Investigation and Assessment of Long-Span Corrugated Steel Plate Culverts

A scheme for reviewing the condition of long-span corrugated metal culverts is outlined. The scheme assesses the significance of observed pipe deformations. The scheme has been used successfully in Elgin County, Ontario, to assess culvert performance and to assist in the management of repair and rehabilitation work. Specific measurements are given for 39 culverts with a range of spans, heights, and culvert shapes. Details are given of the culvert ranking, and the courses of action for structures judged to be in need of treatment.
