This course provides a thorough knowledge of the properties and behavior of horizontal and vertical curves used in highway work, mainly in the use of laying out the alignment of a proposed roadway.

The center alignment of a road consists of a series of straight lines interconnected by curves that are used to change the alignment, direction, or slope of the road. Those curves that change the alignment or direction are known as horizontal curves, and those that change the slope are vertical curves.

Topics: Types and Elements of Horizontal and Vertical Curves Degree of Curvature (Arc and Chord definitions) Curve Formulas Tangent / Chord Distance Length of Curve Middle Ordinate, External Distance Deflection Angles and Chords Solving and Laying Out a Simple Curve Inputting Field Notes Vertical Curve Grades, Gradients Symmetrical and Asymmetrical Curves Checking Computations by Plotting Using a Plan and Profile Worksheet Field Stakeout of Vertical Curves

Intended Audience: This course is intended for Transportation, Civil, Geotechnical, Construction, Architectural, Water Resources, and other engineers whose job description requires a basic knowledge of surveying principles and methods used in roadway construction and design.
