RDC EVERETT TRANSFER FACILITY Everett,Washington <br /> summarized in Figure B-2. The plasticity chart relates the plasticity index (liquid limit minus the 1 <br /> plastic limit)to the liquid limit. <br /> CBR Testing 1 <br /> A CBR test was performed on two samples obtained from the fill below the existing pavement <br /> sections by collecting the drill cuttings. Samples from borings B-1 and B-2 were combined and <br /> samples from borings B-6 and B-8 were combined. The CBR tests were performed in general <br /> accordance with the ASTM D 1883 test procedure. The maximum dry density (MDD) and optimum <br /> moisture content of the samples were determined in general accordance with ASTM D 1557. The 1 <br /> CBR samples were then remolded to between 89 and 97 percent of the MDD at approximately <br /> the optimum moisture content as determined by ASTM D 1557. The samples were then soaked <br /> for a minimum of 24 hours prior to testing. The results of the CBR test are presented in the <br /> following table. <br /> Sample Depth Percent Maximum 1 Exploration (feet) Soil Type Dry Density CBR(0.1") <br /> 90.7 15 <br /> B-1/B-2 1 to 3 SP/SM/GM 95.9 51 <br /> 99.5 82 <br /> 91.9 7 , <br /> B-6/B-8 1 to 3 SM 95.4 47 <br /> 99.9 61 1 <br /> I <br /> I <br /> i <br /> 1 <br /> 1 <br /> 1 <br /> I <br /> 1 <br /> Page B-2 June 18,2013 GeoEngineers,Inc. <br /> File No.4322-002-00 <br />
