Structural Testing of Field-Cast Ultra-High Performance Concrete (UHPC) Connections between Precast Bridge Deck Level Elements
Project Information
Project ID:
FHWA-PROJ-09-0132
Project Abstract:
UHPC is being considered for use in bridge decks as a cast-in-place joint fill material between precast concrete elements. As part of the Federal Highway Administration's (FHWA's) ongoing UHPC research effort and in support of a UHPC deployment effort by the New York State Department of Transportation (NYSDOT), FHWA has initiated a testing program focused on the behavior of field cast UHPC connections between precast bridge deck elements.
The six slab specimens are designed to model two different situations wherein UHPC might be used as a joint fill or closure pour material. Four of the slabs are designed to mimic the types of connections that might occur between precast bridge deck elements with the joint being perpendicular to the length of the bridge. The remaining two slabs are designed to mimic the type of connection that might occur between the flanges of a pair of deck-bulb-Tee prestressed girders with the joint being parallel to the length of the bridge. Each of these slabs will be tested for two different behaviors; namely performance under cyclic service level loads and performance under monotonic ultimate loads. Loads will be applied vertically along the midline of the span through a 10-inch by 20-inch load patch that simulates a truck wheel load. After the conclusion of the cyclic testing, the slabs will be loaded monotonically to failure. Assessments of specimen cracking and joint performance will be completed throughout the testing.
