What is the primary purpose of an expansion joint in a cement concrete pavement?
Correct answer: A. To accommodate slab expansion due to temperature rise
- A. To accommodate slab expansion due to temperature rise
- B. To improve the skid resistance of the pavement
- C. To prevent water from entering the subgrade
- D. To increase the compressive strength of concrete
Explanation
An expansion joint provides space for concrete slabs to expand when temperature increases. It helps reduce excessive compressive stress and possible buckling. It does not itself increase concrete strength or provide skid resistance.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
