Product Type: Integrally Formed Structural Geogrid Polymer: High Density Polyethylene Load Transfer Mechanism: Positive Mechanical Interlock Recommended Applications: MESA System(Segmental Block Wails),SierraScape System(Welded Wire Walls) Product Properties Index Properties Units MD Values • Tensile Strength @ 5%Strain2 kN/m(lb/ft) 27(1,850) • Ultimate Tensile Strength2 kN/m(lb/ft) 58(3,970) • • Junction Strength3 kN/m(Ib/ft) 54(3,690) • Flexural Stiffness'/ mg-cm 500,000 Durability • Resistance to Long Term Degradation5 % 100 • Resistance to UV Degradations % 95 Load Capacity • Maximum Allowable Strength for 120-year Design Life7 kN/m(Ib/ft) 21.2(1,450) Recommended Allowable Strength Reduction Factors? • Minimum Reduction Factor for Installation Damage(RF1D)8 1.05 • Reduction Factor for Creep for 120-year Design Life(RFcR)9 2.60 • Minimum Reduction Factor for Durability(RFD) 1.00 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 76.2 meters(250.0 feet)in length: A typical truckload quantity is 432 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. 2.True resistance to elongation when initially subjected to a load measured via ASTM D6637-10 Method A 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 ASTM D7737-11. 4.Resistance to bending force determined in accordance with ASTM D7748-12,using one meter(minimum)long specimen. 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(Tali)by reduction factors for installation damage(RFI0),creep(RFcR)and chemical/biological durability(RFD=RFco•RFBo)per GRI-GG4-05[Tam(=Tuli/(RFID•RFcR•RFD)j.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. Tensar International Corporation warrants that at the time of delivery the geogrid This product specification supersedes all prior specifications for the product described furnished hereunder shall conform to the specification stated herein. Any other above and is not applicable to any products shipped prior to February 1,2013. warranty including merchantability and fitness fora particular purpose,are hereby excluded.If the geogrid does not meet the specifications on this page and Tensar is notified prior to installation,Tensar will replace the geogrid at no cost to the customer.
