The pinned connection must be manufactured from HDPE <br />materials and shall be manufacturer approved. <br />C. Defects and Repairs <br />All damaged geogrid rolls shall be discharged. No repairs shall be made. <br />3.03 PLACEMENT OF SOIL OR GRANULAR MATERIALS: <br />All soil materials located on tap of a geogrid shall be placed in such a manner as to ensure: <br />1. The geogrid is not damaged. <br />2. Minimal movement and wrinkling or folding of the underlying geogrid layerlsl <br />occurs. <br />3. No excess tensile stresses shall occur in the geogrid such as when earth moving <br />equipment makes sudden starts, stops, or turns. <br />4. Soil placement over the geogrid shall be performed with construction equipment <br />approved by the ENGINEER. Such construction equipment includes low to <br />moderate ground pressure dozers (e.g., D-6 or D-8 CAT dozed. Dozers will push <br />soil materials over the geogrid from the bottom of the slope in an uphill direction. <br />5. A minimum of 6" of soil cover shall be placed over the geogrid layers. No <br />construction equipment shall operate directly on the geogrid layer or on less than <br />6" of soil cover. <br />6. Soil cover over the geogrid shall consist of Select Structural Fill and shall be <br />compacted and placed according to Select Structural Fill SPECIFICATIONS in <br />Section 2200. <br />7. Extent of geogrid reinforced areas shall be surveyed and staked in the field by the <br />CONTRACTOR. Subsequent construction activities over the reinforced areas shall <br />not damage geogrid or reduce soil cover thickness to less than 6 inches. <br />March 22, 1996 Section 02776.1 <br />02276.1-6 Geogrid <br />Revision 1 <br />
