Product Specification - Structural Geogrid UX800HS Tensar Earth Technologies,inc.reserves the right to change its product specifications at anytime. It is the ensure that product specifications used for design and procurement with the odd of the d in each and purchaser to Purposes are current and consistent with the products used In each fnsta contact Tensar Earth Technologies,ink.at 800-836-7271 for assistance nce. Please The structural geogrid shall be an integrally formed grid structure manufactured of a stress resistant polypropylene material with molecular weight and molecular characteristics which impart:(a)high resistance to loss of load capacity or structural integrity when the geogrid is subjected to mechanical stress in installation;(b)high resistance to deformation when the geogrid is subjected to applied force in use;and (c)high resistance to loss of load capacity or structural integrity when the geogrid is subjected to long-term environmental stress. The structural geogrid shall accept applied force in use by positive mechanical interlock(i.e.by direct mechanical keying)with:(a) compacted soil or construction fill materials;(b)contiguous sections of itself when overlapped and embedded in compacted soil or construction fill materials;and(c)rigid mechanical connectors such as bodkins,pins or hooks.The structurat geogrid shall possess sufficient cross sectional profile to present a substantial abutment interface to compacted soil or particulate construction flit materials and to resist movement relative to such materials when subject to appried force. The structural geogrid shall possess sufficient true initial lied force to be transferred to the geogrid at low strain levels without material deformation of the reinforced structure. modulus to cause app The structural geogrid shall possess complete continuity of all properties throughout its structure and shag be suitable for reinforcement of compacted soil or particulate construction fill materials to improve their long term stability in structural load bearing applications such as earth retention systems. The structural geogrid shall otherwise have the following characteristics: Product Type: Integrally Formed Structural Geogrid Load Transfer Mechanism: Positive Mechanical Interlock Product Properties Load Capacity Units MD Values • True initial Modulus in Use Mm(lb✓ft) 800(54,830) • Tensile Strength @5%Strain kN/m(Ib/ft) 25(1,710) • Ultimate Tensile Strength2 kN/m(It>/ft) 50(3,430) • Long-Term Allowable Load in Sands.Silts&Clay3 kN/m b/ft ) 12.5(860) • Long-Term Allowable Load in Weil Graded Sandi kN/m(tb/ft) 12.2 830 • Long-Term Allowable Load in Aggregate3 kN/m t ( ) (b/ft) 12.0(820) integrity of Product Structure • Junction Strength° kN/m(lb/ft) 47(3,180) • Flexural Stiffnesss X1000 mg-cm 500 Durability • Resistance to installation Damageii %SC/%SW/%GP • Resistance to Long Term Degradations • 95/92/90 � 100 Dimensions and Delivery The structural geogrid shalt 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 324 rolls. On special request,the structural geogrid may also be custom cut to specific lengths or widths to suit site specific engineering designs. Notes 1.Unless indicated otherwise,values shown are minimum average.roil values determined in accordance with ASTM D-4759grief descriptions of test procedures are given in the following notes. Complete descriptions of test procedures are available on request from Tensar Earth Technologies, Inc. 2.True resistance to elongation when initially subjected to a bad measured via ASTM D6637 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.True strength available for resisting force in brig-term load bearing applications is determined by reducing ultimate tensile strength by state-of- practice factors for installation damage,degradation in use,product integrity limitations and long-term product deformation per GRI-GG4. 4.Load transfer capability measured via GRI-GG2-87. 5.Resistance to bending force measured via ASTM D-5732-95,using specimen dimensions of 864 millimeters in length by 1 aperture in width. 6.Resistance to loss of load capacity or structural integrity when subjected to mechanical installation stress in clayey sand(SC),well graded sand (SW),and crushed stone classified as poorly graded gravel(GP).The material shalt be sampled in ac.cordance with ASTM D5818 and load capacity measured in accordance with ASTM D6637. 7.Resistance to lass of load capacity or structural integrity when subjected to chemically aggressive environments measured via EPA 9090 immersion testing.
