PART 2: PRODUCTS <br />2.01 MATERIALS <br />A. Geogrid shall be Tensar UX1800 HS or equivalent and shall have the following properties: <br />TABLE 2.01 <br />TYPICAL GEOGRID PROPERTIES <br />PROPERTY <br />TEST METHOD <br />UNITS <br />VALUE <br />Reinforcement <br />- flexural rigidity <br />- tensile strength <br />ASTM D5732 -95 <br />ASTM D6637 <br />mg -cm <br />9,500,000 (min) <br />at 5% strain <br />6,500 (min) <br />at ultimate <br />14,300 (min) <br />- junctions <br />GRI GG2 -87 <br />lb /ft <br />strength <br />12,340 (min) <br />Material <br />- high density polyethylene <br />ASTM D 1248 <br />% <br />97 (min) <br />Type HI/Class At Grade 5 <br />- carbon black <br />ASTM 4218 1 <br />% <br />2.0 (min) <br />Notes: <br />1. Resistance to bending force determined in accordance with ASTM D5732 -95, using specimen dimensions <br />of 864 millimeters in length by one aperture in width. <br />2. True resistance to elongation when initially subjected to a load via ASTM D6637 without deforming test <br />materials under load before measuring such resistance or employing "secant' or `offset' tangent methods of <br />measurement so as to overstate tensile properties. <br />3. Geogrid junction strength and junction efficiency measured by Geosynthetic Research Institute test method <br />GG2 -87 " Geogrid Junction Strength." <br />B. Geogrid shall be capable of retaining its structure during handling, placement, and long -term service. <br />2.02 MANUFACTURER QUALITY CONTROL <br />CONTRACTOR shall ensure that geogrid MANUFACTURER meets the conditions in this section. <br />A. Geogrid Tests and Inspection <br />1. Geogrid MANUFACTURER shall perform quality control testing of the geogrid. Samples <br />not satisfying specifications shall result in the rejection of applicable rolls. At a minimum, <br />the following tests shall be performed for quality control in accordance with test methods <br />specified in Table 2.01. <br />a. Density <br />b.
