Performed observation and soil density testing on common borrow placed over SF-55 and SF-20 Geogrid reinforcing from stations 11+50 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 117.0 with a 12.1% optimum moisture was used per Mayes Testing lab number T-09082-24. 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. The common borrow being used was located on the north end of the site and had been transported by the conveyor belt and stockpiled on a previous day. The conveyor belt was not in operation today but the subcontractor was adding the belt extension that had arrived today. While the Geogrid Reinforcing was being installed from stations 11+50 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 2' spacing and overlapping the Geogrid 2 to 6 inches. 4. A total of 39 rolls of SF-55 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. The CTI subcontractor placed a total of 1 lift of fill over the Geogrid Reinforcing from a total of 17 truck loads for a total of 500 cubic yards finishing to elevation 188. Performed observation as 84 truck loads for a total of 2,225 cubic yards of unsuitable material was placed along the 2:1 slope between the ditchline and Geogrid reinforcing from stations 10+00 to 15+95 preparing slope for top soil and hydroseeding. This material was being transported from the stockpile located on the northeast corner of the site. Visited by Bob Pyle compliance inspector with WSDOT, Chad Webley Field Eng. with CDB, and AlexZimmerman with CSI Geosynthetics to see the progress of the project Observed the 350P offroad dump truck driving over the compacted areas throughout the day with appearing to have no deflection or yielding.
