Section 260 - Geocell Abutment Stabilization

Description

260.01 Work. Construct geocell abutment stabilization at each abutment using Presto Geoweb Cellular Confinement System, Webtec TerraCell, or approved equal in accordance with the plans and manufacturers recommendations.

Materials

260.02 Requirements. Ensure that material conforms to specifications in the following subsections:

Coarse Granular Backfill 703.03 Geocell 726 Geotextile, Type IV (A,B,C.D,E, or F) 714.01

Construction

260.03 General. Perform the work specified in Section 206. Use ditches, grading or similar methods to prevent surface runoff that may occur during inclement weather from ponding in the foundation excavation.

260.04 Geotextile Installation. Place the geotextile according to Section 221 or AS SHOWN ON THE DRAWINGS. Ensure that the surface upon which the geotextile is to be placed is uniform and is reasonably smooth and free of obstructions, depressions, and debris that could damage the geotextile .

Have the surface approved by the CO prior to placing geotextile.

Lay the geotextile without tension, stress, wrinkles or creases. Sew or overlap adjacent strips a minimum of 12” at joints. Insert securing pins through both strips of overlapped geotextile at minimum intervals of 3 feet, but no closer than 2 inches to each edge, to prevent the geotextile from being displaced.

Have the installed geotextile approved by the CO prior to setting the geocells.

260.05 Geocell Installation. Place the geocell sections directly on the prepared subgrade. Expand the geocell sections into position at the grades and lines AS SHOWN ON THE DRAWINGS. Hold the expanded geocell sections with suitable “stretcher frames”, steel stakes driven inside selected outer cell walls, or other similar methods as allowed by the geocell manufacturer prior to filling. Ensure that the individual cells have been expanded to the minimum dimensions required by the manufacturer. If necessary field cut sections as per the manufacturer’s recommendations to the lines SHOWN ON THE

PLANS.

Connect geocell panels in accordance with the manufacturer’s recommendations.

260.06 Infill Placement. Furnish the CO with the manufacturer’s specific recommendations for backfilling prior to placement of the geocells.

Place coarse granular backfill meeting subsection 703.03 into the expanded cells with equipment appropriate for the site conditions such as a backhoe or a front-end loader. Do not drop infill material more than 3 feet to avoid damage or displacement of the cell walls.

Overfill the geocell cells and level to a minimum of 2 inches above the top of the cell walls. A front-end loader may be used to place the infill provided that it only traffics above geocell sections that have been filled and covered with the minimum 2 inches of additional material. Compact the infill material with a vibratory plate compacter. Operate compaction equipment over the full width of the geocell until visible deformation of the infill ceases. Make at least three complete passes. Grade the surface to be ½ inch above the top of the cells . Ensure that the cell walls are not exposed after fine grading is completed.

Use the geocell manufacturer’s specific recommendations for backfilling if they are more stringent than stated above.

Measurement

260.07 Method. Use the method of measurement that is DESIGNATED IN THE SCHEDULE OF

ITEMS.

Payment will be based on the contract unit price of geocell material placed and accepted. This will be exclusive of wastage and material placed outside the neat lines SHOWN ON THE PLANS.

Payment

260.08 Basis. The accepted quantities will be paid for at the contract unit price for the PAY ITEM

DESIGNATED IN THE SCHEDULE OF ITEMS.

The cost for furnishing and placing the Coarse Granular Backfill required for geocell infill is incidental to this pay item and no separate payment will be made.

The cost for furnishing and placing geotextile for the geocell installation is incidental to this pay item and no separate payment will be made.

Payment will be made under:

Pay Item Pay Unit

260 (01) Geocell abutment stabilization, __inch depth Square Yard

Section 726 - Geocell

Furnish geocell panels consisting of sheet strips fabricated from high-density polyethylene (H.D.P.E.).

which are connected in series at off-set, full-depth ultrasonic seams, aligned perpendicular to the longitudinal axis of the strips. When expanded, the interconnected strips form the walls of a flexible, three-dimensional cellular confinement structure into which the specified infill materials can be placed.

Ensure that the polyethylene material used to fabricate the geocell sections is treated to resist ultraviolet degradation and that it conforms to the following:

(a) Density ………………………… 0.935-0.965 g/cm3 per ASTM D1505

(b) Environmental Stress

Crack Resistance (ESCR) ……… 2000 hour per ASTM D1693

Use strips with a sheet thickness, of 1.27 mm -5% +10% (50 mil -5% +10%) tested per ASTM D5199.

Thickness shall be determined in the flat, before any surface texturing or other surface disruption.

Ensure that cell seam strength is uniform over the full depth of the cell. Test short-term peel strength per U.S. Army Corps of Engineers Technical Report GL-86-19, Appendix A. Provide a minimum seam peel strength of 2000 N (450 lb) for the 203 mm (8.0 in) depth cell.

Test seam hang-strength for a period of 30 days minimum at room temperature. Room temperature is defined in ASTM E41. Use test samples made by welding two 102 mm (4 in) wide polyethylene strips together. Ensure that a test sample consisting of two carbon black stabilized strips supports a 72.5 kg (160

lb) load for the test period and that a test sample consisting of carbon black stabilized strip and a HALS stabilized strip supports a 63.5 kg (140 lb) load for the test period.

Furnish the CO with a certificate signed by a legally authorized official from the company that manufactured the geocell. Ensure that the certificate attests that the geocell meets the chemical, physical, material and manufacturing requirements stated in the specification. When requested by the CO, furnish a sample of the geocell from each lot for verification testing.

During shipment and storage, wrap the geocell in heavy-duty protective covering. Protect the geocell from mud, soil, dust, debris and sunlight prior to installation.
