PART 2: PRODUCTS

2.1 PHYSICAL AND CHEMICAL REQUIREMENTS

A. Assure that fibers used in the manufacture of geotextiles, and the threads used in joining geotextiles by sewing, consist of long-chain synthetic polymers, composed of at least 95% by weight polyolefins, polyesters, or polyamides. They must be formed into a network so the filaments on yarns retain dimensional stability relative to each other, including selvedges. Furnish materials meeting the physical requirements for the indicated application as described by the corresponding table(s) of properties in ASSHTO M288, Geotextile Specifications for Highway Applications.

2.2 CERTIFICATION

A. Assure the manufacturer furnishes the purchaser a certificate stating the name of the manufacturer, the chemical composition of the filaments or yarns, and other information fully describing the geotextile. The manufacturer must include in the certificate a guarantee stating that the geotextile furnished meets specifications.

The certificate must be attested to by a person having legal authority to bind the company. Mismarking or misrepresentation by the manufacturer is reason to reject the geotextile under these specifications. Notice sent to the manufacturer by the purchaser regarding rejection of, will be considered to be notice to all

PRICE ROAD 2021 02110 - 3

wholesalers, jobbers, distributors, agents and other intermediaries handling the manufacturer’s product.

B. Label the fabric and its container with the manufacturer’s name and fabric type or trade name, lot number and quantity.

2.3 SHIPMENT AND STORAGE

A. During shipment and storage, protect the fabric from direct sunlight, ultra-violet rays, temperatures exceeding 140°F, mud, dust and debris. Keep the fabric in the manufacturer’s wrapping until just before use. Include in each shipping document a certification that the geotextile meets the manufacturer’s certificate and guarantee previously filed with the purchaser.

2.4 MANUFACTURER’S

A. Separation/stabilization fabric for placement between native subgrade and sub base or base course shall be a woven polypropylene geotextile such as Propex Geotex 250ST or equal.

3.1 GENERAL

A. Where placing geotextiles on native ground, remove all sharp objects and large rocks. Fill depressions or holes with a suitable material to provide a firm foundation.

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

3.2 DRAINAGE, SEPARATION AND STABILIZATION APPLICATIONS

A. Shape the subgrade to a smooth surface and to the cross section required. Shape slopes to gradually transition into slope adjustments without noticeable breaks.

At the ends of cuts at the intersection of cuts and embankments, adjust slopes in the horizontal and vertical planes to blend into each other or into the natural ground.

B. Remove all material larger than 3 inches within the top 6 inches of the roadbed.

Remove unsuitable material from the roadbed and replace with suitable material.

Finish the roadbed and ditches to the required elevation and cross-section.

C. Place the geotextile smooth and free of tension, stress, or wrinkles. Fold and cut the geotextile to conform to curves. Overlap in the direction of construction.

PRICE ROAD 2021 02110 - 5

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.

D. 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 8 inches. Compact the cover material with rubber-tired or nonvibratory smooth drum rollers. Avoid sudden stops, starts, or turns of the construction equipment. Fill all ruts from construction equipment with additional cover material. Do not regrade ruts with placement equipment.

E. 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 nonvibratory compaction equipment.

3.3 TEMPORARY AND PERMANENT EROSION CONTROL APPLICATIONS

A. Place and anchor the geotextile on the approved smooth-graded surface. For slope 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.

B. Overlap the geotextile a minimum of 12 inches at the ends and sides of adjoining sheets or sew the geotextile joints according to the 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 the geotextile sheets in place. Space pins along the overlaps at approximately 3-foot centers.

C. 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 from a height less than 3 feet. In underwater applications, place the geotextile and cover material in the same day.

PART 4: MEASUREMENT AND PAYMENT

4.1 Measurement

PRICE ROAD 2021 02110 - 6

A. All geotextiles will be measured by the square yard of surface covered on a plane parallel to the ground surface, excluding overlaps (no allowance is made for additional fabric required for overlap joints).

4.2 Payment

A. The accepted quantities, measured as provided above, will be paid at the contract price per unit of measurement for the pay item that is shown in the bid schedule.

Payment will be full compensation for the work described in this Section, including materials, labor, equipment, tools and incidental items. Payment is made under:

PART 1 - GENERAL

1.1 SECTION INCLUDES

A. This Section includes all site clearing, excavating, placing, filling, backfilling, borrow material, topsoil stripping and salvage, compacting and grading as shown on the drawings and specified herein, including the following;

1. Provide horizontal and vertical control staking.

2. Provide borrow material, topsoil stripping and salvage, excavation, rough grading, subgrade preparation, filling, backfilling, compaction, fine grading and disposal of spoil material as shown on the drawings to meet line and grade specified herein, or as specified to complete the Work.

3. Material excavated shall be defined as “unclassified excavation” and shall include all excavation performed under this item regardless of the material encountered, except for contaminated material requiring special handling and disposal.

4. The Government estimates 10,567 cubic yards for Topsoil Stripping, Stockpiling and Re-spreading as measured by survey neat-line in place before any work, no shrink/swell factors have been applied. 17,642 cubic yards for Embankment in

Place +18%. Federal Acquisition Regulation (FAR) 52.236-16 Alternate 1, Quantity Surveys applies to this section.

This +18% accounts for the fact that excavated material will shrink below the excavated volume when compacted into the fill. The value is calculated as follows: 1.18*((Final Surface – Existing Surface) – Aggregate QTY)
