Abstract
An improved article and method for making and installing a bridge deck replacement system. Subsystem articles include a plurality of precast slabs which contain features, notably projections and plates which depend from the underside thereof, which are used to form both haunch forms/molds and grout engaging devices. When used in conjunction with the conventional and preestablished supporting structure subsystem, the slabs, though use of the various devices included and/or depending therefrom, non-shrink grouting and the improved method of installation, are securable thereto and, yet, may be severally and/or discretely removed at a later time and replaced with new slabs. The replacement facility is obtained concomitant with the attainment of an overall system having a truly composite action in that slabs and support structure subsystems function as a singular unit.
