Special Specifications
Other Considerations
PDH Questions
• Materials Procedure is in development
• Pipe Diameters of 30” and up
• Round Pipe, Oval Pipe, Boxes, Arches etc.
• Bypass pumping required
• Small construction
equipment footprint
1. Determine the exact dimensions and conditions
2. Thorough cleaning of host pipe.
3. Invert Repair (if needed)
4. Set up equipment, start spinning.
5. Special consideration for aluminum
6. Material Requirements:Vertical and Overhead Repair Material (701-08)

Culvert Repair Details
Detail B Class A
602-3.02 (B) Structural Paving of Inverts with Concrete Class “D, H or J”
Can use Either type of concrete
• NYSDOT Item # 706-11• Materials Procedure (MP 04-001) • Pipe Diameters of 12” and up • (any size or shape can be ordered)*• *Just because you can, doesn’t mean you should
• Small construction footprint• Mostly round pipe, but not always• Bypass pumping required• Epoxy or Resin, vacuum impregnated into Felt,
Polyester or woven fiberglass • Cured by; • Steam• Hot Water• Ultra Violet
AASHTO M 252 (NYSDOT 706-13) Corrugated Polyethylene Drainage Pipe
AASHTO M 294 (NYSDOT 706-12, 14) Corrugated Polyethylene Pipe
AASHTO M 330 (NYSDOT 706-08) Polypropylene Pipe (currently for direct bury only)
AASHTO MP 20-13 (APL in process) Steel-Reinforced Polyethylene Ribbed Pipe
ASTM testing based on a pressure test
3” to 54” in diameter
Classifications by dimension ratio (DR=Do/t)
Special sizes available upon request*
Based on outside diameter
Do not bolt/anchor both ends of the liner
Cut the inlet flush with the headwall
Can use a “nose cone” for tight fits
Can place the grout tubes on the side of the liner, or inside the liner if needed.
Can usually handle a bit of scraping from the host pipe
ASTM Testing based on deflection of 3%
10” diameter up to 11 feet
Based on Inside diameter
Special sizes cannot be made
Classification by Ring Stiffness Coefficient (RSC)
Greater thickness (different wall structure) than solid wall
Cut/Grind and Rework the pipe over a tarp for easier clean up
Can be made into an “ovalized pipe” Ovalization should be secured by anchoring to a
headwall
Can bolt/anchor both ends
Do not leave the profile open
Rate is approximately 1” every 2 seconds
Depending on;
Temperature settings on the welding gun
Thickness of weld
Surrounding temperature
What are the three energy transfer medias allowed by NYSDOT for Cured In Place Pipe? (CIPP)
Hot Water
Steam
Ultra Violet
What are the two types of HDPE relining pipe? (NYSDOT Item # 706-11)
Profile Wall (ASTM F894)
Solid Wall (ASTM F714)
What are the most common mistakes made with specification 602?
Lack of complete scoping of project
Lack of adequate ROW
Remembering that excavation is NOT included in 602
Failure to understand the steps involved in the selected relining process.
