Laboratory Tests of Prestressed Concrete Deck Planks and Deck Assemblies
For the past decade prestressed concrete deck plank forms have been used to a limited extent with a cast-in-place topping for bridge deck construction. These planks become an integral part of the deck through composite action with the topping. Normally the planks are 3 inches thick, and a 4-1/2 inch topping is used. During construction the planks are used as the bottom forms and are placed on a grout bed on the top of the prestressed concrete bridge beams. A series of laboratory tests were performed on deck planks and deck plank assemblies. The main purpose of these tests was to determine the composite action between the planks and topping with and without mechanical shear connectors, and to evaluate the different joint types between planks. It was determined that a scored surface on the planks was sufficient to develop composite action. All joint types exhibited similar behavior and load transfer capability.
