Geogrid shall be Tensar UX1800 HS or equivalent and shall have the following properties: <br />TABLE 2.01 <br />TYPICAL GEOGRID PROPERTIES <br />• <br />PROPERTY TEST METHOD UNITS VALUE <br />Reinforcement <br />- flexural rigidity ASTM D5732-951 mg-cm 9,500,000 (min) <br />- tensile strength ASTM D66372 <br />at 5% strain 6,500 (min) <br />at ultimate 14,300 (min) <br />- junctions GRI GG2-873 lb/ft <br />strength 12,340 (min) <br />Material <br />- high density polyethylene ASTM D 1248 % 97 (min) <br /> Type HI/Class Al Grade 5 <br />- carbon black ASTM 4218 % 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. Mass per unit area <br />• c.
