This specification covers the requirements and methods of tests for steel-reinforced polyethylene (PE) ribbed pipe, couplings, and fittings for use in surface and subsurface drainage applications.
Nominal sizes of 300 to 900 mm (12 to 36 in.) are included.
Materials, workmanship, dimensions, pipe stiffness, impact resistance, tensile strength of seams, shape stability, joining systems, and form of markings are specified.
Steel-reinforced PE ribbed pipe is intended for surface and subsurface drainage applications where soil provides support to its flexible walls. Its major use is to collect or convey drainage water by open gravity flow as culverts, storm drains, etc.
Note 1: When PE pipe is to be used in locations where the ends may be exposed, consideration should be given to protection of the exposed portions due to combustibility of the PE and the effects of prolonged exposure to ultraviolet radiation.
This specification only deals with this pipe’s materials requirements. There is no currently accepted AASHTO design methodology for this pipe, and the users of this pipe must assure themselves that this pipe material will perform adequately under installation and design methods chosen by the user. This specification does not include requirements for bedding, backfill, or earth cover load. Successful performance of this product depends upon proper type of bedding and backfill, and care in installation. Appropriate construction and installation procedures are provided by Section 30 of the AASHTO LRFD Bridge Construction Specifications. Upon request of the user or engineer, the manufacturer shall provide profile wall section detail required for a full engineering evaluation.
