54.03 ROADS <br />• 4.03.2 Access Roads. <br />(3) (d) (iii) (Cont'd.) <br />peat material or any other material considered <br />unsuitable for embankment construction. No <br />excess material that required disposal was <br />generated from access road construction. <br />(iv) The access roads' embankment material came <br />from the cut colluviian. Due to the construc- <br />tion procedure required in the area of the Or- <br />chard Valley Mine, roads are 6ui1t up in a <br />continuous process of cut and Eill. It is not <br />possible to measure actual layers of Ei11 be- <br />fore compaction. The use of the road has not <br />been restricted due to placement of fill mate- <br />rial. <br />(v) See Section 4.03. 2(3)(d)(iv). <br />(vi) The existing access roads' use has not been <br />restricted due to placement of material. The <br />embankments are adequate to support the actual <br />• volume of traffic and weight and speed of ve- <br />hicles currently used. Current road construc- <br />tion procedures were used on all access roads. <br />This required that each layer of embankment <br />shall be completed, leveled, and compacted he- <br />fore succeeding layers are placed. The use of <br />a cut and fill technique permits this to be a <br />continuing process. <br />(vii) The construction was done under the direction <br />of a professional engineer, who ensured road <br />stability. No records of ASSHTO specified <br />tests or as constructed moisCure content tests <br />are available on existing access roads. <br />(viii) See Section 4.03.2(3)(c)(i). <br />(ix) Stability analysis for all road embankments <br />were completed by Plerrick and Company and Geo- <br />ilydro Consulting, Inc., both of Denver, Colo- <br />rado. All embankments studied are stable. <br />Refer [o the Stability Analysis Appendix, Vol- <br />ume 6. <br />• Revised 08/01/84 <br />Revised 10/01/87 <br />18 <br />
