706.06 Perforated Concrete Pipe

1. Specification:

706.06 C&MS.

S 1074

2. Sampling and/or Inspection Requirements:

Certified Plant Sampled and Tested Materials:

Sampling is not be required. Material is tested and accepted under certification program S 1074. The Certified Supplier list is on the OMM website @ http://www.dot.state.oh.us/Divisions/ConstructionMgt/Materials/Pages/default.aspx. Materials from non-certified suppliers will not be accepted.

Inspect pipe upon delivery to the project for dimensions and condition. Pipe dimensions shall comply with the appropriate 706.01 or 706.02 tables, depending on the pipe. Perforation dimensions shall be checked for conformance with Table 1 - 706.06. A TE-24 Shipping Notice must be received with the material. If the material fulfills the requirements it may be used immediately. (Field)

If the material does not fulfill the requirements, it shall be rejected. Send a copy of the TE-24 to the Det and notify OMM, Concrete Section.

Any pipe may be rejected containing a spall more than 3/4-inch in diameter or 3/16-inch in depth caused by making the perforation or slot.

Perforations may be Type 1-circular, or Type 2 - slotted. Either type may be used unless otherwise specified.

Each pipe shall be clearly marked in accordance with the class and type specified.

3. Method of Test:

(OMM)

ASTM C 444
