AASHTO M 278-22
This specification covers the requirements and methods of test for smooth-wall perforated and unperforated poly(vinyl chloride) (PVC) plastic pipe, couplings, and fittings for use in subsurface drainage and surface drainage (culverts) of transportation facilities, where soil support is given to its flexible walls in all applications. It includes provisions for solid wall and solid wall coextruded poly(vinyl chloride) (PVC) plastic pipe. Solid wall coextruded pipe has three layers including a center layer and concentric inner and outer layers. The inner and outer layers are made of virgin or reworked PVC compound and the center layer has external recycled PVC content.
Nominal sizes of 100 to 375 mm in a stiffness class designated as PS46 are included.
Materials, dimensions, flattening, impact resistance, pipe stiffness, extrusion quality, joining systems, perforations, and form of marking are specified.
