Four simple curves (CURVE1, CURVE2 & CURVE3) are connected to form the highway curves. CURVE2 formed a compound curve with CURVE1. CURVE2 also formed a reverse curve with CURVE3. The common tangent of the compound curve is parallel to its long chord. The reverse curve has parallel tangents. CURVE1 Radius = 800 meters CURVE1 Long Chord = 170 meters CURVE1 Stationing of PI = 9 + 578.40 CURVE2 Radius = 520 meters CURVE2 Long Chord = 135 meters CURVE3 Radius = 750 meters CURVE3 Long Chord = 221 meters

Four simple cuve(curve1,curve2 & curve3) are connected to the highway curves. curve2 formed a compound curve withe curve1. curve2 also formed a reverse curve with curve3. the common tangent of the compound curve is parallel to its long chord. the reverse curve has parallel tangets.
curve1 radius= 800m
curve1 long chord=170m
curve1 stationing of pi = 9+578.40
curve2 radius = 520m
curve2 long chord = 135m
curve3 radius = 750m
curve3 long chord = 221 m
#2
using arc basis, compute the following and answer the following qustions:
1. what is the stationing of PC of the compound curve?
2. what is the stationing of PCC of the compound curve?
3. what is the stationing of PRC of the reverse curve?
4. what is the stationing of PT of the reverse curve?
