NICET - Highway Construction Inspection Practice Exam

What must be ensured regarding the integrity of a concrete barrier during inspection?

1. Visual alignment only

2. Proper material selection

3. Absence of damage

4. Both alignment and absence of damage

The correct answer is: Both alignment and absence of damage

Ensuring the integrity of a concrete barrier during inspection involves both the visual alignment of the barrier and checking for any absence of damage. Visual alignment is crucial because it ensures that the barrier is positioned correctly to effectively perform its function, such as directing traffic or providing safety. If the barrier is misaligned, it could fail to protect vehicles or pedestrians as intended. The absence of damage is equally vital. Any cracks, spalling, or other forms of structural degradation can compromise the barrier's strength and its ability to withstand impacts. Damage could result from environmental conditions, wear and tear, or accidents, and identifying such issues during an inspection helps to maintain the barrier's effectiveness and longevity. By confirming both the visual alignment and the absence of damage, inspectors can ensure that the concrete barrier meets safety standards and performs reliably in its intended role.
