Phạm vi áp dụng / Scope of standard

This specification covers corrugated steel structural plate,
zinc-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.

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 must correlate
the above 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 AASHTO Standard
Specifications for Highway Bridges, Division I, Section 12 and
Division II, Section 26, respectively.

The values stated in either SI units or inch-pound units are to
be regarded separately as standard. Within the text, the inch-pound
units are shown in brackets. The values stated in each system are
not exact equivalents; therefore, each system shall be used
independently of the other. Combining values from the two systems
may result in nonconformance with the specification.
