Surveying Highways Part 2: Vertical Alignment TSYH 3312

Upon successful completion, the student will be able to:

Module 1 - Elements of Vertical Alignment

• State and define the elements of vertical alignment and the relationship between vertical and horizontal alignment.
• Determine from established vertical points of intersection whether the vertical curves are crest or sag and determine the algebraic grade change.
• State and define the general abbreviations and terminology for symmetrical parabolic vertical curves.

Module 2 - Vertical Curve Geometry

• State and define the general components of the parabola, symmetric and nonsymmetric vertical curves.
• Identify and select the appropriate formula for calculation of specific elements given the appropriate variables.

Module 3 - Methods of Vertical Alignment Solution

• Use the appropriate charts to determine the required length of vertical curve based on established grades and points of vertical intersection.
• Select and employ the appropriate formulae to calculate all components of symmetric and non-symmetric vertical curves.
• Plot and graphically solve vertical curves at distorted scales.

Module 4 - Vertical Alignment Design Controls and Procedure

• State, define and discuss the controls and constraints of vertical alignment design.
• Complete the necessary calculations for the design of or revisions to vertical alignment design in terms of an established horizontal alignment and vertical alignment constraints.
