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. While the Geogrid Reinforcing was being installed from stations 10+35 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 49 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. Elevations 205 was completed with installation and inspection of the Primary Geogrid reinforcing from stations 10+35 to 15+95. Fill was placed to elevation 206 from the same station numbers but no Secondary Geogrid reinforcing was placed at this elevation yet. CTI placed a total of 650 cubic yards from a total of 26 truck loads from my arrival until the end of the work day. There was a total of 4,818 cubic yards of common borrow transported today by the conveyor belt from a total of 219 truck loads. Performed observation of the fully loaded 350D offroad dump trucks driving over the compacted areas and material appeared to be firm and unyielding. Was visited by Chad Webley the Field Engineer with CDB, Dave Zimmerman with CDB, and Roch Player the Engineer with CDB to see the progress of the project. Terra Dynamics had completed the installation of the nonwoven coconut matting along the 2:1 slope from elevations 171 to 191 and stations 10+00 to 15+95 at the time of my arrival. Visited by Rod Blalock compliance inspector with WSDOT throughout the day who was notified about the Holding Point at elevation 206. Was informed by Rod Blalock that Rick Johnson the Materials Technician with WSDOT will be performing soil density test tomorrow.
