Performed observation and soil density testing on fill using common borrow over Miragrid 3XT and SF-55 /Miragrid 3XT Geogrid reinforcing(remainder of used rolls being used in place of SF-20 Secondary Geogrid reinforcing) from stations 10+35 to 15+95, and non reinforcing area from stations 14+00 to 15+95. Performed soil density testing at above locations per T310 and SOP 615 (Method 1) using a Troxler nuclear density gauge model 3440. The moisture density relationship value of 115.9 with a 12.4% optimum moisture was used per Mayes Testing lab number T-09082-28. The test met the 95% required compaction. The contractor was informed of test results. See attached Field Density Report and Density Work Sheet for results and locations. While the Geogrid Reinforcing was being installed from stations 14+00 to 15+95 the following was verified: 1. Checked to assure that the proper type of Geogrid reinforcing was being used and was not damaged. 2. Checked to assure the minimum embedment depth was attained according to approved plans&specs 3. Checked that Geogrid was attached together, with the subcontractor using twist ties placed at a 1' to spacing and overlapping the Geogrid 2 to 6 inches. 4. There was 19 Rolls Miragrid and Miragrid 3XT/SF-55(remainder of the used rolls used in place of SF-20) for Secondary Geogrid reinforcing were placed today. 5. That fill being placed did not exceed 1'. The subcontractor is using a laser to check elevations on each lift. 6. That the Geogrid was laying flat and not bundled up prior to fill being placed. 7. The unused Geogrid was covered with black plastic to protect from the sun. Elevations 219 and 220 were completed from stations 14+00 to 15+95 with installation and inspection of the Primary Geogrid reinforcing at elevation 219. Performed observation of the fully loaded 350D offroad dump truck and water truck driving over the compacted areas and material appeared to be firm and unyielding.
