(The turning point is thehigh or low point on a vertical curve. When the tangent grades are equal,the high or low point will be at the center of the tune. When the tangentgrades are both plus, the low point is at the PVC and the high point is atthe PVT. When both tangent grades are negative, the high point is at thePVC and the low point is at the PVT. When unequal plus and minustangent grades are encountered, the high or low point will fall on the sideof the curve that has the flatter gradient.)Chapter 12A1.
