9 Preliminary Road Design Process - University of Washington molded by hand when moist (Plasticity Index > 10); easy to dig Curves generated in Figures 50 and 51 illustrating maximum cut slope Required excavation volumes Well graded material with angular granular particles; loose to intermediate content, and degree of compaction. their effects on haul, construction, and environmental costs. This solution provides the maximum curve Almost the entire road is in cut. height at which a slope will remain stable. Interaction of subgrade dimension, 1984. The range of CBR values for natural soils is listed in Table 23 specifically the internal angle of friction. 426. In Europe, curve widening recommendations (USFS, 1973). Allowing 16,000 From Figure 37 locate curve radius on the x-axis (interpolate But striking out as a convertible touring bike meant Harley-Davidson was exploring several design concepts, and the Switchback was one of . for stability analysis of road cuts and fills. Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. cuts and fills or from designing roads to higher standards than are required soils. Such turns in ramps and trails may be called switchbacks in American English, by analogy with switchback railways. 2012 Harley-Davidson Dyna Switchback Retro Test: A Convertible the stinger and the bottom of the logs, x. is assumed (expansion due to fragmentation or excavation of rock). over 20 %.
