Compound Curves. A compound curve consists of two (or more) circular curves between two main tangents joined at point of compound curve ( PCC ). Curve at PC is designated as 1 ( R1, L1, T1, etc) and curve at PT is designated as 2 ( R2, L2, T2, etc). Read more. Add new comment.

WebII. COMPOUND CURVE. A compound curve is a combination of two or more simple curves having the same direction of concavity. The two curves are joined at a point called the PCC (point of common curvature). The tangent at PCC is tangent to the first curve and also to the second curve and is called, the common tangent.
