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 the replacement of deteriorated decks. The report summarizes the construction activities,static load tests,and the present physical conditions of the two field installations constructed during the summer of 1970. This investigation has shown that precast prestressed concrete bridge decks provide a durable deck which can be constructed in a minimum amount of time. The actual time require to place the plank was two days at both field installations. Static load tests and visual inspections have indicated no significant changes in deck performance over the past five years.
