Performed observation and soil density testing on fill using common borrow over Miragird 3XT and SF-20 Geogrid reinforcing from stations 10+75 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 114.5 with a 12.9% optimum moisture was used per Mayes Testing lab number T-09082-26. The tests meet 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 10+75 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. A total of 3 1/2 rolls of SF-20 and 45 rolls of Miragrid 3XT 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. CTI placed a total of 2 lifts of fill over the Geogrid Reinforcing from a total of 144 truck loads for a total of 3600 cubic yards completing elevations 200 and 201. The Geogrid reinforcing at elevation 199 was inspected this morning after installation. The Geogrid Reinforcing at elevation 210 had not been placed yet and will be inspected tomorrow. Visited by Rod Blalock compliance inspector with WSDOT throughout the day. The Holding Point was reached at elevation 201. Rick Johnson the materials technician with WSDOT and myself spoke with Kevin the Foreman with CTI that all testing had been obtained and that it was alright for them to continue. Rick Johnson the materials technician with WSDOT performed a soils density test per T310 and obtained a sample per SOP 615. CDB continued to place quarry spalls along the ditchlines at station 10+00 and 15+95. The Defoor site was prepared for the upcoming rainfall this weekend.
