Background 5 • Shear connectors provided only at the transverse panel-to-panel joints and at a relatively wide spacing of 4 ft, 11 in. This simplified the production of the precast panels, as no shear pockets were created in the panel.

Background 7 Based on the experimental investigation conducted at the University of Nebraska–Lincoln, the Nebraska Department of Roads -- now the Nebraska DOT -- used a full-depth precast deck panel system on the Kearney East Bypass Bridge in Kearney, Nebraska (Morcous et al.

8 Simplified Full-Depth Precast Concrete Deck Panel Systems tests focused on evaluating the AASHTO minimum longitudinal and transverse stud spacing, while the fatigue tests focused on evaluating the AASHTO shear stud constant amplitude fatigue limit. The test results showed that, regardless of the spacing between the clusters, the specimens were unable to reach the nominal design strength.
