ameO <br /> PART 2: PRODUCTS <br /> 2.01 MATERIALS <br /> A. Geogrid shall be Tensar UX 1800 HS or equivalent and shall have the following properties: <br /> TABLE 2.01 <br /> TYPICAL GEOGRID PROPERTIES <br /> PROPERTY TEST METHOD UNITS VALUE <br /> Reinforcement <br /> -flexural rigidity ASTM D5732-95' mg-cm 9,500,000(min) <br /> -tensile strength ASTM D6637 Method A-10' <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 1248-05 % 97(min) <br /> Type III/Class A/Grade 5 <br /> -carbon black ASTM 4218-96 % 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 Method A-10 without <br /> deforming test materials under load before measuring such resistance or employing "secant" or "offset" <br /> tangent methods of 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. Thickness <br /> Section 02776.1 Page 4 of 6 May 9,2012 <br /> Geogrid Revision 1 <br />
