Concrete Decks

Abstract

Figure 15.4 shows full-depth precast concrete deck panels under construction. e full-depth precast panels have the advantages of signicant reduction of shrinkage eects and fast construction speed and have been used for deck replacement with high trac volumes. NCHRP Report 407 (Tardos and Baishya 1998) proposed a full-depth panel system with panels pretensioned in the transverse direction and posttensioned in the longitudinal direction. NCHRP Report 584 (Badie and Tardos 2008) developed two full-depth precast concrete bridge deck panel systems, a transversely pretensioned system and a transversely conventionally reinforced system and proposed guidelines for the design, fabrication, and construction of full-depth precast concrete bridge deck panel systems without the use of posttensioning or overlays and (2) connection details for new deck panel systems.
