As the interstate system deteriorates, traffic volumes increase and construction related traffic delays are at an all time high, there arises a need to greatly expedite highway, road and bridge construction projects. Bridge deck replacements account for a large percentage highway construction that can create thousands of hours of traffic delays due to full and partial closures.
A deck replacement systems was designed and tested utilizes full depth (8.5&inches;) concrete panels post tensioned longitudinally with high strength steel bar. The transverse panel joint is a tongue and groove, sealed with a 6 hour pot life thyxotropic epoxy. The method was designed to allow for full traffic flow over a bridge during the day and in the evening partially close to allow for sectional replacement of the existing deck. The research was a collaborative effort between the NHDOT and UNH.
