NORTHWEST COLORADO CONSULTANTS, INC. <br />Project: Batch Weigh Loadout Project No.: 02-5023 Date: 9/11/02 <br />Haul Road Time: 4.0 <br />Location: Foidel Creek Mine Report No.: 1 Mileage: 40 <br />Client: RAG EngrJTech: JK <br />Work Performed: <br />As requested, we visited the project site on this date to provide construction observation and conduct nuclear <br />density test No.'s 1 through 5 on the material being placed for roadway embankment fills. <br />The Twentymile Coal Company Excavating crews placed and fire rolled 1 '/z loose lifts of on-site borrow material <br />to construct the subgrade of the proposed haul road between the batch load facility and the existing <br />East/Westbound road approximately 450 feet to the north. Crews had placed materials in lifts to total depths <br />ranging from several inches at the north and south ends of the road to approximately 10 feet of material adjacent <br />to the 48" CMP situated 215 feet south of the east/west haul road. Additionally, a 24" CMP was installed <br />approximately 185 feet to the south of the 48" CMP. Approximately 2-3 feet of material was placed above the <br />CMP. The roadway was constructed to a width ranging from 24 feet to 30 feet. <br />Remarks: <br />We observed the empty loader "tire rolling" the placed material attempting to achieve compaction. We noted that <br />the materials did not pump or deflect after multiple passes and that the material appeared to be near optimum <br />moisture content. <br />The material tested generally met the project specifications for compaction and moisture content. <br />Please refer to the attached sheet for results of today's testing. <br />Verbal Discussions: <br />Dave Wallace of Twentymile Coal Company was notified of today's test results. <br />
