AASHTO M 252-20 PDF Download

AASHTO M 252-20 is a standard specification that outlines the requirements and testing methods for corrugated polyethylene drainage pipe. This standard is applicable to various applications such as subsurface drainage systems, storm sewers, and surface drainage (culverts), where the pipe is supported by soil.

The standard covers nominal sizes ranging from 75 to 250 mm (3 to 10 inches). It specifies the materials, dimensions, pipe stiffness, environmental stress-crack resistance, perforations, joining systems, and forms of marking that are required for corrugated polyethylene drainage pipe.

It also provides a note of caution regarding the use of PE pipe in locations where the ends may be exposed. It suggests considering the combustibility of the polyethylene material and the potential deteriorating effects of prolonged exposure to ultraviolet radiation.
