of sufficient proportions , to interfere with use of the road, or <br /> damage capable of contributing to further instability which may <br /> endanger the road. Included here are isolated areas of import- <br /> ant instability within otherwise stable zones. Vegetation cover <br /> is described as none to occasional , sparse to fair and good to <br /> excellent. For the water seeps parameter, cuts are classified <br /> as dry, having occasional seeps, or having important seepage. <br /> The category of important seepage includes isolated areas of <br /> important seepage from otherwise dry or occasional seepage <br /> zones . <br /> Road fill parameters are height , fill slope , fill <br /> stability, vegetation cover and water seeps. Fill height is <br /> defined as up to 20 feet, up to 40 feet or up to a height <br /> greater than 40 feet. Fill slope is described as zero to 30 <br /> degrees from horizontal or 30 to 45 degrees. The categories for <br /> fill stability, vegetation cover and water seeps are broken <br /> down in the same manner as those for cut slopes. <br /> Table 11 presents the summary of road configurations and <br /> geotechnical conditions for the combined length of all roads. <br /> The cut and fill parameters and categories are identical to <br /> those of the individual haul road summaries, and the lengths of <br /> roads in each category are given in feet and percentage of the <br /> entire combined length of all the haul roads. <br /> Table 12 presents a summary of the avalanche danger to the <br /> haul roads. The length of each road is divided among three <br /> categories; road exposed to annually running avalanches, road <br /> exposed to less severe avalanche danger, and road exposed to no <br /> identifiable avalanche danger. Again, lengths of road are given <br /> in feet and in percentage of total road length, and a summary <br /> is given for the entire combined length of all the haul roads. <br /> 3. 2 DESCRIPTION OF HAUL ROADS <br /> Road A (see Table 3) between the wash plant and the <br /> junctio-' n oI B and A roads is 6, 400 feet long , with an average <br /> grade of 8. 1%. Most of the road length is in a cut and fill <br /> configuration; a part of the road crosses the yard in the <br /> vicinity of the wash plant. The majority of the road cuts are <br /> in soil and their height is limited below 40 feet. Most of the <br /> cut slopes are steep (up to 600) ; the minor part are steeper. <br /> The majority of the fills are low (below 20 feet) , the <br /> remaining fills are less than 40 feet high. Practically all the <br /> fills appear to have been constructed at the angle of repose <br /> (30 - 450) . <br /> 11 <br /> GE044MRO CONSULTING,INC. <br />
