Road A. Length is 6,400' long, with an average grade of 8.19. <br /> The majority of the road cuts are in soil and their height is <br /> limited below 40 feet. Most of the cut slopes are steep (up <br /> to 60%) , the minor part are steeper. The majority of the <br /> fills are low (below 20 feet) , the remaining fills are less <br /> than 40 feet high. <br /> Road B. Length is 3,4001 ,, with an average grade of 10a. The <br /> major part of the road is agin in thecut and fill <br /> configuration. Nearly all road cuts have been excavated in <br /> soils; the height of the cuts is limited to no more than 40 <br /> feet. All cut slopes are steep (up to 60t) ; no steeper slopes <br /> have been identified. The majority of the fills are low <br /> (below 20 feet) ; the remaining fills are not more than 40 feet <br /> high. All fill slopes appear to coincide with the angle of <br /> repose (30 to 4531) . <br /> Road C. 15,8001 in length, average grade of 8.0t. More than <br /> half the road is in cut and fill configuration, and nearly 20t <br /> of the road length has no significant earthwork. The majority <br /> of cuts are in rock, and are under 40 feet in height. A few <br /> cut slopes stand over 60 feet high. The slope of cuts tends <br /> to be relatively steep, usually up to greater than 602. The <br /> majority of fills are less than 20 feet high and have been <br /> constructed at the angle of repose (30 to 45--- ) Fills <br /> occasionally range up to greater than 40 feet in height, at <br /> the angle of repose. <br /> Road D-A. 6001 in length, at a grade of 9.2%. Half of the <br /> road is in cut and fill construction and the other half is in <br /> cut only. Cuts are either in rock or mixed soils and rock. <br /> Heights of cuts ange up to a maximum of 40 feet, and none are <br /> less than 20 feet high. Angles of cuts are steep, often <br /> exceeding 602. Fills are low, and range up to 40 feet in <br /> height. All fill slopes stand 30-452, the approximate angle <br /> of repose. <br /> Road E. 6,2501 in length, average grade of 8 .5t. Most of the <br /> E road is in cut and fill configuration. Road cuts are <br /> distributed between soil and rock. Most cuts are less than 40 <br /> feet in height, but ocasionally range up to 60 feet high. Cut <br /> slopes are steep, with many cuts steeper than 600- Fills are <br /> generally less than 40 feet in height, but exceed 40 feet in <br /> a few locations. Again, all fills are constructed at the <br /> approximate angle of repose (30-452) . <br /> Road F. 13,400 feet in length, with an average grade of 8.5t. <br /> Again, most of the road is constructed in cut and fill . The <br /> majority of cuts are in rock. Heights of cuts range up to 60 <br /> 2 <br />
