15.1.4. Parameters in Performance Evaluation

Try these first

1. 1.

   What does rutting resistance refer to?

   Hint

   Think about the impact of repeated traffic.

2. 2.

   Why is skid resistance important?

   Hint

   Consider conditions like rain.

3. 3.

   What does rutting resistance measure?

   • Deformation under traffic loads
   • Cracking under temperature
   • Water damage

   Hint

   Consider what happens when many vehicles pass over a surface.

4. 4.

   Is moisture susceptibility important for all pavements?

   • True
   • False

   Hint

   Think about how moisture can penetrate surfaces.

5. 5.

   How would you evaluate a pavement project that failed due to moisture susceptibility? Describe the parameters you'd reconsider.

   Hint

   Consider the role of water in pavement failure.

6. 6.

   Calculate the impact of poor skid resistance on accident rates using hypothetical data.

   Hint

   Think about safety statistics related to road conditions.
