Geogrid manufacturer shall perform quality control tests at a frequency of at least every <br />50,000 ft of geogrid produced. <br />• <br />• <br />PART 3: EXECUTION <br />3.01 EXAMINATIONS <br />A. Conformance Testing <br />1. Geogrid manufacturer shall supply samples of geogrid to CQA ENGINEER for <br />conformance testing. Unless otherwise specified, samples shall be taken at a rate of one per <br />lot, not to exceed one conformance test per 100,000 square feet of geogrid. <br />2. For geogrid, the following tests shall be performed using the procedures listed in Exhibit C: <br />a. Mass per unit area <br />b. Aperture size <br />C. Wide strip tensile strength <br />d. Node strength <br />3. Geogrid shall be rejected if conformance test results do not meet or exceed the values <br />presented in Table 2.01. <br />3.02 INSTALLATION <br />A. Geogrid Deployment <br />1. No equipment or tools shall damage the geogrid by handling, trafficking, or other means. <br />2. No personnel working on the geogrid shall smoke, wear damaging shoes, or engage in other <br />activities that could damage the geogrid. <br />3. On slopes, the geogrid shall be securely anchored and then rolled down the slope in such a <br />manner as to continually keep the sheet in tension. <br />4. Geogrid panels shall be deployed in such a manner as to preclude wrinkles and folds. <br />5. Geogrid within the lined area shall be cut with a cutter approved by CC &V, such as <br />scissors. Unshielded razor knives are not acceptable. <br />6. Two layers of geogrid shall be installed as indicated on the Drawings. The layers will be <br />placed at right angles to each other as directed by the CERTIFYING ENGINEER. <br />Section 02776.1 <br />Geogrid <br />SAPro1ects \1125E CCV CQA \I - Tech Specs \02776.1 rl.doc <br />Page 5 of 6 <br />September 3, 2008 <br />Revision 1 <br />
