AASHTO M 304-11 (2019) PDF Download

AASHTO M 304-11 (2019) is a standard specification that pertains to polyvinyl chloride (PVC) profile wall drain pipe and fittings. This standard covers both perforated and nonperforated pipe and fittings with a nominal inside diameter ranging from 100 to 1200 mm (4 to 48 inches). The primary purpose of this specification is to provide guidelines for the use of PVC pipes and fittings in non-pressure storm drains, culverts, underdrains, and other subsurface drainage systems where joints need to be either watertight or soiltight.

It is important to note that before installing PVC pipes and fittings for industrial waste disposal lines, it is necessary to obtain specific approval from the governing code authority. This is because such lines may encounter chemicals not commonly found in drains, as well as temperatures surpassing 60°C (140°F).

To ensure proper installation, it is recommended to adhere to ASTM D 2321 guidelines and follow the manufacturer's instructions for pipe and fitting installation.
