Prior to haul, the Contractor shall submit certified test results from an accredited testing laboratory that the aggregate surface material to be furnished for this project has a non-detect result when analyzed by either a combination of scanning electronic microscope (SEM) and energy dispersive x-ray spectroscopy (EDS) or SEM and x-ray diffraction (XRD). Samples tested must be representative of the material proposed for this project. Test results shall include a copy the sampling plan and a copy of the chain of custody for the sample.

At a minimum the sampling plan shall include the source location including GPS coordinates; the name and contact information for the person collecting the sample; a sketch showing specific sample locations; photographs of actual sample locations; the sampling equipment and method;

and the depths below grade before adding to the composite sample.

272.04 Storage and Handling of Material. During shipment and storage, wrap geotextile materials in heavy-duty protective covering. Protect the material from mud, soil, dust, debris and sunlight prior to installation.

272.05 Geotextile Installation. Place the geotextile according to Section 207. Have the surface approved by the COR prior to placing geotextile.

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 COR prior to setting the geocells.

272.06 Geocell Installation. Furnish the COR with product literature and certification as required in Section

106.03 for review and approval 7 days prior to installation. When requested by the COR, furnish a sample of the geocell from each lot for verification testing.

Place the geocell sections directly on the prepared subgrade. Expand the geocell sections into position at the grades and lines as shown on the plans. 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 manufacturer prior to filling. Ensure that the individual cells have 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.

272.07 Infill Placement. Furnish the COR with the manufacturer’s specific recommendations for backfilling 7 days 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. Make at least three complete passes or until visible deformation of the infill ceases. 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.
