Foundation Layer and Sideslope Subgrade Soil <br /> • Foundation Layer soil and Sideslope Subgrade soil are the same materials that have been shipped to SGI. <br /> • Compact Foundation Layer soil and Sideslope Subgrade soil at 90 percent relative compaction and OMC+4%based on ASTM D1557(Yd—=98.5 pcf,OMC=23.0%). <br /> 2. LCRS Gravel <br /> • Use rounded to subangular gravel,3/4"+/-nominal size,with 20%sand. <br /> 3. Operations Layer Soil <br /> • Loosely tamp the Operations Layer soil at its natural moisture content <br /> 4. Soak the GCL separately outside the shear box at 125 psf,Apply normal stress first and then start soaking. <br /> 5. For the Base Liner,spray lower surface of GCL and upper surface of geomembrane with distilled water. <br /> 6. For the Side Slope Liner,spray lower surface of geocomposite,both surfaces of geomembrane and upper surface of GCL with distilled water. <br /> 7. Please measure and report asperity height of geomembrane(both sides). <br /> 8. Please measure and report moisture content of GCL before and after the test and peel strength of GCL. <br /> Adv&#=&W <br /> P:\14 Projects\14-101 (SJCDPW North County and Foothill)\Foothill CQA\ReporATablesUnterface Configuration-Foothill LF.xlsx � h <br /> o.w•dwweM nw em-ww•n«,rd c�nwn.M, <br />
