1047.3.2 The pipe shall be Type S and not be perforated unless specified otherwise.

1047.3.3 Field joints shall provide circumferential and longitudinal strength to maintain the pipe alignment,

prevent separation of pipe and prevent infiltration of fill material. Coupling bands, if used, shall be of the same base material as the pipe. Corrugations in the bands shall have the same configuration as the corrugations in the pipe ends being connected. Prior to use, the design of coupling bands and fastening devices shall be submitted to and approved by Construction and Materials. Final acceptance of coupling bands and fastening devices will be based on field performance.

1047.3.4 The manufacturer shall provide to the engineer an itemized statement of the sizes, section properties

and lengths of pipe in each shipment.

1047.3.5 Pipe may be fabricated using English units of measurement. Pipe fabricated using English

measurements shall meet the diameter dimensions shown on the plans. Pipe tolerances will be in accordance with AASHTO M 294 or AASHTO M 335.

1047.4 Sampling, Testing and Acceptance Procedures. All manufacturers furnishing pipe meeting the

requirements of AASHTO M 294,for MoDOT projects shall be qualified as described herein. All manufacturers furnishing pipe meeting the requirements of AASHTO M 335 for MoDOT projects shall meet the quality control and assurance requirements of the appendix section in M 335 and these specifications. All pipes will be subject to inspection by the engineer at the source of manufacture, at an intermediate shipping terminal or at destination. The engineer shall be allowed unlimited access to all facilities and records as required to conduct inspection and sampling in accordance with Sec 106.

1047.4.1 Application for Placement on Qualified List.

1047.4.1 1 To become qualified to furnish pipe meeting AASHTO M 294, a written request shall be sent by the

manufacturer to Construction and Materials, and shall include the following information:

1047.4.1 2 To become qualified to furnish pipe meeting AASHTO M 335, a written request shall be sent by the

manufacturer to Construction and Materials with the following:

1047.4.1 2.1 Manufacturer’s QC Plans. The QC plan for each plant furnishing AASHTO M 335 pipe shall

include the following:
