of the pit. The area chosen has only been worked by the compactor <br />and has not been travelled over by haul trucks going into and out <br />of the pit. Two trenches were excavated side by side. One trench <br />was excavated by the FD-30 bulldozer, the other trench was <br />carefully excavated by a backhoe, as recommended by the division <br />(Fig. 2,3)1. <br /> A <br /> <br /> HACICHOE <br /> TRENCH <br />HOZEii ~\ <br />TRENCH <br />s• HepTx - X X X <br />TEST SITE <br /> e-H• <br />]' DeeTH <br /> X X x <br />TesT sxxe <br /> -~.~ <br /> A' <br /> PLAN VIEW OF TEST SITE <br />Fig. 2 <br />Seven locations were selected <br />for measurements. The seven <br />locations were chosen by the <br />following criteria. All <br />locations were below the <br />existing frontline, which <br />extended about two feet below <br />the surface. Two locations <br />were located directly under <br />the dozer track at a depth of <br />three feet and six feet below <br />the surface of the pit. Two <br />more locations were located <br />between the dozer tracks at <br />the same depths. Two <br />measurements were taken at <br />the same depths in the <br />backhoe excavated trench. A <br />seventh location was located <br />in the side of the dozer <br />excavated pit. This location <br />was chosen to represent a <br />control point, in that the material being in the sidewall was <br />relatively undisturbed and had not been travelled over by any <br />equipment. <br />The wet density measurements were taken at each location and then <br />averaged. A sample of the refuse material was then taken from <br />1 Full size drawings are provided in the appendix <br />4. <br />
