15.5.2. Road and Highway Projects

Try these first

1. 1.

   What is horizontal alignment?

   Hint

   Think about the straightness or curvature of the road.

2. 2.

   Define vertical alignment in road design.

   Hint

   Consider how hills and valleys are incorporated in roads.

3. 3.

   What is the primary goal of horizontal alignment in road design?

   • To define the road elevation
   • To establish the path of the roadway
   • To determine drainage system

   Hint

   Think about the road's pathway, whether it's straight or curved.

4. 4.

   Ultimately, what makes super-elevation necessary?

   • True
   • False

   Hint

   Consider how vehicles might react on a curve.

5. 5.

   Given a terrain map with varying elevations, outline how you would establish both horizontal and vertical alignment for a new highway.

   Hint

   Refer to the principles of alignment discussed in class.

6. 6.

   Analyze a highway project with improper drainage and propose a solution based on cross-section layout.

   Hint

   Think about how water flows and the importance of proper slope.
