e. C; - Soil Interaction Coefficient value shall be determined from long-term <br /> effective stress pullout tests per GRI-GG5, unless the junction creep <br /> testing of the geogrid is used to determine Ta. The C; value is determined <br /> as follows: <br /> C;= F <br /> 2 L 6N tan <br /> Where: F =Pullout force (lb/ft),per GRI-GG5 <br /> L=Geogrid Embedment Length in Test (ft) <br /> GN= Effective Normal Stress (psf) <br /> =Effective Soil Friction Angle, Degrees <br /> PART 3 EXECUTION <br /> 3.1 EXAMINATION <br /> A. The GEOSYNTHETIC CONTRACTOR and QA/QC CONSULTANT shall check <br /> the geogrid upon delivery to verify that the proper material has been received. The <br /> geogrid shall be inspected by the QA/QC CONSULTANT to be free of flaws or <br /> damage occurring during manufacturing, shipping, or handling. <br /> 3.2 PREPARATION <br /> A. The subgrade soil shall be prepared as indicated on the Construction Drawings or as <br /> directed by the DESIGN ENGINEER. Foundation soil shall be excavated to the lines <br /> and grades as shown on the drawings or as directed by the DESIGN ENGINEER. <br /> Overexcavated areas shall be filled with compacted backfill material. <br /> 3.3 INSTALLATION <br /> A. Geogrid shall be laid at the proper elevation and orientation as shown on the <br /> construction drawings or as directed by the DESIGN ENGINEER. Correct orientation <br /> (roll direction) of the geogrid shall be verified by the QA/QC CONSULTANT. <br /> Geogrid may be temporarily secured in place with staples, pins, sand bags, or backfill <br /> as required by fill properties, fill placement procedures, or weather conditions, or as <br /> directed by the DESIGN ENGINEER. <br /> B. Geogrid soil reinforcement shall be connected/spliced when required to provide <br /> continuity of tensile resistance. Geogrids shall be connected with a mechanical <br /> polymer bar. <br /> Forward Landfill WMU FU-04 <br /> 02779 6 GEOGRID <br />
