ameO <br /> 7. The subgrade shall be prepared for geogrid placement by uniform grading. No steep grade <br /> changes or edges shall be allowed. The CERTIFYING ENGINEER shall approve the <br /> subgrade prior to geogrid installation. The subgrade must not be smooth rolled. <br /> B. Joining <br /> 1. The geogrid shall be placed in continuous pieces downslope. <br /> 2. If the geogrid is to be joined end to end, a pinned connection splice shall be used. The <br /> pinned connection must be manufactured from HDPE materials and shall be <br /> MANUFACTURER approved. <br /> C. Defects and Repairs <br /> 1. All damaged geogrid rolls shall be rejected. No repairs shall be made. <br /> 3.03 PLACEMENT OF SOIL OR GRANULAR MATERIALS <br /> All soil materials located on top 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 layer(s)occurs. <br /> 3. No excess tensile stresses shall occur in the geogrid such as when earth-moving equipment makes <br /> sudden starts,stops,or turns. <br /> 4. Soil placement over the geogrid shall be performed with construction equipment approved by the <br /> CERTIFYING ENGINEER. Such construction equipment includes low to moderate ground <br /> pressure dozers(e.g.,D-6 or D-8 CAT dozer). Dozers will push soil materials over the geogrid from <br /> 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 construction equipment <br /> shall operate directly on the geogrid layer or on less than 6"of soil cover. <br /> 6. Soil cover over the geogrid shall consist of Select Structural Fill and shall be compacted and placed <br /> according to Select Structural Fill SPECIFICATIONS in Section 2200. <br /> 7. Extent of geogrid-reinforced areas shall be surveyed and staked in the field by the CONTRACTOR. <br /> Subsequent construction activities over the reinforced areas shall not damage geogrid or reduce soil <br /> cover thickness to less than 6 inches. <br /> *** END OF SECTION*** <br /> Section 02776.1 Page 6 of 6 May 9,2012 <br /> Geogrid Revision 1 <br />
