Best New Methodology for Bridge Inspections: 4 Types

Bridge inspection involves more than just looking at the structure from the ground. Different aspects of the bridge need to be inspected, including the deck, superstructure, and substructure. Different methods will be used depending on the type of inspection being done.


Which one you choose to depends on the bridge's condition, your resources, and other factors. This post will discuss each type of inspection so you can decide which type is best for your needs.

1. Visual Inspection


It involves looking at the bridge with your eyes and using binoculars or a telescope to get a closer look. Experts will check for any visible signs of damage, such as cracks, holes, or missing pieces. You'll also be looking for things that could cause future
problems, such as loose bolts or rust.

It is the standard type of inspection, and it's typically done every year. However, if a significant event like an earthquake could have affected the bridge's structure, a visual inspection might be carried out more frequently.


2. Ultrasonic Testing


Ultrasonic bridge inspection services in Arizona are used to detect flaws in the material. This type of testing uses sound waves that are sent into the surface of the bridge. The waves bounce back and are received by a transducer. The information is then sent to a computer, which creates an image of the bridge's internal structure.
It helps to detect:
- Cracks
- voids
- inclusions
- delaminations


3. Magnetic Particle Inspection
The best bridge inspection in Arizona uses magnetic particle inspection to check the strength of steel and iron components. It is done by using a magnet to check for any abnormalities in the metal. If there are any cracks or other damage, they will show up as dark spots on the surface of the metal.This method is accurate and can be used on small and large components. It is also relatively quick and easy to do.


4. Radiographic Examination


It involves the use of X-rays to check the soundness of a material. Here's how it works: a high-voltage X-ray machine is placed on one side of the object being inspected, while a film pack or image receptor is placed on the other. The X-rays that pass through the object are recorded on the film, then developed and interpreted by a qualified inspector.

This method inspects metal castings, welds, and other components for hidden flaws. It's also effective at detecting corrosion in metal bridges.
