Question $8$

PART $2$: Design and Analysis

Problem $1$: Determine the station of the PVC$,$ PVT$,$ and V of the curve

An equal tangent crest vertical curve connects a $+3\mathrm{.}2\%$ and a $-1\mathrm{.}1\%$ grade. The PVI is at station $98+20$

Due to drainage considerations, the highest point of the curve is at station $100+79\mathrm{.}35.$ Determine the

station of the PVC and PVT$,$ and the design speed of the curve. Pay attention to the units and write

your answer using the $+$ sign indicating stations, unless otherwise specified.

Sta $PVC=94+71\mathrm{.}51$

example: $56+54\mathrm{.}53($show the whole number don't omit zero's$)$

Sta PVT $=$

$V=122\mathrm{.}71,m\frac{i}{h}r$
