Question 1

What is the primary material used for rigid pavements?

  • Asphalt
  • Cement Concrete
  • Gravel

💡 Hint: Think about materials that provide strength and durability.

Question 2

True or False: The modulus of sub-grade reaction is calculated from slab displacement and pressure.

  • True
  • False

💡 Hint: Remember the relationship between pressure and how much the slab sinks.

Challenge Problems

Push your limits with challenges.

Question 1

A cement concrete pavement of thickness 30 cm needs to be designed to withstand a wheel load of 6000 kg. Calculate the required modulus of sub-grade reaction if the slab shows a deflection of 0.15 cm.

💡 Hint: Focus on the ratio of force to the resultant deflection.

Question 2

Design a dowel bar system for a joint with 50 cm spacing, assuming a wheel load of 4000 kg. What is the load transfer capacity needed?

💡 Hint: Remember the capacity factor principle we discussed.
