~`.' <br />SMITH WILLIAMS CONSULTANTS, INC. <br />~~ <br />permeability testing was conducted on representative remolded samples from the clay borrow <br />area. The material was first sieved to remove oversize particles and then recompacted to <br />95 percent of a standard Proctor maximum dry density at or near the optimum moisture content. <br />The flexible wall permeabilities range from between 2.8X_10"5 and 1.08X 10-g with a geometric <br />mean of 6.6X 10-'. The borrow source samples sieve analyses indicate an average of <br />approximately 32 percent passing the No. 200 sieve with a range between 2 and 98 percent. The <br />hydrometer tests indicate that 10 to 25 percent of the material consists of clay-sized particles <br />(less than 2 microns). The results of the Atterberg limits tests indicate that the liquid limit ranges <br />from non-plastic to 56 percent with an average of about 33 percent and a plasticity index range <br />between non-plastic and 33, with the average of about 16 percent. <br />C] <br />• <br />S:\PROJECTS\1125 CCRV PHASE 5 VLF\H2 - DESIGNWREQUA VLFNLF PHASE 5 FINAL REPORT V2.DOC 19 <br />
