The primary purpose of a transverse contraction joint in a cement concrete pavement is to:
Correct answer: C. Control cracking caused by concrete shrinkage
- A. Provide drainage through the pavement surface
- B. Increase the width available to moving vehicles
- C. Control cracking caused by concrete shrinkage
- D. Prevent vehicles from crossing the centre line
Explanation
A contraction joint creates a planned weakened plane where shrinkage and temperature-related contraction can produce a controlled crack. It does not primarily serve as a drainage or traffic-control feature.

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.
