The centerline of a portion for a proposed highway extension project is composed of four simple curves. These curves are connected to each other such that the first, second and third curve forms a compound curve, while the third and the fourth curve forms a reverse curve with diverging tangents. The compound curve is tangent to the lines AB, BC, CD & DE while the reverse curve is tangent to lines DE and EF. Point B is at Sta. 10+000. DEPARTURE POINT A B C D E F c. d. LATITUDE 0.00 -50.00 -147.66 -209.70 -171.93 -203.63 If the long chord of the 2nd curve is 1.644 times the length of the long chord of the first curve, solve for the ff: a. radius of the first curve b. radius of the second curve radius of the third curve radius of the fourth curve e. stationing of PRC f. stationing of the PT 0.00 0.00 63.42 170.88 251.87 319.84 The centerline of a portion for a proposed highway extension project is composed of four simple curves.
