method is suggested that (a) presents a rehabilitated structure that is compatible in strength to the original, (b) provides rapid construction that causes minimal interference to normal traffic, and (c) allows full traffic capacity to be maintained during peak periods.
