Since about 1974, ASTM has published standard specifications for precast reinforced concrete box culvert sections. These standard specifications included tabulated reinforcing designs for a variety of sizes and earth cover depths, as well as manufacturing requirements and procedures for quality control. This paper chronicles the history and development of these ASTM standards published under the jurisdiction of ASTM C13 Committee on Concrete Pipe, with a focus on the specific methods used to develop the reinforcing tables and changes to the specifications with time to reflect industry consideration of design code changes. We provide details behind the withdrawal of the older specifications and the creation and passing of newer standards for box culvert sections. This paper also examines the history of the ASTM specifications with respect to AASHTO materials standards and design codes.
