Geogrid shall be Tensar UX1800 HS or equivalent and shall have the following properties: <br />TABLE 2.01 <br />TYPICAL GEOGRID PROPERTIES <br />Notes: <br />1. <br />amec <br />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 />Section 02776.1 <br />Geogrid <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 />S: \Protects \1125E CCV CQA \I - Tech Specs \02776 1r1 doc <br />a.
