About this file
This is a specification sheet from the Missouri Department of Transportation (MoDOT) for corrugated metallic-coated steel culvert pipe and related appurtenances intended for maintenance purposes. The specification covers the materials, dimensions, and ordering requirements for corrugated metal culvert pipe, pipe-arches, and end sections. Acceptable pipe configurations include either 2 2/3 by 1/2 inch or 3 by 1 inch corrugations, with metallic coating options of either zinc or aluminum as specified in the order. All pipe ends must feature 2 2/3 by 1/2 inch annular corrugations extending at least 4 corrugations from the pipe end. Metal arch pipes B1 through B4 must comply with AASHTO M 36 dimensional requirements. Connecting bands shall be annular corrugated with a minimum width of 24 inches unless otherwise specified in the order, with alternate band types including dimple or formed options when permitted.
The specification requires that specific diameter, quantity, and length information be provided in the purchase order, with pipe lengths specified in 2-foot increments. Acceptable diameters are referenced in Specification Section 725. The metallic coating type—whether zinc or aluminum—must be explicitly designated in the order if a specific coating is required. Material acceptance will be conducted in accordance with Specification Section 1020, with compliance required to applicable sections of Specifications 725, 1020, and 1022 as noted in the document.
