Title: NEW FOLDED-PLATE BRIDGE CULVERT SYSTEM
Accession Number: 00611775
Record Type: Component
Availability: Find a library where document is available Abstract: A new precast concrete bridge/culvert system is described. The system is particularly suitable for a roadway crossing over a waterway, where the span is relatively short (20 to 60 ft), and the clearance between the high water level and roadway surface is greater than 6 ft. The system can be built quickly by most contractors, making it an attractive alternative for replacement of many of the nation's deficient secondary road bridges and culverts. It consists of precast concrete folded-plate elements supported on ledges of end walls, which are in turn supported on drilled piers. Variations of this basic system are possible to suit other span ranges and crossing geometries. The system is extremely efficient as its components use available space to increase structural cross section depth and to reduce dead loads that would otherwise be heavy. Other benefits are offered by this new system, including short construction time, economy, and ease of construction. The new system is compared with an existing system; a cost analysis demonstrates potential savings as high as 20% over the traditional system. Plans are under way to construct a full-scale functional prototype in eastern Nebraska.
