1.1 This specification covers corrugated steel structural plate, polymer-coated, used in the construction of pipe, pipe-arches, arches, underpasses, and special shapes for field assembly. Appropriate fasteners and accessory materials are also described. The pipe, arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels. 1.2 This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and plate thickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection of plate thickness, type of bedding and backfill, manufacture in the plant, and care in the installation. The purchaser shall correlate the preceding factors and also the corrosion and abrasion requirements of the field installation with the plate thickness. The structural design of corrugated steel structural plate pipe and the proper installation procedures are described in Practices A796/A796M and A807/A807M. 1.3 This specification is applicable to orders in either inch-pound units (as AXXX) or SI units (as AXXXM). Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text, but they are the applicable values when the material is ordered to AXXXM. 1.4 This specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.

The proposed standard will mimic A761 except that a polymer coating option is provided in lieu of the zinc coating option. A polymer coating will provide a more durable option for the more severe environmental conditions faced by road authorities in cross culvert and buried bridge applications.Back to Top
