SECTION 33420

CULVERTS

1.1 This work consists of constructing culverts and culvert extensions.

PART 2- MATERIALS

2.1 Corrugated Polyethylene Pipe (CPP): Furnish nonperforated corrugated polyethylene pipe conforming to AASHTO M 294. For watertight joints, conform to ASTM D 3212. Pipe diameter to be as shown on the Plans. Furnish culvert pipe with a wall thickness not less than that required by ASTM F667 – 12.

2.2 Foundation Fill. In accordance with FP – 03 Subsection 704.01.

2.3 Bedding Material. In accordance with FP – 03 Subsection 704.02.

2.4 Backfill Material. In accordance with FP – 03 Subsection 704.03(b).

PART 3- CONSTRUCTION

3.1 General. Use the same material and coating on all contiguous pipe sections and special sections such as elbows and branch connections. For culvert extensions, furnish the same material as the existing culvert.

The plans show the size, approximate location, and length of culverts. Determine final location, skew, length, elevations, and grade according to the following:

Stake culverts to fit field conditions. The location of culverts may differ from the plans. Perform the following:

1. Survey and record the ground profile along the culvert centerline.

2. Determine the slope catch points at the inlet and outlet.

3. Set reference points and recorded information necessary to determine culvert length and end treatments.

4. When the field design has been approved, set drainage structure survey stakes, reference stakes, and stake inlet and outlet ditches to make the structure functional.

5. Stake or grade ditches to make the culvert functional.

6. Reset stakes as many times as necessary to construct the work.

Do not order culvert material until obtaining acceptance of the final structure size, length, and alignment.

3.2 Preparation for Structure Excavation. Clear the area of vegetation and obstructions according to FP – 03 Subsections 201 and 203.

3.3 Excavation. Excavate according to FP – 03 Subsection 208.04. Excavate to foundation grade without unduly disturbing the trench surface. Foundation grade is the elevation at the bottom of any bedding for installing the structure. Compact the foundation.

3.4 Channel Preservation. Preserve channels according to FP – 03 Subsection 208.05 except excavate inside separations such as dikes or sandbags.

3.5 Dewatering. Where necessary to dewater, dewater according to FP – 03 Subsection 208.08.

3.6 Foundation Preparation. Excavate any unsuitable material present at foundation grade, and replace it with foundation fill. Place and compact foundation fill material according to Subsection 208.09(d)

3.7 Bedding. Level the foundation. Place un-compacted bedding material over the foundation in a layer of uniform thickness. For pipe with diameters of 12 to 54 inches, the bedding thickness is 4 inches. For pipe diameters larger than 54 inches, the bedding thickness is 6 inches. For belled joints, recess the bedding to receive the joints. Place the culvert on un-compacted bedding layer.

3.8 Laying Plastic Pipe. Ensure that the final installed alignment of all pipe allows no reverse grades, and does not permit horizontal and vertical alignments to vary from a straight line drawn from center of inlet to center of outlet by more than 2 percent of pipe center length or 1.0 feet, whichever is less.

Lay plastic pipe according to the pipe manufacturer’s recommendation. Provide soil-tight and spigot joints for plastic pipe culverts. If plastic end sections are used, reinforce and stiffen them such that inward buckling during construction is less than 3/8 inch with 100 lbs of force

3.9 Backfill. Bring backfill up evenly on all sides of the structure, and extend each layer to the limits of the excavation or to natural ground. Place and compact material in evenly balanced layers on each side of each pipe culvert. Place and compact backfill to a height of 12 inches above the top of the pipe. Complete the backfilling of the trench with suitable roadway excavation or unclassified borrow.

Place material in layers that, when compacted, do not exceed 6 inches in thickness. Compact each layer according to FP – 03 Subsection 209.11.

3.10 Compacting. Compact backfill using designated compaction method A:

Method A. Ensure that backfill density exceeds the density of the surrounding embankment.
