Section 207 – EARTHWORK GEOTEXTILES

Delete the text of this Section and substitute the following:

Description

207.01 This work consists of furnishing and placing geotextile as a permeable separator, stabilizer, or permanent erosion control measure.

This work also consists of furnishing and placing geogrid as a soil reinforcement element.

Geotextile types are designated as shown in Subsection 714.01.

Material

207.02 Conform to the following Subsection:

Geotextile 714.01

Geogrid 714.01

Construction Requirements

207.03 General. Submit test results to the CO verifying the proposed products meet the criteria as outlined in Section 714.

Where placing a geotextile on native ground, cut the trees and shrubs flush with the ground surface. Do not remove the topsoil and vegetation mat. Remove all sharp objects and large rocks. Fill depressions or holes with suitable material to provide a firm foundation.

Replace or repair all geotextile or geogrid that is torn, punctured, or muddy. Remove damaged area and place a patch of the same type of material by overlapping 3 feet beyond the damaged area.

Furnish geogrid packaged in a sheathing or container suitable to protect the geogrid from damage due to ultraviolet light during storage and handling. Store, handle, and haul all the materials in accordance with the manufacturer’s specifications and as directed by the CO. Furnish geogrid that is visibly labeled with the name of the manufacturer, identification of the geogrid product, date of manufacture, lot number, length, width, and quantity.

207.04 Separation and Stabilization Applications. Where placing a geotextile on a subgrade, prepare the subgrade according to Subsection 204.13(c) and (d).

Place the geotextile smooth and free of tension, stress, or wrinkles. Fold or cut the geotextile to conform to curves. Overlap in the direction of construction. Overlap the geotextile a minimum of 2 feet at the ends and sides of adjoining sheets, or sew the geotextile joints according to the manufacturer’s recommendations. Do not place longitudinal overlaps below anticipated wheel loads. Hold the geotextile in place with pins, staples, or piles of cover material.

23 | P a g e

End dump the cover material onto the geotextile from the edge of the geotextile or from previously placed cover material. Do not operate equipment directly on the geotextile. Spread the end-dumped pile of cover material maintaining a minimum lift thickness of 12 inches.

Compact the cover material with rubber tired or non-vibratory smooth drum rollers. Avoid sudden stops, starts, or turns of the construction equipment. Fill all ruts from the construction equipment with additional cover material. Do not regrade ruts with placement equipment.

Place subsequent lifts of cover material in the same manner. Vibratory compactors may be used for compacting subsequent lifts. If foundation failures occur, repair the damaged areas and revert to the use of non-vibratory compaction equipment.

207.05 Permanent Erosion Control Applications. Place and anchor the geotextile on an approved smooth-graded surface. For slope or wave protection, place the long dimension of the geotextile down the slope. For stream bank protection, place the long dimension of the geotextile parallel to the centerline of the channel.

Overlap the geotextile a minimum of 12 inches at the ends and sides of adjoining sheets or sew the material according to manufacturer’s recommendations. Overlap the uphill or upstream sheet over the downhill or downstream sheet. Offset end joints of adjacent sheets a minimum of 5 feet. Pins may be used to hold geotextile sheets in place. Space pins along the overlaps at approximately 3-foot centers.

Place aggregate, slope protection, or riprap on the geotextile starting at the toe of the slope and proceed upward. Place riprap onto the geotextile from a height of less than 12 inches. Place slope protection rock or aggregate backfill onto the geotextile and cover material in the same day.

207.06 Soil Reinforcement Applications. Install the geogrid reinforcement according to the manufacturer’s recommendations. Place the geogrid reinforcement at the elevations and to the extent shown on the plans. Place the geogrid reinforcement in continuous longitudinal strips such that the principle strength (highest strength) axis is perpendicular to the slope or wall face.

If unable to complete the required length with a single continuous length of geogrid, a joint may be made with the approval of the CO. Only one joint per length of geogrid will be allowed.

Construct this joint for the full width of the strip using a similar material, conforming to the requirements of Subsection 714.03(a), and follow the manufacturer’s recommendations. Pull and hold taut joints in geogrid reinforcement prior to backfilling. After a layer of geogrid reinforcement has been placed, use suitable means, such as pins or small piles of soil, to hold the geogrid reinforcement in position until the subsequent layer of backfill can be placed. Do not operate track-mounted equipment on the geogrid reinforcement until at least 6 inches of soil has been placed over the geogrid. Keep equipment turning to a minimum to prevent displacement of embankment and damage to the geogrid material. If approved by the CO, rubber tired equipment may pass over the geogrid reinforcement at speeds less than 10 miles per hour. If during embankment placement waves, wrinkles, or slack develop in the geogrid, remove the embankment and pull the geogrid taut to remove slack.

Place only the amount of geogrid reinforcement required for immediately pending work to prevent undue damage. During construction, the surface of the fill should be kept approximately horizontal. Place geogrid reinforcements within 3 inches of the design elevations and extend to

24 | P a g e the length shown in the plans unless otherwise directed by the CO. Place uniaxle (primary) and biaxle (secondary) geogrid reinforcement as show on the plans or as directed by the CO. Place and compact embankment soils according to Subsections 204.10 and 204.11. Do not place sharp or angular rock and rock larger than 4 inches in diameter with 6 inches of the geogrid reinforcement. After the specified soil layer has been placed, install the next layer of geogrid reinforcement. Repeat the process for each subsequent layer until final grade is reached.

207.07 Acceptance. Material for earth work geotextile will be evaluated under Subsections 106.02, 106.03, and 714.01. Material for geogrid will be evaluated under Subsections 106.02, 106.03, and 724.03.

Earthwork geotextiles installation will be evaluated under Subsections 106.02 and 106.04.

Measurement

207.08 Measure the Section 207 items listed in the bid schedule according to Subsection 109.02 and the following as applicable.

Payment

207.09 The accepted quantities will be paid at the contract price per unit of measurement for the Section 207 pay item listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.
