KDOT Highway & Bridge Inspection Procedures 2

Question 1

During a routine bridge inspection, an inspector notices efflorescence on a concrete pier. What does this indicate?

Accepted Answer

Water infiltration and potential leaching of calcium hydroxide

Answer

Efflorescence is a white crystalline deposit caused by water moving through concrete and leaching calcium hydroxide to the surface, indicating moisture infiltration.

Question 2

What is the primary purpose of the AASHTO Manual for Bridge Element Inspection (MBEI)?

Accepted Answer

To standardize element-level condition ratings and quantities

Answer

The MBEI establishes standardized element-level condition states and quantities for consistent bridge inspection data collection across agencies.

Question 3

A Kansas inspector observes transverse cracking in a reinforced concrete bridge deck at regular intervals. The most likely cause is:

Accepted Answer

Shrinkage and thermal stresses during curing

Answer

Regularly spaced transverse cracks in bridge decks are typically caused by concrete shrinkage and thermal contraction stresses during and after curing.

Question 4

Under FHWA regulations, what is the maximum interval allowed between routine bridge inspections for most bridges?

Accepted Answer

24 months

Answer

FHWA regulations (23 CFR 650) require routine bridge inspections at intervals not exceeding 24 months for most bridges.

Question 5

When inspecting a steel girder bridge, spalling of the concrete deck over a girder flange is most likely caused by:

Accepted Answer

Corrosion of embedded reinforcing steel causing expansion

Answer

Corrosion of reinforcing steel expands the metal, generating internal pressure that causes the overlying concrete to crack and spall.
