20. Factors affecting pavement design

Try these first

1. 1.

   What is contact pressure?

   Hint

   Think about what happens at the tire interface.

2. 2.

   Name one type of structural model used in pavement design.

   Hint

   This model handles stresses and strains.

3. 3.

   What major factors affect pavement design?

   • Traffic and Loading
   • Structural Models
   • Environmental Factors
   • All of the above

   Hint

   Consider the categories we've discussed.

4. 4.

   True or False: Higher speeds of moving vehicles increase the deformation stresses in pavements.

   • True
   • False

   Hint

   Recall the difference in effects at slow speeds.

5. 5.

   A busy intersection experiences a high frequency of heavy trucks that create significant pavement deformation. How would you design a pavement to accommodate this traffic pattern?

   Hint

   Think about how traffic density impacts the design.

6. 6.

   Given seasonal temperature extremes, what actions would you recommend to mitigate damage to both asphalt and concrete pavements?

   Hint

   Consider how to account for thermal reactions in different materials.
