985-1 Description .
Geosynthetic materials are used for nonstructural and structural applications and shall be either geotextiles (woven or non -woven) or geogrids (woven or extruded) that are used for drainage, erosion control, r einforcement, separation or stabilization .
985-2 General Requirements .
985-2.1 Product Acceptance : All geosynthetic materia ls shall be one of the products
listed on the Department’s Approved Product List (APL). Manufacturers seeking evaluation of products for inclusion on the APL shall submit an application in accordance with Section 6 and include the following documentation. A separate application must be submitted for each geotextile type to be evaluated, showing that the product meets the applicable requirements. Documentation Requirements Installation Instructions Include surface preparations, installation, overlap or sewing instructions, and repair procedures. NTPEP Audit Report, for Structural Geosynthetic Materials Only manufacturer’s facility included on NTPEP’s list of compliant producers. NTPEP Test Results Product meets requirements of this Section Product Label Photo Displays the Product Name Product Photo Displays the significant features of the product as required in this section. Displays location of Manufacturer name and model number. Technical Data Sheet Uniquely identifies the product and includes product specifications , reporting requirements, and storage instructions Products will be listed on the APL according to the geosynthetic application type.
985-2.2 Material Application : In addition to the general requirements, meet the
following physical requirements: Drainage ................................ ................................ .............................. 985-3 Erosion Control ................................ ................................ ................... 985-4 Structural ................................ ................................ ............................. 985-5
985-2.3 Materials : The geosynthetic material shall be a woven , non-woven or extruded
material consisting of long -chain polymeric filaments or yarns such as polypropylene, polyethylene, polyester, polyamides or polyvinylidene chloride formed into a stable network such that the filaments or yarns retain their relative position to each other. The bas e plastic shall contain stabilizers and/or inhibitors to make the filaments resistant to deterioration due to ultra - violet light, heat exposure and potential chemically damaging environment . The edges of the material shall be selvaged or otherwise finished to prevent the outer yarn from pulling away from the material and shall be free of any treatment which may significantly alter its physical properties.
985-2.4 Physical Requirements : Each geosynthetic material shall be tested by an
independent third par ty in accordance with the methods shown. All testing and reported values, FY 2023-24 Return to Table of Contents
