Curves. Horizontal. Introduction. Use of curves, horizontal and vertical. Types of horizontal curves: Circular and spiral. We will cover circular curves only, spiral curves are given for future reference. Definitions :
Curves. Horizontal. Circular Curves Layout by Deflection Angles with a Total Station or an EDM. All stations will be positioned from PC. Compute the chord length and the deflection angle from the direction PC-PI as follows: (see fig 25-6). S a D. C a = 2R sin a. a =. (degrees).
Readings: 24-1 to 24-8, Figures: 24-1 to 24-6, 24-12, and 24-16 Examples: 24-1, 24-2, . Curves. Horizontal. Required: Readings: 24-1 to 24-8, Figures: 24-1 to 24-6, 24-12, and 24-16 Examples: 24-1 and 24-2. Introduction. Use of curves, horizontal and vertical.
Time-distance (T-X) curves Single horizontal layer. T 2 = T 0 2 + X 2 /V 2 . It is a hyperbola with apex at X = 0 and T 0 = 2H/V. V and H are the layer velocity and thickness. T 2 -X 2 plot is a straight line whose slope = 1/V 2 and intercept = T 0 2 .
Curves. Horizontal. Required: Readings: 24-1 to 24-8, Figures: 24-1 to 24-6, 24-12, and 24-16 Examples: 24-1 and 24-2. Introduction. Use of curves, horizontal and vertical. Types of horizontal curves: Circular and spiral.
Horizontal Integration. Consolidation (business) More than 50% ownership — Subsidiary. horizontal integration:is the combination of firms in the same business lines and markets. Peace journalism - Objectivity.
Horizontal Curves. Chapter 24. Types of Circular Curves. Simple Curve. Compound Curves. Broken-Back Curves. Reverse Curves. Broken-Back Curves should be avoided if possible. It is better to replace the Curves with a larger radius circular curve.

HORIZONTAL ALIGNMENT . The presence of horizontal curve imparts centrifugal force which is a reactive force acting outward on a vehicle negotiating it.
