AASHTO M 175M/M 175-05 (2020) PDF Download

AASHTO M 175M/M 175-05 (2020) is a standard specification that specifically addresses the use of perforated concrete pipe for underdrainage applications. The standard outlines the requirements and specifications that such pipes must meet in order to ensure their quality and efficacy in drainage systems. These pipes are designed to allow water to enter through the perforations, which are evenly distributed along the length of the pipe, to facilitate effective water drainage.

The standard provides guidance on various aspects of perforated concrete pipe, including dimensional requirements, material properties, and performance characteristics. It specifies the allowable tolerances and limits for dimensions such as outside diameter, wall thickness, and length to ensure consistency and compatibility with existing drainage systems. The standard also outlines the required specifications for the concrete mixture used in the pipe manufacturing process, including compressive strength and water absorption limits.

Additionally, AASHTO M 175M/M 175-05 (2020) addresses the testing and inspection requirements for perforated concrete pipes. It provides information on the testing methods to be used for determining the quality and performance of the pipes, such as hydraulic efficiency and resistance to external loads. The standard also includes guidelines for the inspection of the pipes during manufacturing, transportation, and installation to ensure compliance with the specified requirements.
