COMPOUND CURVE

• A compound curve is the combination of two or more simple circular curves of different radii.
• Thus because of two different radii, the two centers will also be different.
• Because of different length of tangents, compound curve allows the fitting of location of a topography with enhanced refinement as compared to simple circular curve.
• As far as possible, where simple circular curve can be used there compound curve should not be used.
