HIGH SURVIVABILITY FILTER FABRIC Geotextile fabric underlay specification from ADOT Standard Specifications for Road and Bridge Construction 2008 SECTION 913 BANK PROTECTION: 913-2.05 Bank Protection Fabric: Fabric shall be supplied in accordance with and conform to the material requirements of Subsections 1014-1 and 1014-5, respectively. Special attention shall be given to the required survivability of the fabric. The identification, packaging, handling, and storage of the geotextile fabric shall be in accordance with ASTM D 4873. Fabric rolls shall be furnished with suitable wrapping for protect ion against moisture and extended ultraviolet exposure prior to placement. Each roll shall be labeled or tagged to provide product identification sufficient to determine the product type, manufacturer, quantity, lot number, roll number, date of manufacture, shipping date, and the project number and name to which it is assigned. Rolls will be stored on the site or at another identified storage location in a manner which protects them from the elements. If stored outdoors, they shall be elevated and protected with a waterproof, light colored, opaque cover. At no time, shall the fabric be exposed to sunlight for a period exceeding 14 days. SECTION 1014 GEOSYNTHETICS: 1014-1 General Requirements: Certificates of Compliance, conforming to the requirements of Subsection 106.05, shall be submit ted to the Engineer by the contractor upon delivery of geosynthetic materials for use on a specific project. If the delivered materials have not been evaluated and preapproved as noted below, it will be necessary for a Certificate of Analysis to be submit ted to the Engineer along with the supporting documentation before the material may be considered for use on the project. Each geosynthetic material lot or shipment must be approved by the Engineer before the materials may be incorporated in the work. Certificates of Analysis, conforming to the requirements of Subsection 106.05, may be submit ted, along with a representative sample of appropriate size for testing, by the supplier or manufacturer of any geosynthetic material to ADOT Materials Group for evaluation and preapproval. Testing methods and results shown in the Certificate of Analysis shall conform to the listed specifications for the proposed geosynthetic use. Supporting documentation including, but not limited to, product information sheets, installation procedures and recommendations, recommended use, and project references shall also be submit ted by the supplier or manufacturer as part of product evaluation and preapproval. Geosynthetic materials shall be furnished in protective covers capable of protecting the materials from harmful environmental conditions such as ultraviolet rays, abrasion, extreme heat, and water. Storage of the materials will be in a manner to prevent damage, contamination, or deterioration of the materials. Samples of geosynthetic materials shall be submitted for testing. No samples shall be taken within five feet of either end of a roll. Samples shall be a minimum of three feet long by the full
roll width. A minimum of one sample shall be taken per lot. More samples may be required as determined by the Engineer. 1014-4 Separation Geotextile Fabric: Separation geotextile fabric shall be a non-woven or woven fabric consisting only of long chain polymeric filaments such as polypropylene or polyester formed or woven into a stable network such that the filaments retain their relative position to each other. The fabric shall be inert to commonly encountered chemicals, resistant to rot and mildew, and shall have no tears or defects which adversely affect or alter its physical properties. The physical requirements for the separation fabric will be determined by the survivability rating called out for the fabric in the Special Provisions or as shown on the project plans. Physical requirements for nonwoven or woven fabrics for each survivability rating are listed in Subsections 1014-4.01, 1014-4.02, 10144.03, and 1014-4.04. 1014-4.03 High Survivability Fabric: (A) Nonwoven: High survivability, nonwoven separation fabric shall meet the following minimum average roll values: Property: Requirement (Test Method) Grab Tensile Strength, lbs.: 200 (ASTM D 4632) Grab Elongation at Break, %: 45 min., 115 max.
