46. What is the purpose of providing dowel bars in transverse joints of cement concrete pavements?

1. To increase load-carrying capacity
2. To maintain alignment and smoothness
3. To control cracking due to shrinkage
4. To transfer loads between adjacent slabs

Answer

The correct answer is: D) To transfer loads between adjacent slabs
