Project completed in April 2021 using ceEntek's ce200SF-G
The lateral post-tensioning in this 50+ year old bridge had corroded and deteriorated to a condition where all post-tensioning forces had disappeared and the side-by-side box-girders were no longer performing as an integral unit. There was a significant reduction in the ability for load sharing by adjacent girders.
FDOT decided to use hydro-demolition to remove the old grout between the box-girders, install new dowel bars, and cast UHPC to provide lateral connections between the box-girders and re-establish load-sharing.
During removal of the old asphalt, the sub-contractor removed a portion of the top concrete cover protecting the steel stirrups in the box girders. An emergency repair using ce200SF-t overlay was installed.
