WebReverse Curve Data The computation of reverse curves presents three basic problems. The first is where the reverse curve is to be laid out between two successive PIs. (See figure 12.) In this case, the surveyor performs the computations in exactly the same manner as a compound curve between successive PIs. Weba compound curve is where the radius changes as you go through the curve, so it gets "Tighter" or "Broader" but that radius change shares a common tangent. Some good reading on the road curve wikipeida page. Nowadays with Cad and much less field design, these common traditions are being ignored more and more. prolube market st wilmington nc
