Performed soil density testing at above locations as per T310 using a nuclear density gauge model number 3440 and a standard proctor value of 117.0 pcf @ 12.1 optimum moisture. The tests met the required compaction on fill and contractor was informed of test results. See attached Field Density Report for results and locations. The common borrow used had previously been transported by conveyor belt from the Rolling Hills site south of Thunder Creek. The following items were verified: 1) Proper type of geogrid reinforcing was used and was not damaged prior to installation. 2) Checked to assure the minimum embedment depth was attained according to approved plans & specifications. 3) Checked that geogrid was attached together, subcontractor was using twist ties placing with 1' to 2' spacing and overlapping geogrid 2" to 6". 4) A total of 39 rolls of SF-55 and 3 rolls of SF-20 geogrid reinforcing was layed today. 5) Fill placed did not exceed 1' lifts verified by laser to check elevations each lift. 6) Geogrid was laying flat and not bundled up prior to fill. Foreman on site verified approximately 2465 cubic yards of material was placed today. Observed the two 350 offroad dump trucks driving over compacted material throughout the day with no deflection or yielding in the material. The CTI subcontractor placed a total of two lifts of fill today. The final lift at an elevation of 190 ft above sea level will be compacted further on Monday and will require testing then. TImothy I.
