Design Examples for Large-Span Culverts
Flexible and rigid large-span culverts, typically ranging from 3 to 9 m (10 to 30 ft), are often a practical structure for crossings, especially on local road systems. The use of these structures is growing, and the available design and construction specifications related to them are in need of improvement. Large-span culverts are complex structures whose design and performance are related to the interaction of the structure and the surrounding soil. Properties of the backfill envelope as well as in situ material have a major effect on the performance of these structures, and additional knowledge about these effects is needed. This is especially true now that new construction materials, such as special fills, are being used. The objective of this research is to develop recommended design, construction, and installation criteria and specifications for flexible and rigid large-span culverts. These specifications will be consistent in philosophy and format with the AASHTO LRFD Bridge Design Specifications and will be accompanied by a commentary.
