APPENDIX F
CURVE TABLES
FUNCTIONS OF A1-DEGREE CURVE
The long chords (C), middle ordinates (M), externals (E), and tangent distances (T) in Table F-1, are for a 1-degree curve, based on the arc definition (5,729.578-foot radius). To find the corresponding functions of any other curve, divide the tabular values by the degree of curvature.
CORRECTIONS FOR TANGENTS AND DISTANCES
Complete the following steps to determine the degree of curvature for all curves other than the 1-degree curve:
1. Determine the value corresponding to the given intersection angle from Table F-1.
2. Divide this value by the given degree of curvature.
3. Add the correction derived from Table F-2.
