' SUBSURFACE CONDITIONS <br /> ' Subsurface conditions at the site were investigated by exca ating and <br /> sampling five exploratory test pits. Locations of exploratory test pits are shown <br /> on Fig. 2. Graphic logs of the soils found in the exploratory test pit , including <br /> field penetration resistance tests are included on Figs. 3 through 5. ubsurface <br /> ' conditions encountered in the exploratory test pits consisted of 1 to 10 feet of <br /> man placed fill material underlain by native soils. The fill material a countered <br /> twas relatively similar in each of the test pits excavated. The fill material was <br /> tclean to silty, sandy gravel with cobbles, dry, gray and brown a d angular <br /> (fractured). We noted some compactive effort. The native soil w s silty to <br /> ' clayey, gravelly, cobbles with boulders, lightly to moderately cemente , dry and <br /> ' red. Ground water was not encountered in the test pits the day of exca ation. <br /> ' Selected samples were tested in our laboratory for engineering I roperties. <br /> ' One sample of the fill material had a natural moisture of 2.7 percent, exhibited <br /> ' non-liquid and non-plastic characteristics with 7 percent retained on th No. 200 <br /> sieve (silt and clay sized particles) and 61 percent retained on the N . 4 sieve <br /> ' (gravel sized particles). Another sample tested had a natural moish re of 2.5 <br /> ' percent with 41 percent passing the No 200 sieve (silt and clay sized particles) <br /> and 53 percent retained on the No. 4 sieve (gravel sized particles). Or e sample <br /> ' was tested for fractured faces content. This sample exhibited 100 per ent 2 or <br /> ' Rhino Engineering,Inc. <br /> ' Unaweep Quarry <br /> GEG Job No.593 6 <br />
