FULL-SCALE TESTING OF SEAL SLAB/PILE INTERFACE BOND. IN: LARGE-SCALE STRUCTURAL TESTING

The goal of this study was to recommend bond values for the interface between seal slabs and piles that could be used in the Florida Department of Transportation specifications. The values were to be based on full scale tests on specimens prepared in accordance with the current FDOT specifications for commonly encountered conditions. The pile embedment depth, pile surface, pile material (steel or concrete), and the type of fluid displaced by the concrete were some of the variables examined. This study provides the first experimental data from full scale tests to evaluate the seal slab/pile interface bond, and the results have been readily incorporated into the latest FDOT design specifications.
