Dimensions and Delivery
The structural geogrid shall be delivered to the jobsite in roll form with each roll individually identified and nominally measuring 1.33
meters (4.36 feet) in width and 61.0 meters (200.0 feet) in length. A typical truckload quantity is 144 rolls.
Notes:
1. Unless indicated otherwise, values shown are minimum average roll values determined in accordance with ASTM D4759 -02. Brief descriptions
of test procedures are given in the following notes. Complete descriptions of test procedures are available on request from Tensar International
Corporation.
2. True resistance to elongation when initially subjected to a load measured via ASTM D6637 -01 without deforming test materials under load before
measuring such resistance or employing "secant" or "offset" tangent methods of measurement so as to overstate tensile properties.
3. Load transfer capability determined in accordance with GRI- GG2 -05.
4. Resistance to bending force determined in accordance with ASTM D5732 -01, using specimen dimensions of 864 millimeters in length by one
aperture in width.
5. Resistance to loss of load capacity or structural integrity when subjected to chemically aggressive environments in accordance with EPA 9090
immersion testing.
6. 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.
7. Reduction factors are used to calculate the geogrid strength available for resisting force in long -term load bearing applications. Allowable
Strength (Tallow) is determined by reducing the ultimate tensile strength (T by reduction factors for installation damage (RFID), creep (RFcR) and
chemical /biological durability (RFD = RFCD•RFBO) per GRI- GG4 -05 [Tallow = T /(RFID•RFcR•RFD)]. Recommended minimum reduction factors are
based on product - specific testing. Project specifications, standard public agency specifications and /or design code requirements may require
higher reduction factors. Design of the structure in which the geogrid is used, including the selection of appropriate reduction factors and design
life, is the responsibility of the outside licensed professional engineer providing the sealed drawings for the project.
8. Minimum value is based on Installation Damage Testing in Sand, Silt, and Clay soils. Coarser soils require increased RFID values.
9. Reduction Factor for Creep determined for 120 -year design life and in -soil temperature of 20 °C using standard extrapolation techniques to creep
• rupture data obtained following the test procedure in ASTM D5262 -04. Actual design life of the completed structure may differ.
