This website was created to educate others about a new bridge deck construction method that removes the need for formwork placement and wrecking, accelerates construction, simplifies the grading of bridge decks and improves safety for construction workers by allowing a top down construction approach.
This concept was conceived at the Texas Department of Transportation (TxDOT) Bridge Division by Tyler Ley and Ralph Browne in the Fall of 2004 on the back of an envelope. Several key details were developed and tested in TxDOT research project 6100 under the guidance of Ricardo Gonzalez and Ralph Browne. This research was completed at Texas A&M University (PI: David Trejo) and Oklahoma State University (PI: Tyler Ley) with the help of Jim Abrams, Jr. of Austin Prestressed.
In the Summer of 2009 this bridge deck system was constructed at the Rocky Creek Bridge in Parker County, Texas. The project was a success and TxDOT is actively looking for other projects to implement the latest version of the bridge deck system. This concept has been further investigated and successfully improved under a research grant to Oklahoma State University by the Oklahoma Transportation Center.
It is the goal of this website to provide a web presence for this concept to educate others and also provide a vehicle to provide new information on this technology. If you can not find the answer to your questions here then please post a question in our forum or send us an e-mail.
