MORRISON-KNUDSEN COMPANY,INC. <br /> The drilling and sampling method is outlined below: <br /> Type of Type. of <br /> Type of Undisturbed Disturbed <br /> Material -Drilling Sampling Sampling <br /> Coal Refuse Hollow 6" Dia. 2.42" dia. <br /> Stem Auger Dennison Dames & Moore <br /> Air Rotary Samplers Ring Samplers <br /> Foundation Air Rotary 2.875" dia. 2.42" dia. <br /> Material Shelby Tubes Ring Samplers <br /> A total of 9 drill holes were completed. In addition, bulk samples <br /> were obtained from channels cut into two dozer trenches. The locations of <br /> the drill holes and dozer trenches are shown on Fig. 1 .1 . <br /> Field densities of the refuse material were determined for 21 locations <br /> using a Soiltest Volumeasure. <br /> A detailed description of the sample location, numbers and method of <br /> collection is provided in the Wahler & Assoc. report and therefore, is <br /> not repeated in this report. <br /> 1 .6.2.1 Type of Tests Performed <br /> A number of tests were perfo reed both on the refuse and the founda- <br /> tion material to determine their physical properties. The types of tests <br /> performed were as follows: <br /> Refuse material - <br /> • Compaction tests <br /> • Relative density tests <br /> • Permeability tests <br /> • Isotropically consolidated - drained triaxial tests <br /> • Water content and dry density determination <br />�• • Specific gravity determination <br /> 1-15 <br />
