AASHTO M 245-20涵盖了用于雨水排水、地下排水沟、涵洞施工和类似用途的聚合物预涂层波纹钢管。本规范涵盖的管道通常不用于运输生活或工业废物。用于制造管道的钢板在锌（镀锌）、55铝锌合金或锌-5%铝混合稀土合金的金属涂层上具有聚合物保护涂层。与金属涂层相比，聚合物涂层为管道提供了一定程度的额外保护，防止磨损和腐蚀- 无聚合物涂层的涂层管道。某些恶劣环境可能会导致附件（如没有聚合物涂层的铆钉或耦合带硬件）出现腐蚀问题。如M 190所述，在管道制造后，可使用涂层为聚合物预涂层波纹钢管提供额外保护。本规范不包括垫层、回填要求，也不包括覆土荷载和管道板厚之间的关系。 经验表明，该产品的成功性能取决于板材厚度、垫层和回填类型的正确选择、工厂的受控制造以及安装过程中的谨慎。AASHTO公路桥梁标准规范第二部分第26节描述了安装程序。

AASHTO M 245-20 covers polymer-precoated corrugated steel pipe intended for use for storm water drainage, underdrains, the construction of culverts, and similar uses. Pipe covered by this specification is not normally used for the conveyance of sanitary or industrial wastes. The steel sheet used in fabrication of the pipe has a polymer protective coating over a metallic coating of zinc (galvanizing), 55 aluminum-zinc alloy, or zinc-5 percent aluminum-Mischmetal alloy.The polymer coating provides a degree of extra protection for the pipe against abrasion and corrosion as compared to metallic-coated pipe without polymer coating. Some severe environments may cause corrosion problems to accessory items such as rivets or coupling band hardware that does not have a polymer coating. Additional protection for polymer-precoated corrugated steel pipe can be provided by use of coatings applied after fabrication of the pipe as described in M 190.This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and sheet thickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection of sheet thickness, type of bedding and backfill, controlled manufacture in the plant, and care in the installation. The installation procedure is described in AASHTO's Standard Specifications for Highway Bridges, Division II, Section 26.
