About this file
This is a specification document issued by the Missouri Department of Transportation (MoDOT) for the procurement of corrugated metallic-coated steel culvert pipe and related appurtenances. The specifications establish requirements for corrugated metal culvert pipe, pipe-arches, end sections, and connecting bands used for maintenance purposes. The acceptable products must comply with MoDOT Specifications Sections 725, 1020, and 1022. Pipe may be supplied with either zinc or aluminum metallic coatings and must feature either 2 2/3 by 1/2 inch or 3 by 1 inch corrugations. All pipe ends must have annular corrugations extending at least 4 corrugations from the end, with re-rolling required for certain pipe types. Metal arch pipe types B1 through B4 must meet AASHTO M 36 dimensional requirements. Connecting bands shall be annular corrugated with 2 2/3 by 1/2 inch corrugations and have a minimum width of 24 inches unless otherwise specified in the order.
Orders must specify the required diameter, quantity, and pipe lengths in 2-foot increments, with acceptable diameters identified in Specification Section 725. When a specific metallic coating type is desired, it must be explicitly designated in the order as either "Zinc Coated" or "Aluminum Coated." Alternative band types, including dimple or formed bands, may be substituted when permitted by the order specifications. Material acceptance will be conducted in accordance with MoDOT Specification Section 1020, which establishes quality and compliance standards for delivered products.
