Successful performance of this product depends upon proper type of bedding and m2944, and care in installation. Fabricated fittings shall be supplied with joints compatible with the overall system. Certification, if desired Aasgto The stub compression test, AASHTO Tshall be aashti material and wall design qualification test conducted twice a year or whenever there are changes in wall design or material distribution.
We want to hear from you. The plant must have an approved laboratory, either within the company or an independent laboratory. The manufacturer shall have current calibration records for the automated or manual weigh-blending equipment. Other types of coupling bands or fastening devices that are equally effective as those described, and that comply with the joint performance criteria of AASHTO LRFD Bridge Construction Specifications, Section 30, may be used when approved by the purchaser.
Customary units are shown in parentheses, and may not be exact equivalents.
The specifying agency may require an annual third-party independent assurance test. The designated quality control technicians will be responsible for overall quality control at the producing plant. Group 2 June 1. Click here to buy this book in print or download it as a free PDF, if available. It is not necessary for the individual components of the blend to meet the cell class or NCLS requirements of this standard, provided that the final blend meets all the requirements.
Built using application-specific high-density polyethylene, dual wall N corrugated pipe also provides superior corrosion and abrasion resistance. The rows of perforations shall be arranged in two equal groups placed symmetrically on either side of the lower unperforated segment corresponding to the flow line of the pipe. The design of the fittings shall be such that when connected with the pipe, the axis of the assembly will be level and true when tested in accordance with Section 9.
The corrugated PE pipe covered by this specification is classified as follows: Pipe connected by bell and spigot joints may not be perforated in the area of the bells and spigots. Class 1 perforations are for pipe intended to be used for subsurface drainage or combination storm and underdrain. For this condition, the average UCLS failure time for five specimens shall not be less than 34 hrs. Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book.
Soiltight joints are specified as a function of opening size, channel length, and backfill particle size. Make linear measurements with instruments accurate to 0. The methods of identification for each lot of material during manufacture, testing, storage, and shipment.
If a date code is used, a durable manufacturer sticker that identifies the actual date of manufacture shall be adhered to the inside of each length of pipe. Only fittings supplied or recommended by the pipe manufacturer shall be used. The plant designation code; and J which simplifies to: A plan for dealing with nonconforming product, including how the producer plans to initiate immediate investigation and how corrective action will be implemented to remedy the cause of the problem.
The blended sample shall not contain carbon black concentrate. Titles of the personnel responsible for production quality at the plant s ; X1. Use the form below to send us your comments or questions: If pipe is made from a non-PPI certified resin or non-PPI certified blend of component resins, the pipe manufacturer should have a resin testing program in place that includes the testing of each component resin and resin blend lot for density and melt index and have the means of conducting in-house or contract lab the remaining cell class and NCLS testing as specified in this standard.
The point shall be considered as the 0. Split couplings shall engage at least two full corrugations on each pipe section. Type of pipe Section 4. Two classes of perforations are as described in Sections 7. Jump up to the previous page or down to the next one.
Corrugated PE pipe is intended for surface and subsurface drainage applications where soil provides support to its flexible walls. Samples of materials and pipe may be zashto by the specifying agency.
The research consisted of manufacturing several large diameter corrugated HDPE pipes out of various blends of virgin and post-consumer recycled PCR materials commonly used in land drainage applications and evaluating these pipes in the field and qashto to determine their service life in typical installed conditions.
Couplings shall be bell and spigot or split collar.

Class of perforations Class 2 is furnished if not specified Section 7. It is permissible to run the pipe stiffness test in conjunction with the pipe flattening test as long as individual evaluations are made for their respective criteria as specified under Sections 7. Upon request of the user or engineer, the manufacturer shall provide profile wall section detail required for a full engineering evaluation.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Perforations shall be uniformly spaced along the length and circumference of the pipe.
