1908 - POLYETHYLENE (PE) PIPE 1900-13
1908.1 Description
This specification covers polyethylene pipe for storm sewers and culverts.
1908.2 Requirements
a. Polyethylene Pipe. Provide polyethylene (PE) pipe for stor m sewers and culverts that complies with one of the following:
1.AASHTO M 294 (Corrugated Pipe) with the following additions or exceptions: Only Type S is acceptable. Rotational Molded Pipe will not be accepted.
2.ASTM F 894 (Ribbed, Profile) with the following additions or exceptions: AASHTO LRFD Bridge Design Specifications, SECTION 12, 50 year life requirements. Minimum Cell Class per ASTM D 3350 of 334433C or 335434C. Minimum section properties as noted in SECTION 12.
3.ASTM F 714 (Smooth Wall) with the following additions or exceptions: A DR of 21 or less will be required. AASHTO LRFD Bridge Design Specification, SECTION 12, 50 year life requirements. Minimum Cell Class per ASTM D 3350 of 335434C.
4.Soil tight joints are required (AASHTO LRFD Bridge Construction Specifications, SECTION 26). Maximum opening is 1 inch. For openings over 1/8-inch, exceed the channel length by four times the length of the opening. Channel length is the length of the path that the soil must infiltrate. The D 85 soil size to size of opening ratio must be 0.3 for medium to fine sand and 0.2 for uniform sands. D85 is the sieve size that 85% of the backfill material is smaller than. b. Joints. To obtain soil tight joints, manufacture the pipe joints to comply with the following: Maximum opening is 1 inch. For openings over ⅛-inch, exceed the channel length by 4 ti mes the size of the opening. Channel length is the length of the path that the soil must infiltrate. c. End Sections. Provide culvert end sections that comply with the sizes and dimensions in the Contract Documents. Fabricate end sections fr om materials that comply with these specifications. Corrugated metal or concrete end sections are also acceptable. Connect dissi milar materials using a soil-tight connection approved by the Engineer. d. Deflection. Maximum deflection (reduction of the barrel base inside diameter) is 5%. Measurement will be made using a mandrel or other method as approved by the Engineer not less than 30 days following the installation. Deflections in excess of 5% may require th e pipe to be removed and reinstalled, or replaced if permanently deformed or damaged in any way.
1908.3 Test Methods
Test materials in accordance with th e AASHTO and ASTM standards cited in subsection 1908.2. 1908 - POLYETHYLENE (PE) PIPE 1900-14
1908.4 Prequalification
Follow the instructions on the AASHTO National Transportation Product Evaluation Program’s (NTPEP) website to participate in the audit program for polyethylene (PE) pipe plants. Forward an official copy of the initial (and latest) NTPEP audit report to the Bureau Chief of Construction and Materials for evaluation. Include copies of the most recent six months of quality control test results. In order to maintain prequalified status, send a copy of the annual NTPEP certificate of compliance as soon as it is received. Plants that have been removed from the NTPEP website listing will be removed from prequalified status. Plants that fail to provide the annual certificate of compliance or are no longer in compliance with the audit requirements may be removed from prequalified status.
1908.5 Basis of Acceptance
Prequalification as specified in subsection 1908.4. Receipt and approval of a Type C certification as specified in DIVISION 2600. Visual inspection for condition and dimensional requirements. Successful testing with a mandrel as outlined in subsection 817.3b.
