Using the same roads (elevations etc.), design a clover-leaf ramp for eastbound traffic going north. The ramp is to consist of a horizontal curve starting on the east-west highway with a PC starting at station 49+60. For this ramp, a 12 percent superelevation is to be used with a 40mi/h design speed. Determine: • the length of the ramp • minimum M s for horizontal curve sight distance • length ofvertical curves • give stations only (no elevations) of PVC's, PVT's, PC's and PT's 4'\+(,.0 6J\$f _\AJ:. .:. .S_S~T-1-........ 1>;;:;:c::.:-------------_G-::: 0'7. i> T "'------ro ~ '" o I ~ o 2...
