Delete in its entirety and substitute the following:

207.01 DESCRIPTION

A. The geocomposite shall consist of a geogrid heat bonded to a nonwoven geotextile for the purposes of aggregate stabilization, separation and filtration.

B. The geogrid shall be composed of a single layer and integrally formed with triangular apertures and high-profile ribs exhibiting significant dimensional stability through all ribs and junctions of the geogrid structure. The geogrid shall maintain its reinforcement and aggregate confinement capabilities under repeated dynamic loads while in service. The geogrid shall also be resistant to ultraviolet degradation, damage under normal construction practices and all forms of biological and chemical degradation normally encountered in road construction. Geogrid layers shall be placed as directed by the Engineer. The geogrid should be sized appropriately to interlock with the specified aggregate.

C. The geotextile shall be a needle-punched nonwoven geotextile made of 100% virgin polypropylene staple fibers, which are formed into a random network for dimensional stability. The geotextile must resist ultraviolet deterioration, rotting, biological degradation, naturally encountered alkalis and acids. The geotextile must be certified by the National Transportation Product Evaluation Program (NTPEP).

207.03 MATERIALS

A. The geocomposite should be lightly laminated between geogrid and geotextile to facilitate good quality interlock of aggregate. The geogrid should extend 3-6in outside the edges of geotextile to ensure interlock between aggregate and geogrid on the overlapped edge. Any geocomposites where the geotextile extends outside the edge of the geogrid will not be considered.

B. The geogrid shall be integrally formed through punching and drawing of extruded sheets of polypropylene. The geogrid shall be oriented in three substantially equilateral directions so the resulting ribs have a high degree of molecular orientation which continues at least in part through the mass of the integral node.

C. The resulting geogrid structure shall have apertures that are triangular in shape, and shall have ribs with depth-to-width ratios greater than 1.0.

D. The geocomposite shall have typical characteristics shown in the table below, and shall be certified in writing by the manufacturer to meet these characteristics.

5. Radial stiffness is determined from tensile stiffness measured in any in-plane axis from testing in accordance with ASTM D6637- 10.

6. Resistance to loss of load capacity or structural integrity when subjected to chemically aggressive environments in accordance with EPA 9090 immersion testing.

7. Resistance to loss of load capacity or structural integrity when subjected to 500 hours of ultraviolet light and aggressive weathering in accordance with ASTM D4355-05.

207.04 ALTERNATE GEOGRID MATERIAL

Alternate geogrid materials may be considered if they meet or exceed the design criteria of the project. Such materials must be pre-approved in writing by the Engineer. For alternate geogrid materials not meeting all the requirements of Section 207.03, alternate material packages must be submitted meeting or exceeding the design criteria of the project to the Engineer a minimum of 14 days prior to the bid date, and must include, as a minimum, the following:

1. Validation in writing from the authors of the design methodology (Dr. Jie Han and / or

Dr. J.P. Giroud) that the specific geosynthetic is calibrated to the Giroud – Han (G-H) equation, through the review of the manufacturer’s calculations and full-scale testing by Drs. Giroud and Han. Comparison to another geosynthetic with similar index properties that has been calibrated and validated to G-H method will not be accepted as validation to the design method, as required by the authors of the methodology.

2. Test results from full-scale wheel and / or plate load testing performed on the specific product(s) to evaluate performance, evaluating ruts between 40mm and 100mm.

3. A design signed and sealed by a professional engineer registered to practice in the state that the project is located that incorporates the performance benefits of the submitted geogrid through full-scale wheel or plate load testing based on the site specific conditions of the project.

4. Five case histories, on the specific product being supplied, that demonstrate the product performs as intended in similar applications and holds up under normal construction activities.

5. A sample of the alternate geogrid material and certified specification sheets.

Recommended installation instructions and additional information as requested by the Engineer to fully evaluate the application.

6. In-air index testing of geogrid properties, or explanations of performance based on in-air index testing of geogrid properties are not sufficient to understand the complex mechanisms involved in soil/geogrid interaction and/or the performance of MSL’s.

Therefore, no acceptance of alternates based on material property comparisons or explanations of performance based on in-air testing of geogrid properties will be allowed.

7. No performance shall be attributed to the bond between the geogrid and geotextile.

207.05 MATERIALS

A. Storage and Protection

1. Prevent excessive mud, wet concrete, epoxy or other deleterious materials from coming in contact with and affixing to the geocomposite materials.

2. Store at temperatures above -20 degrees F (-29 degrees C).

3. Rolled materials may be laid flat or stood on end.

4. Geocomposite materials should not be left directly exposed to sunlight for more than

6 months or as recommended by the manufacturer.

B. Examination

1. The Contractor shall check the geocomposite upon delivery to verify the proper material has been received. The geocomposite shall be inspected by the Contractor to be free of flaws or damage occurring during manufacturing, shipping, or handling.

207.06 EXECUTION

A. Preparation

1. The subgrade soil shall be prepared as indicated on the construction drawings or as directed by the Engineer.

B. Installation

1. The geocomposite shall be installed with the geogrid facing up.

2. The geocomposite shall be installed at the proper elevation and alignment as shown on the construction drawings.

3. The geocomposite shall be installed in accordance with these plans and specifications and any installation guidelines provided by the manufacturer or as directed by the Engineer.

4. The geocomposite may be temporarily secured in place with ties, staples, pins, sand bags or backfill as directed by the Engineer.

5. Aggregate shall be placed and compacted in accordance with the local Department of Transportation standards. Aggregate shall be placed, spread and compacted in such a manner that minimizes the development of wrinkles in the geocomposite and/or movement of the geocomposite.

6. A minimum loose aggregate thickness of 6 inches is required prior to operation of tracked vehicles over the geocomposite. Turning of tracked vehicles should be kept to a minimum to prevent tracks from displacing the aggregate base material and damaging the geocomposite. When underlying subgrade is trafficable with minimal rutting, rubber-tired equipment may pass directly over the geocomposite reinforcement at slow speeds (less than 5 mph). Sudden braking and sharp turning movements shall be avoided.

C. Inspection and Repair

1. The Owner or Owner's representative may randomly inspect geocomposite before, during and after (using test pits) installation.

2. Any damaged or defective geocomposite (i.e. frayed coating, tears, etc.) will be repaired by removal of affected area and patching using new material with a minimum three foot overlap beyond the limits of the affected area.

3. Any roll of geocomposite damaged before, during and after installation shall be replaced by the Contractor at no additional cost to the Owner.

207.07 MEASUREMENT AND PAYMENT

This work will be measured and paid for by the square yard, completed in place. No allowance will be made for overlap, splices or material cut off or wasted. Different manufacturer's overlap and splicing requirements for the intended application may vary. Payment for Earthwork Geosynthetics will include furnishing the material, labor, and equipment required to furnish, place and anchor the geocomposite, and any hand work necessary to establish grades, make geocomposite splices, and repairs to protective coatings.
