Use of Precast-Prestressed Concrete for Bridge Decks.

摘要

A precast,prestressed concrete bridge deck system has been designed to be used either on new bridges or for reconstruction of deteriorated decks. The report describes the construction activities involved in the use of the prestressed plank on two installations in Indiana. Actual time required to place the elements and post-tension them together was two days for each bridge. Load tests have been made on both bridges at intervals since their construction. Results have indicated no significant changes in deck performance during this period.
