Q4. A falling gradient of P % meets a rising gradient of Q % at a reduced level of LLL.LLL m and a through chainage of QQQQ m. A parabolic vertical curve having equal tangent lengths is to be used to connect the gradients and the K Value for the curve is KK. As a civil engineer you are request to prepare the setting out data based on the vertical curve design parameters given. a) Calculate the reduced levels and chainage of the tangent points, setting-out data at exact 20 m interval, the through chainage and reduced level of the lowest point on the proposed vertical curve. b) If a vertical curve is to be constructed to join two gradients +p % and -q % with the the height of driver view and sight distance for a driver whose height is H.HH m above the road surface is XXX m, respectively. Discuss how to solve this issues in determining the design length of the vertical curve required (parameters for +p %, -q %, H.HH & XXX m not provided. Just discuss the method of solution in determining the length of curve).
