Centerline route tangents are provided for a roadway design You are to provide stakeout information for the route. Horizontal curves will be created at all tangent intersections. Part 1: Route with Curve Information Required Curve 1: • PI: •R: .A: •T: . • Station PC: • Station PT: . Distance between Curve 1 and Curve 2: Curve 2: • PI, R: A: L: Station PC: Station PT : Distance between Curve 2 and Curve 3: Curve 3: PI: . •R: • A,: •T: .L • Station PC: • Station PT Distance between Curve 3 and Curve 4: Curve 4: PI OR ܨܠ• . •T, : L: .
Distance between Curve 3 and Curve 4: .S, Curve 4: .PL •R, -Ag: . La • Station PC: • Station PT, Distance from Curve 4 to end of route 87+50: Part 2: Drawing with Curve Data After you have determined curve data, create a drawing of your centerline route with curves and labels of curve/route data. Part 3: Offset Curve Data for Curve 1 (Only needs to be completed for curve 1) The proposed roadway will include two, 12° wide lanes with a 10' wide shoulder on each side. Determine deflection angles and chord lengths for stakeout of the curves with offsets. Stakes are to be set at the PCs, PTs, and half station intervals along offset I would recommend completing this part of the project in excel. Offset curve data required: Curve 1: Curvel Chord Length: Chord Length: Chord Length: Chord Length: curves. Station Deflection Angle Inner Edge of Outer Edge of Inner Edge of Outer Edge of Pavement (1) Pavement Shulder ( Shoulder (1) Part 4: Drawing of Curve 1 with Offsets After you have determined offset curve data, create a drawing of curve I with lanes, shoulders, and labels of curve offset data.
