Temporary Bridge Deck Panels

The research described here has resulted in the development of a simplistic and innovative interlocking glulam bridge deck panel for use in temporary bridge deck applications. The key feature of this panel system is the interlocking tongue and groove joint. The joint provides both displacement compatibility and structural load transfer between panels. The unique structural tongue and groove design successfully addresses two common issues with existing transverse glulam bridge decks: (1) It reduces differential movement between panels which is a very common problem with noninterconnected glulam deck systems in use today; and (2) It allows the deck system to be installed completely from the top, eliminating the need for workers to install bolts from underneath the bridge deck. Other design advantages of the panels include: prefabrication for rapid on site installation, reusability, and because they are made from wood, the panels are relatively lightweight and have a relatively high strength to weight ratio when compared to steel and concrete alternatives.
