Precast, Pretensioned, Post-Tensioned Concrete for Bridge Decks

The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con­ cept of construction or reconstruction which we hope will contribute considerably to the durability of concrete bridge decks and greatly reduce the time required for replacement of deteriorated bridge decks.
